Test automation plays a decisive role in software development in finding errors, vulnerabilities and areas for improvement. Suitable test automation tools can quickly test numerous factors to a very large extent once they have the testing criteria. With the help of the results, the software tester can target specific points or software components and will then perform manual tests and a detailed code review.

Through repeated testing, logging results and partly through an automatic evaluation, test automation makes it possible to check the software in various scenarios. This is often the only way to find such problems which usually aren’t found in one-off tests in standardised environments.

What is tested with test automation

A test automation test run checks a number of test cases in a single run. The resulting metric lets you create an objective comparison criterion, which lets the software be assessed qualitatively. Improvements or even deteriorations then become obvious through the modified program code.

Test automation can also answer a number of important questions on the basis of the specific test results:

  • Was a specific bug fixed?
  • Was a specific requirement met by the software?
  • Who on the development team is responsible for which problems and solutions?
  • Is a specific developer finished with their work?
  • What level of quality does the software reach, or what stage of development is it at?
  • Is one software version better than the other?
  • Does troubleshooting or a new component change the overall behaviour of the software?
  • What instructions or specifications need to be included in the documentation?
  • Does it keep to the set schedule, or does it need to be adapted?
  • Is the software ready for release?

The test automation is a dynamic process in relation to these specific questions. In the context of these test runs, new test cases or entire test routines will be defined to be able to focus on specific aspects and problems. This especially concerns critical errors which are only resolved once all individual test cases have been successfully passed.

Test automation and outsourcing

There is a range of suitable tools for test automation. A specific automation tool will be most suitable depending on software type and programming language. Each of these tools follows a different operating philosophy and even syntax and semantics will differ from case to case.

It is therefore an essential criterion when selecting a software tester that they are experienced in the preferred tools of the developer team. As you can see in the Wikipedia list of software for automated software tests, and the corresponding category for testing tools, there is a huge selection possible.

Since almost all test automation tools are used all over the world, it is almost always possible to find an expert as an outsourcing professional for a specific tool. India especially has many well-educated software testers who are often also excellent software developers, thanks to its booming IT sector. In comparison to European workers, you can save a lot of money this way. And it is often better to use an outsourcing specialist, rather than wait for a software tester to learn the test tools.

Usability testers are essential in the development process. A usability test checks if an application, app, website or other software product is suitable for the target user group. In contrast to code-based software tests, where many automatic processes play a role, usability testers focus on practical user experience.

Typically, these practical tests take place relatively late in the development process, and are conducted with alpha or beta versions. Since extreme changes at this stage of development are very time-consuming and expensive, and can significantly push back the release data, usability testers are very important.

Usability tester: the more the better

Usability testers need a lot of experience with the type of software being tested, and should be very familiar with the products of its main competitors. Their work is hampered by the relatively high amount of subjectivity they use to evaluate the software. Through a well-defined set of criteria with point scales and quality parameters, tests can be standardised to a certain extent, and then be statistically assessed.

If you use more than one usability tester – preferably in a large group – the results are more significant and are more understandable for the developers and product owners. Usability tests can also be combined with large focus groups, which through beta tests will increase the amount of quality feedback.

In every scenario realistic use tests are time-consuming and therefore expensive tasks. This means that they are unfortunately often omitted or only carried out to a small extent. There could also be a conflict of interest with the developers or project managers involved, whether out of a fear of delays, from criticism or a know-it-all attitude.

To receive uncompromising and open feedback, many companies prefer to use external usability testers through specialised providers. These are highly experienced thanks to their high expertise in the area, and can work more efficiently and affordably than a usability tester in a company.

Important criteria for a usability test

Although the exact test criteria will differ from product to product, there are a number of key factors for software usability. These should be at the centre of software design and development. Usability testers use them for control purposes to set the individual parameters and test criteria for specific tests.

  • Does the software meet a practical benefit?
  • Is the software able to be used intuitively?
  • Does the software respond quickly to input?
  • Are the quasi and official standards of the software type followed?
  • Is there useful/valuable feedback on input?
  • Is the user experience / operation consistent across all input masks?
  • Is the software reliable and professional?
  • Does it look good and work well?
  • Is it fun to use the software?

Usability testers are used for different software types from office software, to mobile apps up to interactive websites, and apply these meta-criteria to all of them.

Usability tester from India

If you have defined exactly how and to what extent you want to test your software’s usability, then you will not only save a load of money with an Indian usability testers, but will also increase the tests’ validity.

In the country known for its IT outsourcing, qualified usability testers charge only a fraction of their counterparts’ rates in Europe. There is also a large selection of agencies which specialise in qualitative usability tests, which will perform usability tests on a larger scale, and will use focus groups if needed.

Qualified app testers are essential for an app idea to be a truly resounding success. A critical outside perspective is often better suited to find the vulnerabilities of an app, rather than only using developers involved in the project and UX professionals.

In addition to unbiased analysis and a trained eye, an experienced app tester will have their own methodology to find errors, problems and opportunities for improvement.

What an app tester assesses

The test instruments of an app tester depend very much on the interface used. There are huge differences between Android, iOS and Windows Mobile when it comes to the hardware.

Android has many versions, as well as being very fragmented in the hardware, and an app should be able to run on as many devices as possible. Android Lollipop (5.0-5.1) has been on the market since October 2014 and only has a market share of 35.6%. Currently, most devices with run Android KitKat (36.3%), and Android 4.1-4.3 Jelly Bean is also well-represented with 21.7%. An Android app tester should therefore have a large arsenal of smartphones and tablets to be able to test the app under as many different scenarios as possible.

If you would like to create an iOS app, you will only need to worry about a few different devices (iPhone 3, 4, 5, 6 iPad 1-5 Generation, as well as iPad mini/Pro), because Apple is the only manufacturer for iOS hardware. It is also a bit easier for Windows Mobile.

An app tester will play through the available app capabilities in all variations and facets. Stability and performance play a prominent role here and the following questions are at the heart of a professional app test:

  • How long does it take to start the app?
  • How quickly does the app respond to input?
  • How does the app react during multi-tasking?
  • How high is the memory requirement for the app?
  • How much battery does the app consume?
  • How much data does the app transfer during normal operation and as background activity?

These and other technical parameters can be reviewed and logged by the app tester accordingly on the various devices. Then you have the purely qualitative tests, which relate to the app idea and its implementation:

  • Can the app be operated intuitively?
  • Does the menu structure make sense?
  • Are there any important features missing?
  • What features have errors?
  • Where is the app better or worse in comparison to similar apps?

The app tester should accurately record the technical test runs, and not use vague descriptions or their own subjective opinions. This is not possible in equal measure for qualitative tests, as the experience of the app tester plays an important role. With regards to the usability, it is possible to create accurate documentation with comparisons to other apps through lists and tables, as well as illustrations with app screenshots.

App tester from India

As you can tell, an app tester has an extensive and time-consuming task. App developers with small budgets due to cost savings like to use Indian app testers as outsourcing professionals.

outsourcing4work can provide you with an experienced app tester from India who will help make your app a success. Depending on your requirements, you can hire an app tester at a fixed price (if you know the specific amount of testing to be done) or as a temporary employee.

In terms of coordination and payment, we will take over this work. You can conclude the contract with us as a European company and trust in our own project managers who will ensure implementation according to your exact specifications.

If you are looking for a certified tester for your software project, you can easily find outsourcing professionals thanks to the ISTQB certification system. The International Software Testing Qualifications Board (ISTQB) offers the world’s most popular seal of approval.

The non-profit organisation has assessed software testers on various relevant qualifications with standardised testing procedures since 2002. The certificates, which are classed according to complexity, classify the ISTQB testers hierarchically in the categories Foundation CTFL, Advanced CTAL and Expert CTEL.

The tests are offered internationally and performed in licenced test facilities according to a uniform scheme. This guarantees a standard of quality across national borders. There are now over 400,000 ISTQB Certified Testers around the world, and every quarter 13,000 new ISTQB Testers join them. ISTQB is the world’s largest certification authority for software testers. It’s important to have a look at the knowledge required for each level to find the best suited certified tester.

What an ISTQB Certified Tester should know

With a tailored methodology and the right software testing tools for every software project, an ISTQB Certified Tester ensures that the software meets the desired specifications.

A Certified Tester will take over the following tasks:

  • Test management and test coordination
  • Cooperation with development and quality management
  • Creating test concepts and test specifications
  • Creating test cases and test scenarios for business and technical requirements
  • Performing and documenting integration, system and acceptance testing of test runs in the test levels
  • Acceptance of the software and hand over to productive operation.

The ISTQB offers tiered knowledge certification to set a standard of expertise for each level.

ISTQB Certified Testers at Foundation Level know the necessary basics such as software life cycle, statistical tests, test case design technique and usual test tools.

ISTQB Certified Testers at Advanced Level expand upon this knowledge and have to be able to demonstrate 18 months of practical experience in software projects.

An ISTQB Certified Tester at Expert Level has additional specific skills for building and managing test teams, as well as deeper knowledge in the technical design, improvement and automation of test routines.

The mix has to be right

A Certified Tester does not have to be a real software developer. However, they should have good basic knowledge of the programming languages, development environments, test tools and collaboration tools that are being used. Since it differs from project to project and from team to team, just focusing on the label ISTQB Tester will not be enough. It has much more to do with additional qualifications that help in selecting a software tester.

Once you have exactly defined the knowledge profile, you can look for a Certified Tester in India. In the country, which is well-known for its excellent IT experts, you can find an ISTQB Certified Tester at especially low rates.

At outsourcing4work we can help you in your search and will find you a highly-qualified ISTQB Certified Tester who will fit your needs exactly. You can hire them at a fixed price for a specific test task, or as a temporary employee for your team.

We won’t leave you on your own afterwards! We ensure optimal communication between all parties with our project managers who are experienced in Scrum/Agile, and efficient implementation of all test processes according to your exact instructions.

Software testers play an important role in software development. It is important to have knowledgeable software testers on your team in the development to ensure error-free and perfectly working software. These testers should work as closely to your development team as possible.

It is a huge mistake when companies compromise on the technical quality of the software tester, or don’t use software testers to their full potential. The best option is to outsource to a professional Indian software tester with many years of experience.

What a software tester should know

A good software tester will ensure that the code is programmed with the correct semantics, the performance complies with the requirements and the user experience is as close to the needs of the users as possible. They use test routines, tools and manual tests to guarantee it.

An experienced software tester will know the basics of the programming languages and the development environment used, and is trained in the use of appropriate tools. Mobile apps require different test routines than for web applications in HTML/PHP, or Windows applications developed with .NET.

If you are looking for a software tester, then you have surely heard of the relevant test tools for your niche. The infoportal Testtool Review maintains an extensive, searchable database where you might find additional interesting test tools. From test automation, test management and error and change management, up to test specification, load and performance test, continuous integration to code and coverage analysis – you will find around 150 tools for nearly everything possible. Since the manufacturers and distributors of the test software update the records themselves, Testtool Review is certainly a good starting point.

In addition to this knowledge, certification from the Software Testing Qualifications Board (ISTQB) will also let you be sure that the software tester is experienced in the general methods, and will know what to do in test scenarios.

And finally, just like in other job, professional references are a great way to learn about the software tester. These not only show the software tester’s knowledge, but also their teamwork ability and their professionalism. Since efficient cooperation is especially important for an Indian software tester who will be working over distance, experience with Scrum – Workflows and collaboration tools pays off.

India is full of professionals

An Indian software tester with years of experience is usually much more affordable than a European junior software developer. Using such experts in software development will lead to an increase in quality, as well as cost savings.

outsourcing4work can provide you with an Indian software tester from India who you can hire for a fixed price for specific test work, or as a temporary employee in your team. We ensure optimal communication between all parties with our project managers who are experienced in Scrum/Agile, and efficient implementation of all test processes according to your exact instructions. 

Game testers are an important part of game development, especially for very large game titles which are extremely complex and have many different game modes, menus, options and possibilities.

Game testers find logic errors in game design, graphic bugs, performance problems, unexpected crashes, hardware incompatibilities, linguistic errors in translation and language output and much more – it is a long list of potential vulnerabilities in computer games. Unlike with other types of software, the testing process in computer games is not necessarily automated, and therefore requires a great deal of experience as a gamer, in addition to having a good eye.

Requirements for game testers

Usually only experienced gamers with hundreds or thousands of hours of gaming history are taken on as a game tester. A game tester’s experience plays a huge role, much more so than any formal qualifications or certifications. If a candidate already has experience working as a game tester for titles of the same genre, this is an excellent sign.

If they only have a few skills as a game tester, it’s still relatively simple to learn how to use the testing tools and documentation tools needed for the job.

A must for successful game tests are thought-out test instructions and the efficient use productivity tools to be able to have the results in an easily evaluable format later. A game tester has to play the game through normally in as many ways as possible, and test all the various missions, campaigns, roles, behaviour patterns and levels in each game, and document any irregularities in a specific format.

Game testers from India are more affordable

To receive feedback that is as realistic as possible, game testers are often employed as external employees or freelancers on a project basis. The entire exchange with the client usually takes place online and is not bound to a specific location.

This makes hiring offshore game testers from India especially interesting as these testers will only charge a fraction of the price that is normal in Europe. The cost advantage then makes it possible to conduct tests that are much more comprehensive for the same budget, and which would not be possible in Europe. At the end you then receive a successful and optimised project.

If you are looking for a professional game tester, outsourcing4work can help you further with temporary employees. We are specialised in providing Indian IT professionals and will easily find you the right game tester for your title.

If you leave the language-relevant tests/corrections in Europe, and outsource the rest of the test tasks to India, you will not need to worry about the language barrier at all. With our project managers who are specialised in Scrum, we ensure implementation according to your exact wishes. Our many years of experience in coordinating outsourcing employees play a large role. Legal security has also been taken care of – you conclude the contract directly with us as a European company. We will take care of the rest.

Code review is an essential part of software development for optimised and trouble-free source code. When writing program code there will almost always be errors that can only be found with additional controls through specific software testing.

Once the first code review has been done by the responsible developer themselves, an additional assessment by one or more testers is recommended since there are often many more errors to be found. Extensive studies show that between 20 and 60 percent of all expected errors in the development phase can be purged with a well-conducted code review.

This is much cheaper than if you wait until the alpha or beta phase to identify the errors, because at this stage the software project is already very far advanced.

A code review finds these standard errors

A tester in charge of a code review will test the written code with a mix of automated tools and manual review. Special software tools do not only find specific errors, but also help identify any problematic areas in the often very extensive code. These can then be closely looked at.

Typical vulnerabilities or deviations that can be discovered through a code review include violations of the naming conventions in the programming language, requirements that are not met or incorrect/contradictory requirements, design mistakes, vulnerabilities in the maintainability of the software or incorrect interface specifications.

So that the code is easy to understand for other developers, as well as for the further development of the software, the quality of the code comments also plays a role. If the code review is done by one or more external testers, there is almost always an improvement in the comments by exchanging them with the responsible developer.

Important tools for code review

Professional integrated development environments (IDE) such as Eclipse and Microsoft Visual Studio often come with different plugins for code review. The tester in charge of the code review should therefore be experienced in the IDE used by the team, as well as the language. In addition, there are popular tools for code review, in addition to the various platforms and version control software (VCS):

  • Crucible: Java – CVS, Subversion, Git, Mercurial, Perforce
  • Gerrit: Java EE- Git
  • Upsource: Java – Git, Subversion, Mercurial, Perforce
  • GitLab: Ruby on Rails – Git
  • Kallithea: Python – Git, Mercurial
  • Pabricator: PHP – Git, Subversion, Mercurial
  • Review Board: Python; Java: CVS, Subversion, Git, Mercurial, Bazaar, Perforce, ClearCase, Plastic SCM
  • Rietveld: Python – Git, Subversion, Mercurial, Perforce, CVS
  • Understand: Windows; Mac, OSX, Linux: popular control software

Indian software testers for code review

You can find a suitable expert for all of the review applications mentioned above relatively easily, even outside of Europe. Indian software professionals are excellent for especially intensive code review, as well as for cost savings. Thanks to the significantly lower rates in India the right professional can often conduct the code review process at a fraction of the costs. Or, for the same budget, you can hire multiple code reviewers, which will understandably improve the code quality.

outsourcing4work can provide you with the appropriate professionals from India who are experienced in the software tools used by you. Code reviews can be done at specific times as projects at a fixed price, or on hourly billing. We will not only ensure problem-free communication between the code reviewer and the development team with our own project managers, but we also guarantee proper implementation. You conclude the contract directly with us as a European company.

ISTQB Certified Testers can provide their expertise in software testing through a globally recognised certification process. The International Software Testing Qualifications Board (ISTQB) offers a range of various certificates depending on experience and expertise to verified knowledge through standardised testing.

ISTQB Certified Tester as a label of quality has caught on all over the world and is now often seen in job advertisements listed under the requirements. But what exactly should an ISTQB Certified Tester be able to do?

Basics for every ISTQB Certified Tester

With a tailored methodology and the right software testing tools for every software project, ISTQB Certified Testers ensure that the software meets the desired specifications.

They will check that programs run error-free and that the program code, languages, libraries and APIs interact successfully on the target hardware. While the main focus is on software bugs, aspects such as the proper function of the interface also play an important role.

An experienced ISTQB Certified Tester is able to design scenarios and appropriate test cases for test concepts and test specifications. They work very closely together with the responsible software developers, and in particular with the respective project manager.

Because ISTQB offers several different certifications graded on the level of knowledge, you should know the difference between them before choosing an ISTQB Certified Tester.

ISTQB Certified Tester at Foundation Level

The Foundation Level is the entry point for a ISTQB Certified Tester. They have the fundamentals such as the software life cycle, statistical tests, test case design processes and the popular test tools. Because knowledge is purely theoretical, an ISTQB Certified Testers at the Foundation Level should therefore already have good experience in software development so they can put their knowledge to use.

ISTQB Certified Tester at Advanced Level

Now is when it gets interesting with this level of certification. It builds on the foundation level and requires a minimum of 18 months’ practical experience in software projects. Existing knowledge is deepened and the participants are introduced to the tasks of a test manager.

ISTQB Certified Tester at Expert Level

The software tester will have additional specific skills for building and managing test teams. An in-depth knowledge of technical design and the improvement and automation of test routines is also part of an ISTQB Certified Tester’s role. This can be an especially large advantage in smaller developer teams with only one software tester.

Software tester as an outsourcing professionals

You can easily find an experienced software tester abroad with the quality assurance from ISTQB. If you would like to add an ISTQB Certified Tester to your team as a virtual team member, you should make sure they have already reached the advanced level. If they will be working completely independently as a software tester, then it might even be recommended to use one at the Expert Level.

The knowledge represented by ISTQB are ideally combined with many years of experience in software development, of course, in addition to at least a basic know-how in programming languages and software frameworks that are being used.

Once you know what the profile of the ISTQB Certified Tester should include, it is often easy to find the suitable outsourcing professionals from India who are also familiar with Scrum project management.

Outsourcing4work is specialised in providing Indian IT professionals and can take over the recruiting and even the subsequent coordination for you. We employ our own Scrum project managers who are well-versed in the online management of offshore freelancers. The contracts are concluded directly with us as a European company for your security and convenience. We have various contract models for fixed price projects or for services billed hourly. We can make a suitable offer for every project!

A website tester is specialised in testing web applications, and even ordinary websites, with various tools, and putting them through their paces. It is absolutely essential for professional results that experienced web developers and test users discover any vulnerabilities and errors in web applications. And this is not just by simply clicking the mouse.

Website testers use test scenarios and tools

Cross-browser testing tools are a part of the standard toolbox of a website tester. They are used to automatically check for compatibility with various web browsers and to test each version. With automatic layout analysis, detailed reports and screenshots created per browser view, problems can be quickly located and resolved.

Correct HTML code is essential for the proper presentation in different browsers. Special HTML validation tools are used by website testers to find inconsistent HTML code. These include Total Validator, Site Validator or RealValidator.

Other tools simulate user behaviour through mouse and keyboard entries and let complex test series be defined and played with the click of a mouse. This has the advantage that it makes exactly the same entries which are essential for finding errors. Tools such as Ghost Inspector, EveryStep or SlimerJS do a lot of work for the website tester by documenting the results appropriately with the help of automatically generated screenshots.

Load and performance tests play an important role for websites and apps which have high traffic on the server infrastructure. Load Complete, Multi-Mechanize, Load2Test and other similar tools simulates parallel access from thousands of users and evaluates it at the same time. Any vulnerabilities can be traced specifically by various types of simulated devices and screen sizes.

In addition to the tools set up to test pure functionality, there are also a number of automated security tests that a website tester can use to find any gaps and vulnerabilities. This aspect is becoming more and more important in these times of escalating cybercrime. Often website owners do not pay enough attention to this until the first website attack, although adequate safety testing by qualified employees does not cost much.

The advantages of an external website tester

Specialised website testers often have a large box of various test tools, including commercial products with extended functionality. Companies that conduct website tests in-house often don’t have the comparable test equipment, and have less experience as well.

Unfortunately, it is not unheard of that website developers take on the task of website testing, even though they do not have the same experience as an experienced website tester. A website tester does this job day in and day out, without doing anything else.

Then you have the cost benefits of an external website tester, especially in countries such as India where the salaries are just a fraction of what they are in Europe.

Website tests are great for outsourcing , since testers can work very well on their own once the test procedure has been established. The subsequent reports can be exchanged online and can be discussed via a video conference.

outsourcing4work can provide you with qualified website testers from India who will thoroughly test your web applications and/or websites with professional tools. We are not purely a provider, but also guarantee proper implementation with our own project managers. No bureaucratic uncertainties will arise, as you complete the contract directly with us as a European company. You can complete a project at a fixed price, or hire an Indian website tester as a temporary employee, depending on your needs.

Software testing is an important part in software development and is essential for high-quality results. Bugs and technical pitfalls are to be expected when developing software and can only be found and eliminated through extensive software testing.

Main functions of software testing

Software testing is done with a target/actual comparison to see if the software satisfies the requirements. The following questions play a main role:

  • Does the software meet the functional requirements through the proper semantics?
  • Does the software work with the desired performance or only under laboratory conditions?
  • Does the user experience meet the needs of the users?

To be able to answer these questions, software testing usually includes two different approaches during the development process. In software that is developed according to the waterfall or v model, software testing only comes to fruition after completing individual parts or artifacts. The errors will then be patched if necessary.

Modern software development is increasingly relying upon Scrum/Agile approaches which allows software testing earlier in the process because the individual tasks and results are described here in detail. Appropriate test scenarios are developed in parallel to the development work with a test first approach.

The typical problems or error sources that are found and eliminated during software testing are similar in the two approaches. Often disagreements with specifications, redundancies and mathematical mistakes or the complex interplay of modules which are not optimally coordinated are to blame.

So-called black box software testing then comes into play, in which only the output or results are tested. White box testing tests the programming code itself for errors with automatic tools.

Requirements for software testing

There is a vast diversity of programming languages, as well as the applications they can create. This will also affect the requirements of a software tester. A wide range of test tools is used to systematically test from the program code up to the manual handling on the keyboard and mouse.

The infoportal Test Tool Review, which specialises in software testing, has a long list of software test tools in a searchable database. From test automation, test management and error and change management, up to test specification, load and performance test, continuous integration to code and coverage analysis – you will find around 150 tools for nearly everything. The manufacturers and distributors ensure that the data of the tools remains current.

When selecting a software tester you should pay attention to make sure they have a comprehensive knowledge of the necessary test tools. In addition, certifications such as those from the International Software Testing Qualifications Board (ISTQB) prove that a software tester is able to handle unknown test scenarios and has sufficient test experience.

You will find testing professionals at the ISTQB expert level who are very experienced in creating and leading test teams, in addition to designing, improving and automatising test routines.

Software testing: outsourcing to India

Developer teams like to outsource tasks that are easily standardised. This is especially useful if there is not enough staff or time, which might endanger the proper implementation of the software testing.

You can find software developers with extensive testing experience at much lower rates in India than software testers in Europe who do not have any development experience. Using such experts in software development will lead to an increase in quality, as well as cost savings.

outsourcing4work can provide you with an experienced software tester from India if needed. Just share your specific needs with us and we will take care of the rest. Thanks to our project managers who are trained in Scrum/Agile, we ensure that no problems will arise during software testing.
