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.

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 atAdvanced Level expand upon this knowledge and have to be able to demonstrate 18 months of practical experience in software projects.
An ISTQB Certified Tester atExpert 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.
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):
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.

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.
