What is What is

QA?

Quality assurances (QA), is a set of activities aimed at ensuring and managing the highest product quality through scheduled and systematic actions. QA methods are focused on preventing software defects. The purpose of applying QA during the control of ongoing projects is to ensure that the used approaches, tools, techniques and processes are properly selected and followed. All activities related to QC are primarily aimed at monitoring and verifying subsequent stages of the product development process in terms of meeting defined quality standards. It is worth noting that all team members, not only testers, take responsibility for QA.

What does What does

The testing consist of?

Software testing is an integral part of the process of creating dedicated IT solutions. Its purpose is to verify the correct operation of the software and, above all, to verify whether the software's performance leads to the achievement of the expected outcomes. Testing yields better results if it is performed on many levels, throughout the whole process of software development.


There are many definitions and methods of software testing. Each type and level of software diagnosis can be treated as a separate testing sector. Proper methods are selected and applied depending on many different factors, such as project requirements, resources, time, usability, project structure, and, most importantly, budget.

Manual testing, as the name suggests, involves manual, human testing and hence is universal. This method is based on human resources (no programming skills required). Its advantage is that the manual approach allows more accurate observation and assessment of the performance of the tested software.

Manual testing is very suitable, for example, for exploratory testing (also called ad-hoc testing, based on the human factor, i.e. the tester's experience and intuition) and usability testing (aimed at assessing the user-friendliness of the tested software).

Automated testing is performed with the use of available tools and scripts, making it reliable and more accurate than manual testing. The results are automatically registered and available from the system level. This type of testing is performed in a shorter time, thanks to repetitive actions. It is a so-called regressive method, requiring no intervention of the manual tester. Another advantage of this method is that saving time almost always goes hand in hand with saving money.

Automated testing is certainly a productivity booster, providing fast and accurate results. Thanks to their repeatability and human error resistance, they are more reliable. They prove themselves in, for instance, performance and load testing.

However, automated testing surely will never replace manual testing. For a project to be prepared reliably both kinds of testing are indispensable. Both methods have their advantages and disadvantages. In practice, it is worth using automated testing where it is cost-effective and manual when necessary. Both of these methods are required, and their joint use is a guarantee of efficient and optimal software testing.

Functional testing of web and mobile applications (also called black-box testing) is an activity where the tester does not know the structure and operation of the application they are testing. This method consists in exploiting the given software and reporting irregularities appearing during its operation, i.e. simply checking the way the application works from a functional point of view.

Functional tests of an application allow monitoring not only the proper performance of a given function but also the user interface, user-server communication and available security features. Through all the above-mentioned activities, it is possible to provide a practical assessment of system operation under various conditions and circumstances.

Similarly to other methodologies, functional testing focuses on detecting and analysing errors in software operations. It is worth mentioning that these tests are not limited only to the diagnosis of abnormalities, but they also make it possible to determine the causes of their occurrence. To sum up, one can say that the main objective of this method is to assess to what extent the application is conducive to achieving business goals.

Performance testing consists of all actions aimed at loading the IT system following a pre-defined usage scenario (including for instance creating an account, navigating the application, browsing the forum or testing the search engine) by generating virtual users acting in line with the scenario.

Such tests allow the identification of critical points of the system, i.e. points which have a negative impact on the performance of the final product. Performance testing should be conducted in companies that use, or plan to launch, large-scale systems (e.g. online shops of retail chains and the applications or gaming platforms that support them).

This type of testing is recommended before implementing significant modifications of the IT system, primarily aimed at improving its functionality, e.g. through infrastructure reconfiguration or implementation of new software.

Performance testing can be divided according to the size of the load involved, as well as the purpose for which it was carried out. We divide such tests into the following categories:

  • Performance testing - this is the basic type of testing, which consists of checking whether the system under a defined production load will efficiently carry out its tasks;

  • load testing - testing of system capacity assuming a large number of simultaneous users or transactions in a given time;

  • Stress testing - deliberate overloading of the system aimed at testing whether the system operates in an expected manner and does not cause impairments, e.g. loss of data integrity;

  • scalability (capacity testing) - a gradual increase of the system load until bottlenecks are revealed;

As a result of performance testing, we can assess:

  • efficiency and speed of the performance of the system with its designed load;

  • system capacity, i.e. maximum load it can carry under current conditions (taking into account existing resources, architecture and acceptable response time);

  • stability of operation under system overload;

  • scalability of the system.

Thanks to performance testing, we can also identify bottlenecks, i.e. factors that limit the system's performance and ways of eliminating them (e.g. improving the source code, increasing resources or changing the architecture).

Within the framework of all testing we offer, our goal is to find the so-called planes of increased risk and imperfections occurring in the tested system. We identify possible vulnerabilities, missing elements or errors not only concerning the software functionality but also to the defined project requirements. Furthermore, we offer the support of the QA team even after the completion of the project as well as the availability of cooperation within the framework of further development.


Our team of specialists can identify the weakest points in the process of computerisation of your company and show you how to fix them, thus increasing the security level of your data. We, at all times, analyse projects in terms of usability, efficiency and security. Moreover, we help you optimise your processes, of course, while maintaining the highest quality.
