Types of our software testing

It is equally important to perform non-functional testing in addition to functional testing. To ensure that teams are conducting a mix of different types of testing, both types of testing must be completed during the quality assurance services complex. That is essential to having QA and testing services work just as expected.

  • Functional testing

    As a type of software testing, functional testing involves validating the software system against its functional specifications. Tests are performed to ensure software functions are working as intended by giving adequate input and comparing the received result with the requirements.

  • Non-functional testing

    Software non-functional testing examines the non-functional features of a software application (performance, usability, dependability, and so on). The non-functional test aims to assess a system's readiness based on criteria that never appear in functional tests.

Our QA services lifecycle

With decades of QA experience, we know precisely the best way to start our future cooperation. Meet our QA as a service lifecycle:

Quality assurance & testing services start with your project documentation audit to know your key goals and features from top to bottom and prepare the perfect test plan considering all your essential needs.

We will identify test situations, create the most common test cases, and define the test starting point, completing our test scenario. Developing a piece-of-mind testing automation if you require it.

During the implementation stage, functional and non-functional testing is performed. Following the test cases established, errors are discovered and reported. QA ensures that the features are constructed and work in line with the requirements supplied.

Our team completes the full regression test to exclude any script sabotage and be 100% sure that everything is nice and steady.

After the successful acceptance testing and scope verification, our QA team provides the final test results and performance review with detailed information about criticals and deliverables.

Client feedback


Ich war am meisten von der Qualität des Endprodukts beeindruckt.

Während meine Ideen die Grundlage für die Arbeit bildeten, lieferten sie ein weit überlegeneres Produkt als ich es mir vorgestellt hatte, mit größerer Flexibilität und Lebensfähigkeit der Funktionen. Sie übertrafen die Erwartungen so oft, dass ich kaum erwarten konnte, zu sehen, was sie als Nächstes entwickelten.
