Make sure your software works as intended.

When testing software, there are some primary types, such as functionality testing, that should be performed anyway. So let’s first understand what is functional testing and what its purpose. Every app contains a lot of features, and it’s very important to ensure bug-free operation, as sometimes even one bug can lead to large monetary losses. Being a major type of software testing, functional testing is used to verify that a particular feature of your product meets business or end-user requirements.

Our company provides top quality manual and automated functional testing for any platform: desktop, mobile or web. Based on the requirements claimed in the specification and business processes that the application should provide, we make sure that all app functions work correctly with various types of input data, their combinations, quantities, and that all operations performed correctly in terms of system usage scenarios. You can be sure that our testing services will help your product achieve perfect quality.

Functional Testing Types We Provide

There are several basic methods of functional testing in software testing. These tests are usually considered
self-sufficient in the search for errors and bugs throughout the system. QAwerk applies the appropriate testing method depending on the case.

Black-Box Testing

Black-box testing is carried out without any knowledge of the internal operation of the system. The tester stimulates the software for the user environment by providing various inputs and testing the generated outputs.

White-Box Testing

White-box testing, unlike the black box, takes into account the internal operation and logic of the code. To perform this test, the tester must have knowledge of the code in order to know the exact part of the code that has errors.

Gray-Box Testing

In gray-box testing, the tester has only the general knowledge of the product needed to perform the test. This verification is carried out through documentation and information flow schemes. Testing is carried out by the end-user, or users who are presented as end-users.

Integration testing

Sanity testing

System testing

Smoke testing

Interface testing

Regression testing

Beta/Acceptance testing

  • QAwerk’s efforts enabled internal developers to eliminate bugs and improve the app’s stability. Communicative and accommodating, the team proved capable of identifying technical errors.

  • We've worked with QAwerk to handle the QA of our native desktop app. They've done a tremendous job and even went out of their way to ensure the quality of the app. We'll continue working with them in the future.
