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

The QA team has been a great help for the release of our new offering, Unfold for Brands. The team has really put themselves in the place of the user to find any bugs or user experience issues, mitigating any potential issues at launch.
