Top 17 Functional Testing Companies In the USA

Functional testing can be defined as a quality assurance process. It is one of the types of black-box testing. Its test cases are based on the specifications of the software component being tested. Functions are evaluated by providing them input and assessing the output. The internal program structure is hardly taken into consideration (unlike white-box testing). Functional testing is done to assess the systems’ or components’ compliance with particular functional needs. The requirement of a functional test is increasing day by day.

Therefore, keeping this scenario in mind, we are presenting to you the list of the top 17 functional testing companies in the US.
