Types of functional testing
What is functional testing? It is a type of software testing technique that checks a certain system against functional specifications. Its main goal is to test whether the system corresponds to all requirements and produces favorable results. There are a few types of functional tests to use in different circumstances. The first one is unit testing, performed by developers, this tests each part of the code and focuses on the smallest units. Then component testing – testers check each object independently. Integration testing is applied to check how well individual components can function together. Smoke testing is said to be one of the most important types, as it verifies whether the basic functionality is working fine. Then follows sanity testing, with the help of which we can be sure that all the issues were fixed and there are no new bugs.

And the last stage of the software development process is user acceptance testing, performed by the customer to see if the product meets their expectation. Read the full article
