What is Functional Testing?

One of the roles of QA is making sure that the software meets the requirements and is functioning correctly and that is called Functional Testing.

There are several types of functional testing and that includes:

• UAT - it is a type of testing performed by the end user/client to verify and accept the software system before moving the software application to the production environment.
• Exploratory Testing - Assess a product by learning about it through exploration and experimentation.
• Sanity Testing - it is a kind of Software Testing conduct after receiving a software build, with minor changes in code, or functionality, to assure that the bugs have been fixed and no further issues are introduced due to these changes.
• Regression Testing - it is a type of software testing to validate that a recent program or changes in the code has not adversely affected existing features.
• Smoke Testing - it is a software testing process that determines if the deployed software build is stable or not. Smoke testing is a confirmation for QA team to begin with further software testing. It include of a minimal set of tests run on each build to test software component.
• Integration Testing - type of testing where software modules are integrated logically and tested as a group. A typical software project consists of multiple software modules coded by different programmers. This testing level aims to expose defects in the interaction between these software modules when they are integrated.
• Unit testing - This low-level testing ensures smaller components are functionally sound while taking the burden off of higher-level tests.

QA Engineers elaborate the most suitable test strategy for each project combining best practices of functional testing, peculiarities of the project and the customer’s request. QA Engineers chooses the right functional testing tool depending on the type of applications you are testing, the testing requirements, and your testing environment.
