Functional testing, on the other hand, checks the functionalities of the app minus looking at the code’s internal structure and thus it is called the black box testing. Despite how flawless is the different code components, it is important to check whether the application is functional as you have expected it to be if all the components are integrated.
Kinds of Functional Testing
The different kinds of functional testing are stated in our Functional Testing case study help online as follows:
Sanity Testing: It is done when the testers do not have adequate time to test. This is a surface level testing wherein QA engineers verify that the functions, menus, and commands are available in a product.
Smoke Testing: It is a type of software testing that is done after the software is created for ascertaining that the important functionalities of a program are doing fine. This is performed before the detailed regression or functional tests are done. The basic purpose is rejecting a broken application so that time is not wasted to test and install the software application.
Regression Tests: In this test, the test cases are re-executed for checking whether the earlier functionality has been working fine and there are no bugs in the new changes. The test may be done on the newly created program or code snippet if there is a massive change in the primary functionality.
Integration Tests: A common use of integration testing is after unit testing. The unit shall be tested and then integrated with the surrounding units. Integration testing is performed for verifying the functionality between the components and not retesting each combination of the functionality of the lower-level.
Usability/Beta Testing: Usability testing confirms whether this works properly for other users. It is generally the last step before the software/feature goes live. This test ensures that the software meets the user needs.
