Every feature/function of a piece of software should be tested thoroughly before it's released, and many of them should be continually tested. The functional test cases are the documents written by QA managers for the purpose of conducting functional testing. Functional test cases inspect the software's functionality across a range of actions or conditions to ensure the desired outcome. Following are the features of a functional test case:
* Name or description of the function/feature.
* The preconditions for testing.
* The steps needed to test.
* The expected outcome/result.
All of these provide the tester with everything they need to satisfy the test case requirements. It is also a good idea to write the location of the function in the description section, especially if the app is very large and complex, or if the same function is found in some different areas of the app.
