Software Testing Methods

Software Testing Methods can be broadly classified as Black Box Testing, White Box Testing & Gray Box Testing.

Black Box Testing: In this type of testing , the tester views the program as a black - box, tester doesn't see the code of the program: Equivalence partitioning, Boundary - value analysis, Error guessing are the few which user will consider when testing.

White Box Testing: In this type of testing , the tester examine the internal structure of the program: Statement coverage, Decision coverage, condition coverage, Decision/Condition coverage, Multiple - condition coverage. This to do more with code verification. Usually the development team does this type of testing as many a times QA will not get accessto the code written by the developer.

Gray Box Testing: In this type of testing Black box testing can be combined with knowledge of database validation, such as SQL for database query and adding/loading data sets to confirm functions, as well as query the database to confirm expected result.
