The main focus of black box testing is on the validation of your functional requirements. Regression testing – Regression Testing is done after code fixes, upgrades or any other system maintenance to check the new code has not affected the existing code.Ĭomparison of Black Box and White Box Testing:.Non-functional testing – This type of black box testing is not related to testing of specific functionality, but non-functional requirements such as performance, scalability, usability.Functional testing – This black box testing type is related to the functional requirements of a system it is done by software testers.There are many types of Black Box Testing but the following are the prominent ones – There is a unique combination in each column.

Boundary Value Testing: Boundary value testing is focused on the values at boundaries.Equivalence Class Testing: It is used to minimize the number of possible test cases to an optimum level while maintains reasonable test coverage.Black Box Testing and Software Development Life Cycle (SDLC)Ĭlick here if the video is not accessibleįollowing are the prominent Test Strategy amongst the many used in Black box Testing.Comparison of Black Box and White Box Testing:.How to do BlackBox Testing in Software Engineering.
