The most commonly used software testing techniques include acceptance testing, system testing, integration testing and unit testing. The order in which software testing takes place is listed below.
Unit Testing – It is the first step involved in the process. Individual components of software are tested for errors. It is important for you to know the details of programming as every module is checked. Therefore, Unit Testing is performed by programmers and not testers.
Integration Testing – Individual modules that have already been tested are integrated with each other, and tested for errors. This form of testing underlines interfacing errors. There are two approaches for performing it – “bottom-down’ approach and “top down approach”.
System Testing – In this stage of testing, the entire product is tested for bugs as well as errors. This test is performed by interfacing software as well as hardware components of the system. The testing is categorised as black box testing method and here the software is tested to ensure that is user friendly enough to be used by users.
Acceptance Testing – This is the last testing methodology that is done prior to handling the software to the client. It ensures that software developed is up to the expectations of the client. Acceptance testing is of two types – Beta Testing and Alpha Testing.
