Tests are grouped together based on where they are added in SDLC or the by the level of of detailing they contain. In general, there are four levels of testing: unit testing, integration testing, system testing, and acceptance testing. The purpose of Levels of testing is to make software testing systematic and easily identify all possible test cases at a particular level. There are many different testing levels which help to check behavior and performance for software testing.

The purpose of Levels of testing is to make software testing systematic and easily identify all possible test cases at a particular level. There are many different testing levels which help to check behavior and performance for software testing. These testing levels are designed to recognize missing areas and reconciliation between the development lifecycle states. In SDLC models there are characterized phases such as requirement gathering, analysis, design, coding or execution, testing, and deployment. All these phases go through the process of software testing levels.
White box testing is the testing of the internal workings or code of a software application. In contrast, black box or System Testing is the opposite.
