V Model

V Model

For every development phase there is a corresponding testing phase. This is known as V-Model

1)   Unit Testing:

The objective of Unit Testing is to isolate a section of code and verify its correctness. In procedural programming a unit may be an individual function or procedure

2) Integration testing:

In integration Testing, individual software modules are integrated logically and tested as a group.

A typical software project consists of multiple software modules, coded by different programmers.

3) System testing:

System Testing is the testing of a complete and fully integrated software product. Usually software is only one element of a larger computer based system. Ultimately, software is interfaced with other software/hardware systems.System Testing is actually a series of different tests whose sole purpose is to exercise the full computer based system.
