What is Code Coverage?

Code Coverage is a White Box Testing technique used to determine lines of code successfully validated.It helps to determine which lines of code are never executed.It is a dynamic white box testing as access to the code is made available.

The different types of Code Coverage analysis includes :

1.Statement Coverage.

2.Branch Coverage.

3.Condition Coverage.

1.Statement Coverage :

The most simplest form of code coverage is statement coverage or line coverage.Here we ensure that every statement is executed at least once during testing.100% statement coverage can be misleading at times as it does not ensure that your program is tested completely.

2.Branch Coverage :

It is also called as Path Testing.Here we try to cover all the paths in the software to ensure the program is tested completely.

3.Condition Coverage :

Condition coverage takes into account multiple conditions to be tested to ensure that the program is tested completely.

 The different code coverage tools are :

1.CodeCover.

2.OpenCover

3.JCov

4.EMMA
