Test coverage or code coverage is a term widely used in software testing services and is considered a part of software maintenance. It is a very useful tool that lets software testers identify untested areas of a code base. By providing data on different coverage items it helps in evaluating the effectiveness of testing.
Together with covering those areas that have not yet been tested, test coverage also helps to monitor and maintain the quality of testing. Measuring test coverage quantitatively will help to determine its quality, as they are indirectly related. It also helps to identify redundant test cases that prevent any increase in coverage thereby providing better software testing services.

Tools for Test coverage
The Test Coverage tools are useful as they can easily locate application functionalities and allows exercising the functionalities of interest. What part of the application code is executed will be indicated by the test coverage tool. This helps to easily locate functionality in a very effective manner, especially those in a large, difficult to understand system. Coverage tools help in checking how thoroughly testing has been done.
It is very important to know that achieving 100% statement coverage doesn’t mean that your software is completely tested and error free. This is because coverage tools can only measure the coverage for those items that they can identify. Coverage tools needs to be run often to look at these bits of untested code.
