It is very important to know how well your application is tested. If you wrote all the tests by yourself, then you can probably guess it, but if there is a team or you are working on a relatively old project, guessing will not work.

This report gives information about how well the application is tested, which lines are being executed while running tests, and which are not.
As an example, we will generate a report for the Yii framework's core base classes.

cd path/to/code/tests/ phpunit --coverage-html report framework/baseAfter the report is generated, go to the
