-> Please note that if you choose to use `--configuration`, `--filter`, or `--testsuite` for PHPUnit, these options will only be applied to the _initial_ test run. Each mutation has a custom `phpunit.xml` file generated for it which defines a single testsuite containing the tests which should be executed for that mutation. Applying `--filter` or `--testsuite` would not make sense in this context as the tests have already been filtered down.

 ### `--coverage`
 
 Path to the existing coverage reports.
 
-When you use Continuous Integration for your project, probably you are already generating code coverage metrics and run PHPUnit with `XDebug`/`phpdbg` enabled. Then, you run Infection for mutation testing, which in its turn, generates Code Coverage again for internal needs. This dramatically increases the build time because running your tests with debugger *twice* requires too much time.

 With this option it's possible to reuse already generated coverage in Infection.
