# DESCRIPTION

`App::RaCoCo` provides the `racoco` application, which can be used to run tests and calculate code coverage.

You may specify the following parameters:
* **--lib** - path to directory with coverable source files (`'./lib'` by default);
* **--raku-bin-dir** - path to directory with raku and moar binaries (`$*EXECUTABLE.parent` by default);
* **--exec** - command, which need to be executed to run tests. For example, you may pass `'prove --exec raku'` to the `exec` parameter to say `prove` to manage your tests, or use `--/exec` parameter to not run tests and use coverage data from the previous run (`prove6` by default);
* **--fail-level** - integer number - if coverage will be less than it then `racoco` will exit with non-zero exitcode;
* **--silent** - hide test result output;
* **--append** - do not clean coverage data before this `racoco` run and append its result to the previous one;
* **--html** - produce simple html page to visualize results;
* **--color-blind** - addition to `--html` parameter - use more readable colors than green/red pare. 

# NOTE

RaCoCo application works only with MoarVM backended Raku compiler.
