Add it to your composer.json file to install with Composer:

{
    "require" : {
        "henrikbjorn/phpspec-code-coverage" : "1.0@dev"
    }
}

$ composer update henrikbjorn/phpspec-code-coverage

Enable it in your phpspec.yml file:

extensions:
    - PhpSpec\Extension\CodeCoverageExtension

Now run your specs with the normal phpspec run and voila your code coverage will be available in coverage.

Configuration Options

It is possible to control a bit out how the code coverage is done through phpspec.yml. This is done by adding a code_coverage key which takes a hash of options.

• whitelist takes an array of directories to whitelist (default: lib, src).
• blacklist takes an array of directories to blacklist (default: test, spec, vendor).
• output takes a location relative to the place you are running phpspec run (default: coverage).
• format (optional) could be one of: clover, php, text, html (default html)
• show_uncovered_files for including uncovered files in coverage reports (default true)
• lower_upper_bound for coverage (default 35)
• high_lower_bound for coverage (default 70)
