-#### Code Coverage (PHP engine only)
-
-The API tests also support code coverage tests. You need to install
-[PHP_CodeCoverage](https://github.com/sebastianbergmann/php-code-coverage).
-On Debian/Ubuntu run:
-
-    apt-get install php-codecoverage php-xdebug

-Then run the API tests as follows:
-
-    behave api -DPHPCOV=<coverage output dir>
-
-The output directory must be an absolute path. To generate reports, you can use
-the [phpcov](https://github.com/sebastianbergmann/phpcov) tool:
-
-    phpcov merge --html=<report output dir> <coverage output dir>
