PHP Code Coverage Verifier

PHP Code Coverage Verifier allows you to determine if a change you've just done to your PHP code is being tested/covered by your tests. It uses a clover-xml report from a phpunit run (or any other code coverage suite that outputs to clover-xml format) and a unified diff containing your changes. PHP Code Coverage Verifier will then generate a list of the covered and not covered changes.

Notice

The code is currently in a very crude state. It was done as a proof of concept and will improve if it proves useful to others.

How to use

PHP Code Coverage Verifier ships as a Composer package. You can include it in your project's composer.json and use in a console.

Before you run the command line, be sure to run your tests with phpunit (or other) and generate the clover xml file that will be used here. For instance, one can generate the clover-xml file with phpunit using phpunit --coverage-clover=my-clover.xml.

Then you need to generate the diff of your changes. Here we assume you will generate those using either svn diff or git diff (users of TortoiseGIT/TortoiseSVN can use "Create patch...").
