Recently, I wrote some for a project and realized that I wasn't aware of how to generate code coverage reports. Many thanks to the very helpful patrons in the #pear channel on EFNet for helping me to get this working.

He show his setup process (on Kubuntu) - grabbing the PEAR package, installing it and how to get a runner script to integrate the PHPT testing into PHPUnit.

So this evening I managed to get PHPT running my tests (they're just basic .phpt tests but run-tests is..well flakey is a nice description some days) for my winapi php extension wrapped inside a "generic test" for Visual Studio. [...] So what did all this accomplish? I now can run my phpt tests through visual studio and collect code coverage on what they’re testing. Like GCOV, only for windows.

She's also included a screenshot of what the interface and results of the testing look like in the latest Visual Studio tool.
