PHPUnit is not producing its clover coverage report
It seems like you didn't define a whitelist. Without any whitelist, no coverage data will be produced in PHPUnit 5. Try something like:
<phpunit bootstrap="./test/bootstrap.php" colors="true"> <testsuites> <testsuite name="Tests"> <directory>./test</directory> </testsuite> </testsuites> <filter> <whitelist addUncoveredFilesFromWhitelist="true"> <directory>./lib</directory> </whitelist> </filter></phpunit>
There are some issues if several versions of phpunit are available on the system.
