I'm getting empty results when I use phpcov on the output from this extension:

Code Coverage Report:  
  2018-07-17 01:57:32  
                       
 Summary:              
  Classes:        (0/0)
  Methods:        (0/0)
  Lines:          (0/0)

The .cov file is 118K and starts like:

<?php return unserialize('O:43:"SebastianBergmann\\CodeCoverage\\CodeCoverage":20:{s:51:"' . "\0" . 'SebastianBergmann\\CodeCoverage\\CodeCoverage' . "\0" . 'driver";O:44:"SebastianBergmann\\CodeCoverage\\Driver\\Xdebug":1:{s:59:"' . "\0" . 

So it seems to be the right thing. But I notice when it gets included in SebastianBergmann\PHPCOV\MergeCommand, the resulting object doesn't have anything in the data array.

When PHPUnit runs and fails to find a code coverage driver (xdebug) it tells you and continues with the tests anyway. I just doesn't generate the coverage reports. This is pretty good as it simplifies our phpunit config and means we can choose to run with or without coverage by simply not enabling xdebug on that container run.

But this extension fails hard if a coverage driver cannot be found. Ideally it would provide for the same behaviour as PHPUnit.

PHPunit, on a test suite that provides 100% coverage of a class gives me

Behat coverage, with a suite which I think gives 100% coverage gives me

or (different method but similar code)

The switch case lines are always ignored by phpunit, but intermittently covered by behat-local-code-coverage. I've had a rummage through both PHPunit and this extensions implementation of the CodeCoverage library and they both call in very similar ways. So I have no realy idea why they're behaving differently.

The only difference in the coverage files that I can see is that a PHPUnit file does not have any $ignoredLines when debugging. This extension produces files with $ignoredLines populated.
