No code coverage whereas it should have some

[b2p-fred]

In a fresh Docker container (alpine linux php-fpm 8.0) I executed the following commands :

# Install required packages
$ composer require --dev matthiasnoback/live-code-coverage
$ composer require --dev phpunit/phpcov

# Modify the main controller (see later)

# Run the behat tests
$ ./vendor/bin/behat features/core/Anonymous.feature

# List the coverage files
$ ls -al artifacts/live-coverage/
total 172

Code Coverage Report:     
  2022-02-16 13:15:40

  Methods:  0.00% (0/419) 
  Lines:    0.00% (0/1515)

With this procedure the tests results show no coverage at all !

Note that the problem that I encountered in #20 disappeared!

The application main controller:

<?php

use App\Kernel;
use LiveCodeCoverage\LiveCodeCoverage;

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    $shutDownCodeCoverage = LiveCodeCoverage::bootstrap(
        true,
        __DIR__.'/../artifacts/live-coverage',
        __DIR__.'/../phpunit.xml.dist'
    );

    // Run your web application now...
    $kernel = new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);

    // This will save and store collected coverage data:
    $shutDownCodeCoverage();

    return $kernel;
};

One of the .cov produced files (I do not know if it may help?) :

Could it be that phpunit.xml contains invalid configuration for what to include in/exclude from code coverage?

[b2p-fred]

Here is my phpunit.xml.dist file :

When I run my unit tests with phpunit, I get correct code coverage. Do you have some specific requirements for as phpunit configuration. I did not see any except having correct inclusions ...

[matthiasnoback]

Sorry, I have no idea what may be wrong here. I'd recommend step-debugging. Maybe something has changed here: https://github.com/matthiasnoback/live-code-coverage/blob/master/src/LiveCodeCoverage/CodeCoverageFactory.php This replicates part of PHPUnit itself, but maybe PHPUnit has diverged from this code.

I ran into the same problem, but I was able to solve it by adding the <filter> and <whitelist> tags to the phpunit.xml.dist file. I guess that the coverage whitelist filter is empty by default which means that none of the files would be covered. Here's my phpunit.xml.dist file for reference in case someone else will encounter the same issue.
