Coverage calculation issue

[dominikzogg]

Q	A
PHPUnit version	9.3.x
PHP version	7.4.9
Installation Method	Composer

Summary

The coverage calculation seem to have changed with phpunit 9.3.x.

phpdbg -qrr vendor/bin/phpunit --testsuite=Unit --coverage-text --coverage-clover=build/phpunit/clover.xml --coverage-html=build/phpunit/coverage-html --coverage-xml=build/phpunit/coverage-xml --log-junit=build/phpunit/junit.xml --cache-result-file=build/phpunit/result.cache

This leads to issue with infection testing: infection/infection#1289

Current behavior

The line is not marked as covered, even when it is. (Same code worked until 9.2.x)

How to reproduce

Source: https://github.com/chubbyphp/chubbyphp-framework-skeleton/blob/master/app/ServiceFactory/Framework/RoutesFactory.php
Test: https://github.com/chubbyphp/chubbyphp-framework-skeleton/blob/master/tests/Unit/ServiceFactory/Framework/RoutesFactoryTest.php

Run the test:

phpdbg -qrr vendor/bin/phpunit --coverage-html=coverage tests/Unit/ServiceFactory/Framework/RoutesFactoryTest.php

open coverage/ServiceFactory/Framework/RoutesFactory.php.html

Expected behavior

That the missing line is marked as covered.

A lot has changed in php-code-coverage ^9. For instance, we no longer work around bugs etc. in the extensions that are used to collect code coverage data. PHPDBG is not up to par with Xdebug or PCOV. I will not invest any time in debugging issues related to PHPDBG.

Do you experience the same problem with PCOV 1.0.6 or Xdebug 2.9.6?

@sebastianbergmann will test it and keep you updated, thanks for the response
