I have recently updated from PHPUnit 6 to 7 and running test suites now triggers the following warning:

PHPUnit 7.2.7 by Sebastian Bergmann and contributors.

  Warning - The configuration file did not pass validation!
  The following problems have been detected:

  Line 36:
  - Element 'log', attribute 'type': [facet 'enumeration'] The value 'coverage-php' is not an element of the set {'coverage-html', 'coverage-text', 'coverage-clover', 'coverage-crap4j', 'coverage-xml', 'json', 'plain', 'tap', 'teamcity', 'junit', 'testdox-html', 'testdox-text', 'testdox-xml'}.
  - Element 'log', attribute 'type': 'coverage-php' is not a valid value of the local atomic type.

  Test results may not be as expected.

Here is the relevant part of the phpunit.xml.dist:

    <logging>
        <log type="coverage-html" target="build/html-coverage-unit" lowUpperBound="35" highLowerBound="70" />
        <log type="coverage-php" target="build/clover-unit.cov"/>
        <log type="junit" target="build/junit.xml"/>
    </logging>

It seems the coverage-php is no more allowed by the xml schema. Is there any thing I missed when migrating? I searched but so far found no information about changes in this feature. However, despite the warning, the coverage is still generated without problem.

(I'm not sure about the location of this issue, maybe I need to open it on php-code-coverage? It seemed to me it was related to the general phpunit config file)

Thank you
