Executing merge command outputs empty coverage about phpcov HOT 4 CLOSED

Hello,

Did you configured the phpunit.xml with a whitelist?
I had the same problem, and after investigation, the files .cov had no data due to this missing configuration.

https://phpunit.readthedocs.io/en/7.4/code-coverage-analysis.html#whitelisting-files

    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">your_directory/</directory>
        </whitelist>
    </filter>

Hey thanks for the input.
Do you mean the .cov files used for merging? Because they do have content, (I attached them in my comment as phpcov1.txt because phpcov1.cov couldn't be uploaded).

I also tried adding a phpunit.xml with the filter and whitelist nodes to my root folder, but I still get the same empty output.

<?xml version="1.0" encoding="UTF-8"?>
<coverage generated="1549421579">
  <project timestamp="1549421579">
    <metrics files="0" loc="0" ncloc="0" classes="0" methods="0" coveredmethods="0" conditionals="0" coveredconditionals="0" statements="0" coveredstatements="0" elements="0" coveredelements="0"/>
  </project>

Thank you for your report.

Please provide a minimal, self-contained, reproducing test case that shows the problem you are reporting.

Without such a minimal, self-contained, reproducing test case I will not be able to investigate this issue.

Thank you. Actually, while trying to re-create the problem I noticed that the path values set in $filter->setWhitelistedFiles() inside the .serialized file were not matching to the actual test files. This was due to manually moving the files from another location.

$filter->setWhitelistedFiles(array (
  '/app/tool/files_to_merge/exampleTest.php' => true,
));

By keeping the files inside their directory (the one whitelisted in the phpunit.xml file) and running the command from there I could finally generate a correctly merged file.

Everything works as it should. Sorry for the trouble.
