merging coverage files generated with codeception

[jcheron]

Problem:

I use codeception for acceptance (with Selenium) and local unit tests.
I want to merge remote coverage with local.
The 2 generated reports make references to the same files (identical paths and namespaces), however, codeception does not merge them.

So I'm trying to use phpcov...

I use the --coverage option to produce serialized format files

codecept run --coverage

The 2 generated files are:

• coverage.serialized in the _output local folder
• codecoverage.serializedin the _output/c3tmp remote folder on the web server
  I copy the remote file in the same folder (tests/_output) that the local and execute:

./vendor/bin/phpcov merge tests/_output/ --clover tests/_output/coverage-all.xml

Console output:

phpcov 5.0.0 by Sebastian Bergmann.
Generating code coverage report in Clover XML format ... done

No error, but the generated file is empty:

<?xml version="1.0" encoding="UTF-8"?>
<coverage generated="1548805986">
  <project timestamp="1548805986">
    <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>
</coverage>

phpcov is it compatible with codeception and the serialized format as some say? see Codeception/Codeception#3245 (comment)

Hello,

I didn't use codeception at all, so maybe my comment is not relevant.
Did you configure a whitelist somewhere?

If there is nothing configured as whitelist, everything will be filtered.
For example, with phpunit, you have to configure a whitelist this way in phpunit.xml:

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

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

There is also a whitelist with codeception:
in codeception.yml file:

coverage:
    include:
        - directoryToInclude/

but the problem was elsewhere.
I found the solution, see Codeception/Codeception#5368 (comment)

Thank you for your answer
