Codecoverage in codeception uses the C3 helper script that needs to be included in the site running. This collects code coverage even (especially) for acceptance tests, e.g. where codeception itself does not have control over the code. For coverage collection in general, XDebug is needed and therefore also activated. Production usage not yet possible due to https://github.com/Codeception/Codeception/issues/3337 also coverage collection is pretty slow.
