Coverage report run under docker reports incorrect source

[mcaulifn]

I am attempting to generate a coverage report for SonarQube. The project is built and tested using a container. The xml file has the source listed <source>/build/project</source> where as the actual files are under /data/jenkins/workspace/project/lambda. Is there a way to re-write the source when generating the report? python and libraries are not available outside the container as this is a Jenkins instance.

Did you try the aliasing options here https://coverage.readthedocs.io/en/v4.5.x/config.html#paths ?

[mcaulifn]

Yes, in the .coveragec file (/data/jenkins/workspace/project/lambda/), I put the following:

[paths]
source =
    project/
    /build/*

Nothing had changed in the report.

@ionelmc any update?

[ionelmc]

So you're generating the report outside the running container? That means you're not using pytest-cov for that. How is that a pytest-cov problem?

[mcaulifn]

the report is generated inside the container. it is not valid outside the container because the paths are different.

[ionelmc]

I'm afraid you need to have the sources in the actual path inside the container, unless I misunderstood how coveragepy works. Either way this ain't a bug in pytest-cov.

You could also apply a XSLT the the coverage.xml, in addition to mounting an extra path inside the cotainer.

@mcaulifn You should open an feature request against coverage.py: when it generates the XML report, it uses the filenames as it knows them. In your case, those are names inside the container.

I'm not sure how you would like coverage.py to know what the outside-names are for the files, but we can work that out.
