Is it possible to tell why a coverage report can't be parsed?

[BatmanAoD]

I'm trying to make sure that a CI job is generating a valid Cobertura file, but pycobertura show just says the file is invalid:

❯ pycobertura show ~/Downloads/cobertura-coverage.xml
Traceback (most recent call last):
  File "/Users/kstrand/.pyenv/versions/3.10.12/bin/pycobertura", line 8, in <module>
    sys.exit(pycobertura())

    return self.main(*args, **kwargs)
  File "/Users/kstrand/.pyenv/versions/3.10.12/lib/python3.10/site-packages/click/core.py", line 1078, in main
    rv = self.invoke(ctx)

    return _process_result(sub_ctx.command.invoke(sub_ctx))

    cobertura = Cobertura(
  File "/Users/kstrand/.pyenv/versions/3.10.12/lib/python3.10/site-packages/pycobertura/cobertura.py", line 67, in __init__
    raise self.InvalidCoverageReport("Invalid coverage file: {}".format(report))
pycobertura.cobertura.Cobertura.InvalidCoverageReport: Invalid coverage file: /Users/kstrand/Downloads/cobertura-coverage.xml

Is it possible to get more detail than this? I don't see a verbose option or anything like that.

I see your point. Pycobertura will try to read the coverage report in two ways:

• by treating the argument as an expected filename (most use cases when using the command line)
• by treating the argument as an XML input, e.g. <xml>...</xml> (may be more common when using pycobertura as a library)

In your case, it's from the command line, so it's likely that pycobertura just couldn't find the file on disk.

Would an output like this one be more useful?

pycobertura.cobertura.Cobertura.InvalidCoverageReport: Invalid coverage file: goobar.xml. The following exceptions occurred while attempting to parse the report:
* While treating the report as a filename: Error reading file 'goobar.xml': failed to load external entity "goobar.xml".
* While treating the report as an XML Cobertura string: Start tag expected, '<' not found, line 1, column 1 (<string>, line 1)

To be clear, should the file exist and still fail to load, the error would explain why it failed. Your feedback is integrated in #187.

Yes, that perfect; thank you.
