The error is just "Error: " so not very descriptive

[halkeye]

Okay, I figured out this is because the default format is not supported

py.test --cov=<mypackage>  --cov-report xml

i've been trying --add-prefix thingie, but passing my module directory and the full path to it doesn't seem to work

[halkeye]

okay, had to eventually run it without mypackage

py.test --cov=. --cov-report xml

Now things work, so it looks like <source> is ignored in the xml

[halkeye]

If i ran it with --cov=mypackage it has <package name="."> not the package name like

@halkeye A new release was made recently with the goal of addressing this issue https://github.com/codeclimate/test-reporter/blob/master/CHANGELOG.md#v032-2017-10-30. Let me know if you try and resolves the error you were having.

[halkeye]

awesome! I worked around the problem, but I'll try to get it tested with the new stuff asap.

I'm having an issue with this also. When running locally, all is fine. But I'm actually running my tests (pytest + pytest-cov) in a Docker container, so my <source> tag is pointing to something that doesn't exist on the host system (I'm running cc-test-reporter from the host). From the docs I would assume setting --prefix to fix this, but it doesn't seem to matter what I put there (I guess the value is overwritten by the coverage.py <source> parser?).

I can think of a few possible workarounds:

• remove <source> tag, and use --prefix (not sure if it will work at all?)
• run cc-test-reporter from the Docker container (will be very dirty, as I have to pass e.g. all the Travis env vars and deal with test exit code, and propagate it again after cc-test-reporter).
• replace <source> contents with the directory on the host system, using sed or something. I will go for this, as it seems to me a failsafe semi-clean workaround.

Edit: Third option did work. Actually, since I'm running coverage only for my source directory (e.g. <repo root>/my_app_source), I'm running pytest like this:

• pytest --cov=my_app_source --cov-report=xml To get CodeClimate to work properly, set <source> to this folder:
• <source>my_app_source</source>. I did this with sed, so my .travis.yml looks like this:

install:
  - docker-compose -f docker-compose_test.yml build test
before_script:
  - curl -L https://codeclimate.com/downloads/test-reporter/test-reporter-latest-linux-amd64 > ./cc-test-reporter
  - chmod +x ./cc-test-reporter
  - ./cc-test-reporter before-build
script:
  - docker-compose -f docker-compose_test.yml run --name app_test test
after_script:
  - docker cp app_test:/app/coverage.xml ./coverage_docker.xml
  - docker-compose -f docker-compose_test.yml down
  - cat coverage_docker.xml | sed "s|<source>.*</source>|<source>my_app_source</source>|" > coverage.xml
  - ./cc-test-reporter after-build --exit-code $TRAVIS_TEST_RESULT

I can confirm that this is not fixed and the only currently workaround is to use sed.
