Setup code coverage on travis with a mono-repo architecture

[flegall]

Hi,

I'm trying to set up code coverage on my travis build of js-given (https://github.com/jsGiven/jsGiven).

In my build the coverage file is located in ./js-given/coverage/lcov.info

The coverage is there, because coveralls already use it

I've setup the after_script part to :

after_script:
  - ./cc-test-reporter -p js-given after-build --exit-code $TRAVIS_TEST_RESULT

I'm having this error :

$ ./cc-test-reporter -p js-given after-build --exit-code $TRAVIS_TEST_RESULT

Error: could not find any viable formatter. available formatters: clover, cobertura, coverage.py, excoveralls, gcov, gocov, jacoco, lcov, simplecov

Usage:

  cc-test-reporter after-build [flags]

Flags:

  -s, --batch-size int               batch size for source files (default 500)

  -e, --coverage-endpoint string     endpoint to upload coverage information to (default "https://api.codeclimate.com/v1/test_reports")

  -t, --coverage-input-type string   type of input source to use [clover, cobertura, coverage.py, excoveralls, gcov, gocov, jacoco, lcov, simplecov]

      --exit-code int                exit code of the test run

  -r, --id string                    reporter identifier (default "7372bdd9c70ad42f845941f1c5fba601dc0af2bb4ec221d55f6b04d228261b2c")

  -p, --prefix string                the root directory where the coverage analysis was performed (default "/home/travis/build/jsGiven/jsGiven")

Global Flags:

  -d, --debug   run in debug mode

Regards,

Florent

Hi @flegall,

Apologies for the delayed reply, I was away for the holidays & am still catching up on some things.

Each formatter looks in a hard-coded path for the coverage information, and the lcov formatter expects to find the coverage at coverage/lcov.info. In your case it seems like the simplest thing to do might be to just cd js-given before running cc-test-reporter after-build. If you do that you'll probably also need to drop the -p js-given flag: I suspect the actual file paths listed in your lcov.info are already relative to js-given, e.g. that file would have an entry for src/Stage.js, not js-given/src/Stage.js.

Let me know if that helps.

In case this helps someone in the future. I'd simply forgotten to generate my report file. Be sure to check that this file is actually generated.
