SimpleCov Reporting Differences Between v0.17.1 and v0.18.0

[vanessadean]

Wanted to surface this issue that has already been reported to Code Climate: codeclimate/codeclimate#937

We ran into same error using simplecov in conjunction with Code Climate after upgrading from 0.17.1 to 0.18.0:

Error: json: cannot unmarshal object into Go struct field input.coverage of type []formatters.NullInt
Usage:
  cc-test-reporter after-build

Here is the version of Code Climate we are running:

RUN curl -L https://codeclimate.com/downloads/test-reporter/test-reporter-0.7.0-netcgo-linux-amd64 -o /usr/local/bin/cc-test-reporter && \
    chmod +x /usr/local/bin/cc-test-reporter

Thanks!

Hi @vanessadean ,

thanks for the report 💚

This is a known issue and you can find more background on it here: codeclimate/test-reporter#413

The short version from my side:

• code climate integrates with us through an implementation detail whose format was never meant for integration or was documented or anything like that
• we mentioned this over 2 years ago
• Before releasing this we gave them notice where communication at one point fizzled out a bit Possible Incompatibility with SimpleCov 0.18+ codeclimate/test-reporter#413 (also pointing out other problems with this)
• Now it's broken
• I'll still try to work with them to find a solution that is doable. I'm admittedly not ecstatic about having to change stuff in SimpleCov so that a third party service can work but of course I want people to be able to use SimpleCov and CodeClimate.

So we'll see where/how this goes.

I'll close this issue though, imo the main issue for this is: codeclimate/test-reporter#413
