Unable to find any .xccoverage file (CircleCI)

[lomudi]

Hi,

I'm getting Unable to find any .xccoverage file while running the danger-xcov with CircleCI.
It's working locally, I have tried to set the derived_data_path to Build following this issue (the scheme setting is ok).

gem install danger --version '~> 4.0' && danger
Fetching: danger-4.3.5.gem (100%)

I'm working with the must update xcov version:

gem install danger-xcov
Fetching: xcov-1.2.0.gem (100%)
Successfully installed xcov-1.2.0
Fetching: danger-xcov-0.2.4.gem (100%)

Thanks in advance :)

Hi @lomudi 👋

Have you run your tests before launching Danger? xcov depends on the output of a prior tests pass.

[lomudi]

yup @nakiostudio :)
the test runs a few steps before.

[nakiostudio]

Ok! another question. Do you have gather coverage enabled as specified here?

[lomudi]

yup yup...
you can see it enabled here.

while running xcov locally it's working fine.

i guess it's something with the path to the .xccoverage file.

[nakiostudio]

Indeed, do you have a custom derived data path?

[lomudi]

not that I'm aware... you have had such an issue with CircleCI? maybe something they are playing with during the build process.

[lomudi]

from the test phase of the process, i can see this path of drive data
Signing /Users/distiller/Library/Developer/Xcode/DerivedData/ZappPlugins-dtujruptfzsvuxcrtqbcbskwqygj/Build/Products/Debug-iphonesimulator/ZappPlugins.framework

[nakiostudio]

I remember transitioning from Jenkins to CircleCI and not having to do anything to make it work.

[nakiostudio]

Oh, that's helpful! in that case you don't need to set the derived_data_path option. Try without it.

[lomudi]

Tried before. I added it after looking for a solution, saw it here fastlane-community/xcov#13 so I gave it a shot.

[nakiostudio]

I think the problem is the project configuration or how the tests are launched.

• Are you passing -enableCodeCoverage YES to xcodebuild to run your tests?
• To confirm you have a project or xcodebuild config problem, could you run the job with SSH access and then inspect the contents of ~/Library/Developer/Xcode/DerivedData/ZappPlugins-dtujruptfzsvuxcrtqbcbskwqygj/Logs/Tests/ after running the tests? There should be a .xccoverage file in that folder.

[lomudi]

thanks @nakiostudio 🙏
it was a problem with my test script, now it's working 💯

[nakiostudio]

Great! 👍
