How To copy unittest result out of the container without --output argument

[bqstony]

I would like to copy out the unit test results from my docker stage. Normaly i would use for this docker build --target export-test-results --output type=local,dest=testresults . But the --output parameter in the module.json doesent work.

Do you have any other idea to acomplise this?

@bqstony thanks for your question, it was added to our backlog.

@bqstony - based on https://docs.docker.com/engine/reference/commandline/build/#custom-build-outputs , if your tests are producing the outputs, docker should copy them out to local filesystem without issues. Why do you need to update the module.json?
