As part of a migration from Fastlane to Golang Steps, I have ported our Ruby FTL integration to a Bitrise step.
This is my first step so I’m very open to feedback. Currently we’re using the step to run tests successfully on Firebase Test Lab. As we’re using this in production, it’s not an issue for me to spend time fixing up the code.
Also you might not be aware, FTL has an API. For advanced use cases, this is more flexible than wrapping the python CLI.
