Hi, currently Flank doesn’t support test APKs with zero tests on Android so currently we are detecting the test count in the bytecode before including the test APK with Flank. Would it be ok if I open a PR to implement this inside Flank? This would be easier since you are using DexParser already.

When you have a project with several modules and flank is configured automatically on each Android module. If you have several modules, not configuring Flank automatically for each module is dangerous since you usually want to run all your tests with your CI.

Imagine this scenario:

Module A has zero tests currently and Flank is not applied since there aren’t tests to run. A dev adds a test on module A. He should remember to add Flank manually if that is the first instrumented test of the module A. 99% of the time he will forget to do it and the tests won’t run on the CI for that given module
