I haven't investigated the get_it implementation extensively enough, but here's an estimation of tasks involved:

1. Add/Enforce a module structure, where you can retrieve all the bean definitions, for ex. Module.getDefinitions()
2. Provide mocked/fake beans for the definitions
3. Try getting the beans. If a definition isn't provided fail the test

There's also an area I'm not sure how to avoid. The last layer, for ex. ViewModel might not be defined in the configuration, so the test will result in a false-positive. Potential solution: go through all files instead of Module.getDefinitions() and mimic getIt<XY>()
