Exception when running instrumented tests with Hilt and App Startup

[ampeixoto]

Hello,

I am starting to setup some instrumented tests on my project, but when I run them, I get the following exception on logcat:

My real codebase is much more complex, but I created a much simpler project where I am able to reproduce the issue HERE.

From what I understood, when running the instrumentation tests, the startup code is first executed, even before anything on the test class (before @before and @BeforeClass methods).

What is the best way to handle this? Is this something that was already detected?
