SoLoader causes instrumented tests to crash

See original GitHub issue

Bug Report

SoLoader looks for libfbjni in the .test path during instrumented tests. I am not sure how it makes that decision, since package name still reports without .test. Since the tests use a debug variant, I don’t see a way to prevent Flipper loading during instrumented tests.

Yes, I can see a commit that explains why this happens as well as the applied fix: https://github.com/facebook/SoLoader/commit/90084463c550b537501524f00153575d010b2f21

Hi,

I encountered the same issue while running Detox (instrumented tests) on a React Native 0.68 project with Hermes enabled. AndroidJUnitRunner would instantly crash at startup.

...
crashes with java.lang.UnsatisfiedLinkError: couldn't find DSO to load: libhermes.so

I was able to solve it by downgrading SoLoader to v0.9.0+ using resolutionStrategy.

Any idea why this is happening?

EDIT: I also tried various 0.10.x versions v0.10.1 is working v0.10.2 is crashing v0.10.3 is crashing

Looks like something broke in v0.10.2
