Android JNI C++ Test

How to test JNI C++ code？

What I do now:

1. write some C++ test code to call the function that I want to test
2. write some Jni to call C++ test code
3. write some Java test Code to call Jni code

but these test C++ And Java test code will remain in release apk.

Is there best pratice to test Jni C++ code ?

@oncealong What about tring androidx.test.ext.junitgtest? It can be used to run C++ gtest code with Java/Kotlin JUnit runner on real device/Emulator.
