Unable to find method ''void com.android.build.api.extension.AndroidComponentsExtension$DefaultImpls.androidTest$default(com.android.build
In my case the problem was incompatibility between Android Gradle Plugin and Hilt library. After upgrading Hilt to the latest version, I can also use the latest AGP.
[EDIT]
It seems that recent release of Android Gradle Plugin has fixed the issue and
AGP version 7.0.0-beta05 works with Hilt version 2.37.

In my case AGP 7.0.0 builded successfully with Hilt 2.37
