AndroidJUnit4.class is deprecated: How to use androidx.test.ext.junit.runners.AndroidJUnit4?

For my instrumentation tests I was using



@RunWith(AndroidJUnit4.class)


from



import androidx.test.runner.AndroidJUnit4;


in order to establish my test cases. Now this line gets marked as deprecated with the hint to use AndroidJUnit4 from



import androidx.test.ext.junit.runners.AndroidJUnit4


However if I try to import AndroidJUnit4 from the named package I get the error, that ext can not be resolved.



Do you have an idea, what package should be included in gradle to resolve this issue?

    I think your source is obsolet, they do not mention androidx at all.

According to the documentation for AndroidJUnit4, the gradle file should contain the following line:



androidTestImplementation 'androidx.test.ext:junit:1.1.0'


After adding this, everything worked for me.



If it still doesn't work, make sure that you clean and/or rebuild your project.

  • @zuko Clean and/or rebuild your project, it should be there. If still not and you're using modules, check that your dependency hierarchy is setup as you expect; you might need to add these to the top level modules too—since testing libraries aren't compiled into shared modules for use by upstream modules.

  • @JonAdams my dependency tree kept holding onto a reference to older libraries for some reason even though i thought i removed them. so after trying various things i ended up just migrating the project to a new one and everything is fine now.
