Android Studio - with Junit 4.12 “!!! JUnit version 3.8 or later expected:”

Question

Tried out the suggestions on this post, but I still get the error:

!!! JUnit version 3.8 or later expected:

java.lang.RuntimeException: Stub!
    at junit.runner.BaseTestRunner.<init>(BaseTestRunner.java:5)
    at junit.textui.TestRunner.<init>(TestRunner.java:54)
    at junit.textui.TestRunner.<init>(TestRunner.java:48)
    at junit.textui.TestRunner.<init>(TestRunner.java:41)

Process finished with exit code -3

Not sure what to do from here. Tried reorganizing the order of the Junit dependency. No luck, anyone else get this issue?

Android Studio V. 1.2.1.1

Solution 1

Solved the issue. I was running the JUnit tests as a standard "JUnit test" in Android Studio. I fixed the issue by resetting the configuration as a Android Test.

Solution 2

Just to add one more situation. I was having this error after updating Android Studio to 4.1 on a project using old AGP (3.3.2) and Gradle (4.10.2). What ended up solving the issue for me was removing the android.test.runner library from gradle dependencies, that is removing the following line from the app's module build.gradle:

useLibrary 'android.test.runner'

I probably got lucky to not actually need any of the classes provided by the library for unit or instrumented tests.

Solution 3

If you have updated android studio version to 4.1 wiuth latest gradle plygin. Please comment out

// useLibrary 'android.test.runner' It will fix error for you.

Solution 4

I solve this problem by moving "testCompile 'junit:junit:4.12'" to the first order in build.gradle dependency block

Solution 5

This is apparently an Android Studio 4.1 issue. There's an open ticket for that already: https://issuetracker.google.com/issues/170328018

What really solved the issue for me was reinstalling the Android 11 (API 30) SDK, according to the bug ticket above:

"...there was an issue with API 30 mock jar that was built incorrectly. Can you open Android Studio SDK Manager and try uninstalling the R SDK or any Android SDK Platform 30 please? The Gradle build will auto install it when you try to rebuild after you delete the R SDK."

This worked for me but it took a bit to work out how to create an Android Test. Go to Edit Configurations, select Android Tests from the menu on the left, click +, and fill in the details on the right.

if you want to run your test as a standard Junit test be sure your build variant in android studio is set to Unit Tests and then create a Junit test configuration.

This was the only thing that worked for me - thank you!

Also had to remove useLibrary 'android.test.base' and useLibrary 'android.test.mock' - thanks!
