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.r         


        

Answer 1

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

Answer 2

Running an "Android JUNit" config and having JUnit 4.12 in gradle did not help to resolve this.

I needed to select JRE to Android API 27 Platform in the run config manually instead of "Default" to resolve the issue.

Answer 3

I was also getting similar error when I added new project to workspace. May be they(new Project) would have upgraded Junit version or manadated that project should always use specific version.

In this cases, I closed project(all) along with original workspace and opened in new one.

Answer 4

The below fix is a work around and a repetitive task you need to perform on every new class that you create. I have used Gradle for my project on Android Studio.

Step 1: Go to Run-> Edit Configurations Option

Step 2: For each JUnit test configuration, change and add the below into the fields: a) JRE: Default is selected. Change it to the JRE version you have on your PC which you get as an option in the drop-down. As of today, its 1.8 b) Before launch field: Click on '+', select your module and add task as "clean compileTestJava". Move it to top in the list JUnit test configuration

Step 3: Apply Changes and now run your java class.

Answer 5

I've managed to solve it with simply editing the project's app.iml and moving order entry after from bottom:

<orderEntry type="library" exported="" scope="TEST" name="junit-4.12" level="project" />

Answer 6

Running into this when opening an old project into latest Android Studio 2.3 after it auto-updated the project.

Android Studio supports "Android JUnit" tests which should run using the current host JRE and properly support JUnit 4+. The error is due to the wrong JRE being used.

Solved by using Edit Configuration > select the Android JUnit configuration > edit the JRE. Select any choice, use Apply, then change it back to "Default (Android Platform)" for it work.
