Unit testing with Flavor keeps failing and show 'The events were not received'

Question

I set,

    testOptions {
        animationsDisabled = true
        unitTests.all {
            useJUnitPlatform()
        }
    }

And I am using Java Home for Gradle JDK.

The error is here:

Execution failed for task ':app:testDevDebugUnitTest'.

The difference was just using Flavor.

testDevDebugUnitTest

My guess is adding flavor changes the path that needs while testing and this happened. So, I've changed path and also changed testImplementation to testDevImplementation but didn't work.

I added dev flavor this happened.. What have I been missing?

This is because JUnit4 is used with JUnit5. In this case, JUnit4 is not approachable. To be able to use JUnit4(backward compatibility), You need to use junit vintage like this:

dependencies {
    testRuntimeOnly 'org.junit.vintage:junit-vintage-engine:5.8.2'
    ...
}

Thank you so much! This is not the first time android studio messages are vague and cryptic - maybe one day AS will start giving proper error messages, which will actually point us in the right direction, instead of googling for 3 hours some generic error message – qkx Dec 01 '22 at 05:07
@qkx That's true, converting from groovy to kotlin can be better. – c-an Dec 01 '22 at 05:22
