Android: Unresolved reference when using junit 4.13

Question

After updating junit version to 4.13 in gradle dependencies, classes and annotations like Assert, @Test, etc. under the junit package are displayed as red when used in my code. Lint check says:

Unresolved reference: <any junit class>

However, when I build and run my tests, it will build and run just fine.

I have tried:

• restarting Android Studio
• Invalidate caches and restart
• Clean and rebuild project
• added testImplementation "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version"

What works is downgrading junit to 4.12. How to get rid of this lint error, without downgrading version?

Update:

• When I check ALT + ENTER options and select Inspection 'Unresolved reference, in wrong test scope' options > Suppress 'IncorrectScope' for file <name of file>, it gets rid of these lint errors for that particular file. I still like to solve this problem without using Suppress though.
• According to this issue, it looks like this bug is not fixed yet. For now I'm downgrading to 4.12.
• Removing both espresso and runner from dependencies also fixes the problem.

Answer 1

Just add the following to your build.gradle (App) file:

configurations.all {
    resolutionStrategy.force "junit:junit:$junit_version"
}

dependencies {
...
}
