Log during Android Unit Test in Intellij gives java.lang.RuntimeException: Stub
I am currently trying to migrate from Android Studio to Intellij.
The problem arises when I try to run my code through unit tests. A method in the code under test calls Log.e and an exception is thrown in Intellij IDE. The same code runs fine in Android Studio. Probably my project settings may configured incorrectly in Intellij. Any one knows where to look for the problem?
java.lang.RuntimeException: Stub!
at android.util.Log.e(Log.java:31)
My Intellij command when running the unit test.

1- Add this to your build.gradle
testImplementation "org.mockito:mockito-core:${mockitoVersion}"
testImplementation "org.powermock:powermock-api-mockito:${powerMockVersion}"
Checkout the supported versions of Mockito and PowerMock
For example if you use v1.9.5 for Mockito use v1.6.6 for PowerMock
2- Annotate your test class with this
@RunWith(PowerMockRunner.class)
@PrepareForTesting(Log.class)
public class YourTestClass {
And your test cases should run now.
Also as @Code-Apprentice said if you want to log something inside the testing class use System.out.println(). Do not use Android dependencies for testing, this just to bypass the logs inside the methods you are unit testing.
UPDATE
Adding this to your build.gradle will also help with no need for PowerMock (not highly recommend). Please refer to this answer
android {
//...
testOptions {
unitTests.returnDefaultValues = true
}
}

When running unit tests, no methods from the Android API are available. The error "java.lang.RuntimeException: Stub!" occurs when you try to call any of these functions, including Log.e(). If you need output, use the standard System.out.println() instead. Or use the IntelliJ debugger.
