How do I set

android {
    testOptions {
        unitTests {
            includeAndroidResources = true
        }
    }
}

Using kotlin gradle DSL? I could only get it to run using the groovy one

you can do either of these

android {                            
    testOptions.unitTests.isReturnDefaultValues = true

    testOptions {
        unitTests.isReturnDefaultValues = true
    }
}

Ah, the

isReturnDefaultValues

, gotcha

actually, bad copy/paste on my part,

testOptions.unitTests.isIncludeAndroidResources = true
        testOptions {
            unitTests.isIncludeAndroidResources = true
        }
