Active build variant does not have a test artifact

Question

I have created a new build type called 'bitrise' based on the 'debug' build variant. The instrumented androidTests build and run fine when using the 'debug' build variant however when I switch over to my new 'bitrise' build variant I get the following errors:

Process finished with exit code 1
Class not found: "com.mycompany.app.ui.race.RaceFragmentUiTest"

And this warning when I select "Edit Configurations..." -> "Android Instrumented Tests"

Versions

'com.android.tools.build:gradle:3.5.2'

Android Studio 3.5.2

This is an extract from my Gradle file:

buildTypes {
    debug {
        debuggable true
        testCoverageEnabled = false
        applicationIdSuffix ".debug"
        buildConfigField("String", "BASE_ENDPOINT", BASE_ENDPOINT_DEBUG)
    }
    release {
        minifyEnabled true
        zipAlignEnabled true
        shrinkResources true
        buildConfigField("String", "BASE_ENDPOINT", BASE_ENDPOINT_PROD)
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    bitrise {
        initWith debug
        buildConfigField("String", "BASE_ENDPOINT", BASE_ENDPOINT_PROD)
    }
}

flavorDimensions "version"

productFlavors {
    mycompany {
        dimension "version"
        applicationId "com.mycompany.app"
    }
    second {
        dimension "version"
        applicationId "com.second.app"
    }

My unit tests run fine in all configurations, I only have an issue with Android Instrumented Tests

I have tried these steps: https://developer.android.com/studio/build/build-variants#sourcesets, TestCase class not found by Android Studio, Android Studio Unit Testing: unable to find instrumentation OR class not found ex

Answer 1

You can add this to your build.gradle file

android {
    testBuildType "MycompanyBitrise" // or whatever build varient where you are getting 
                                       such error
}

Answer 2

Or Just switch to debuggable flavour/buildType. Solved issue for me :)
