Unable to run parameterized tests with Android Test Orchestrator

I'm trying to run parameterized tests using Android Test Orchestrator. But for some reason parameterized tests won't start. I can run all tests properly without Orchestrator but I need it to clear some data between tests.

This is output from Gradle. It can see all 14 tests but only 12 are executed (missing 2 are parameterized):

Starting 14 tests on Nexus_5X_API_27(AVD) - 8.1.0

Tests on Nexus_5X_API_27(AVD) - 8.1.0 failed: Test run failed to complete. Expected 14 tests, received 12

Test run failed to complete. Expected 14 tests, received 12

**Gradle:**

android {

defaultConfig {
testInstrumentationRunner "foo.bar.CustomRunner"
}

testOptions {
unitTests.returnDefaultValues = true
execution 'ANDROID_TEST_ORCHESTRATOR'
}
}

dependencies {
androidTestImplementation "com.android.support.test:runner:$runnerVersion"
androidTestUtil "com.android.support.test:orchestrator:$runnerVersion"
}

**Test:**

@LargeTest
@RunWith(Parameterized::class)
class ParamTest(val param1: String, val param2: String) {

companion object {
@JvmStatic
@Parameterized.Parameters
fun data(): Collection<Array<Any>> {
return listOf(
arrayOf("param1", "param2"),
arrayOf("param21", "param22")
)
}
}

@Test
fun shouldDoSthWithParams() {
//some test
}

}

**EDIT:**

As a workaround sealed class can be used:

@LargeTest
@RunWith(AndroidJUnit4::class)
class ParamTest1 : ParamTest("param1", "param2")

@LargeTest
@RunWith(AndroidJUnit4::class)
class ParamTest2 : ParamTest("param21", "param22")

sealed class ParamTest(val param1: String, val param2: String) {

@Test
fun shouldDoSthWithParams() {
//some test
}

}

Parameterized tests aren't currently supported in Orchestrator:

The issue was fixed in version `1.3.0-beta02` of the `androidx.test:runner` library. See the [AndroidX Test 1.3.0 Beta02][1] release notes which calls this issue out explicitly as fixed.
