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
}
}
