Unable to run android instrumentation testcase ( Kotlin ) in android studio

I have written simple instrumentation test in kotlin as below

@RunWith(AndroidJUnit4::class)
class SampleTestCase {

    fun testCaseCheckPackageName() {
        val appContext = InstrumentationRegistry.getTargetContext()
        assertEquals("com.niks.sample1", appContext.packageName)
    }        
}

Everything works fine when i am creating androidTest apk & even testcase are running fine but throwing below stacktrace in android studio.
