Kotlin functions providing ActivityTestRule and IntentsTestRule with a simplified syntax.

AndroidTestRules.kt

import android.app.Activity
import android.support.test.espresso.intent.rule.IntentsTestRule
import android.support.test.rule.ActivityTestRule

inline fun <reified T : Activity> activityTestRule(initialTouchMode: Boolean = false, launchActivity: Boolean = true) =
        ActivityTestRule(T::class.java, initialTouchMode, launchActivity)

inline fun <reified T : Activity> intentsTestRule(initialTouchMode: Boolean = false, launchActivity: Boolean = true) =
        IntentsTestRule(T::class.java, initialTouchMode, launchActivity)

Example usage:

@RunWith(AndroidJUnit4::class)
class MyTestClass {

	@Rule
	@JvmField
	val activityRule = activityTestRule<MainActivity>()

	@Rule
	@JvmField
	val intentsRule = intentsTestRule<MainActivity>(launchActivity = false)
}
