Answer 1

Android Manifest

        <activity
            android:name=".SplashActivity">

            <!-- move this code to the activity you want to launch first -->
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <!-- move this code to the activity you want to launch first -->

        </activity>

        <activity
            android:name=".MainActivity">

        </activity>

Answer 2

Using ActivityTestRule you can specify the activity that you would like to test.

Adding the following code in your test class:

@get:Rule
var activityRule: ActivityTestRule<MainActivity>
       = ActivityTestRule(MainActivity::class.java)

Should specify the activity that you would like to use for testing. See Use Espresso with ActivityTestRule for more details.
