......
@RunWith(AndroidJUnit4::class)
class HogetAccountTest {

@Test
    fun LoginLogoutTest() {
        // test code in here
    }
}

To run LoginLogoutTest() method

$ ./gradlew connectedAndroidTest -P android.testInstrumentationRunnerArguments.class=com.hoget.instrumenttest.testcases.accountTest.HogetAccountTest#LoginLogoutTest;

or

$ ./gradlew connectedAndroidTest -P android.testInstrumentationRunnerArguments.class=com.hoget.instrumenttest.testcases.accountTest.HogetAccountTest.LoginLogoutTest;
