Answer 1

Yes You can set order using the order no with the test_name, See the below example-

public class MyEspressoTest
        extends ActivityInstrumentationTestCase2 {

    private UserLoginActivity mActivity;

    public MyEspressoTest() {
        super(UserLoginActivity.class);
    }

    @Before
    public void setUp() throws Exception {
        super.setUp();
        injectInstrumentation(InstrumentationRegistry.getInstrumentation());
        mActivity = getActivity();
    }

    public void test1InvalidPropigerLogin() {
        // Type text and then press the button.

        //setContentView function to see the layout

        onView(withId(R.id.username))
                .perform(typeText("hill.hacker@gmail.com"), closeSoftKeyboard());
        onView(withId(R.id.password))
                .perform(typeText("hhhhh"), closeSoftKeyboard());

        onView(withId(R.id.user_login_button)).perform(click());
        // Check that the text was changed.
        onView(withId(R.id.login_status))
                .check(matches(withText("Invalid username or password")));

        //System.out.println("Test pass with invalid user and password");
    }

    public void test2ValidPropigerLogin() {
        // Type text and then press the button.

        onView(withId(R.id.username))
                .perform(typeText("hill.hacker@like.com"), closeSoftKeyboard());
        onView(withId(R.id.password))
                .perform(typeText("gggggg"), closeSoftKeyboard());

        onView(withId(R.id.user_login_button)).perform(click());

        //System.out.println("Test pass with valid user and password");
    }

    public void test3ForgetPasswordButton() {

        onView(withId(R.id.forgot_pwd_button)).perform(click());

        //onView(isRoot()).perform(ViewActions.pressBack());

        onView(withId(R.id.email_edittext))
                .perform(typeText("hill.hacker@propiger.in"), closeSoftKeyboard());
        onView(withId(R.id.reset_password_button)).perform(click());
        // Check that the text was changed.
        onView(withId(R.id.reset_result))
                .check(matches(withText("Email not registered with propiger")));
    }
    public void test4ForgetPasswordButton2() {

        onView(withId(R.id.forgot_pwd_button)).perform(click());

        onView(withId(R.id.email_edittext))
                .perform(typeText("Hill.Hacker@like.com"), closeSoftKeyboard());
        onView(withId(R.id.reset_password_button)).perform(click());
        // Check that the text was changed.
        onView(withId(R.id.reset_result))
                .check(matches(withText("Reset password link sent successfully")));
    }
    public void test5RegisterButton() {
        onView(withId(R.id.register_button)).perform(click());

              //onView(isRoot()).perform(ViewActions.pressBack());

        onView(withId(R.id.register_name_edittext))
                .perform(typeText("Hill Hacker"), closeSoftKeyboard());
        onView(withId(R.id.register_email_edittext))
                .perform(typeText("Hill.Hacker+888@gmail.com"), closeSoftKeyboard());
        onView(withId(R.id.register_mobileno_edittext))
                .perform(typeText("9090909090"), closeSoftKeyboard());
        onView(withId(R.id.register_password_edittext))
                .perform(typeText("password111"), closeSoftKeyboard());
        onView(withId(R.id.register_confirm_password_edittext))
                .perform(typeText("password111"), closeSoftKeyboard());
        //onView(withId(R.id.register_country_spinner)).perform(click());
        //onView(isRoot()).perform(withId(R.id.register_country_spinner, Sampling.SECONDS_15));
        onData(allOf(is(instanceOf(String.class)), is("India")))
                .perform(click());

       onView(withId(R.id.register_country_spinner)).check(matches(withText(containsString("India"))));

        onView(withId(R.id.register_button)).perform(click());

    }
