As said by Ali Dehghani, You can order the test method execution by

@FixMethodOrder(MethodSorters.NAME_ASCENDING): Sorts the test methods by method name, in lexicographic order.

Code:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class ApplicationTest extends ActivityInstrumentationTestCase2 {

    public ApplicationTest() {
        super(MainActivity.class);
    }

    @Rule
    public ActivityTestRule mActivityTestRule = new ActivityTestRule<>(MainActivity.class);

    @Test
    void t1AttachUI(){
        // testing code goes here
    }

    @Test
    void t2InitializeViews(){
        // testing code goes here
    };

    @Test
    void t3SettingValues(){
        // testing code goes here
    };

    @Test
    void t4Validation(){
        // testing code goes here
    };

    @Test
    void t3AfterButtonPress(){
        // testing code goes here
    };
}
