Espresso NoMatchingViewException when using withId matcher
android, android-espresso
Solution
Yes, this is how it works in Espresso. The problem here is, that in Android, the View representing the menu item doesn't have the ID of the menu item. So `onView(withId(X))` just fails to find a View. I don't have a better recommendation than just using `withText()`. If you have multiple views with the same text, using hierarchy for distinction works.
Problem
I'm trying to write a simple test where I simply click on a MenuItem that is in the main activity: ``` public class doTest extends ActivityInstrumentationTestCase2<doActivity> { public doTest() { super(doActivity.class); } @Override public void setUp() throws Exception { super.setUp(); startActivity(); } private void startActivity() { Intent intent = new Intent(); setActivityIntent(intent); getActivity(); } public void testOne() { Espresso.openContextualActionModeOverflowMenu(); onView(withId(R.id.create_new)).perform(ViewActions.click()); } } ``` The test fails with "NoMatchingViewException". If I change the onView line to: ``` onView(withText("Add new")).perform(ViewActions.click()); ``` Here is the menu xml for the activity: ``` <item android:id="@+id/create_new" android:title="Add new" tools:ignore="HardcodedText"> </item> ``` The test works. Why would the matcher withText find the view whereas the matcher withId not find?
