I fill up user name and password and press a button that sends the information over the network (Espresso Idling resource is implemented), in the application the next screen appears and I can see in logs that the information has being sent. But the test fails with error that it was not able to press the button: android.support.test.espresso.PerformException: Error performing 'single click' on view 'with id:

回答1:
Usually this kind of error appears when you are working on a screen whose fields are hidden behind the soft keyboard. Thus, you should do a couple of things:
- Make the layout scrollable and using ViewActions.scrollTo perform the scroll to that field.
- Close que soft keyboard using ViewActions.closeSoftKeyboard
An example:
String OLD_PWD_INPUT = "Asdf1234;";
onView(withId(R.id.old_password)).perform(typeText(OLD_PWD_INPUT));
onView(withId(R.id.verify_new_password)).perform(closeSoftKeyboard());
onView(withId(R.id.change_password_button)).check(matches(not(isEnabled())));
String NEW_PWD_INPUT = "Asdf1235;";
onView(withId(R.id.new_password)).perform(scrollTo());
onView(withId(R.id.new_password)).perform(typeText(NEW_PWD_INPUT));
onView(withId(R.id.verify_new_password)).perform(closeSoftKeyboard());
onView(withId(R.id.change_password_button)).check(matches(isEnabled()));
