As the title says, it fails some times, some others it success.
android.support.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'is displayed on the screen to the user' doesn't match the selected view.
Expected: is displayed on the screen to the user
Got: "AppCompatTextView{id=2131492981, res-name=snackbar_text, visibility=VISIBLE, width=444, height=71, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=18.0, y=0.0, text=Network Error, input-type=0, ime-target=false, has-links=false}"
The first line of stack trace suggest espresso is unable to see the Snackbar on screen. But the second line states it is in fact seeing a Snackbar with visibility=VISIBLE
and text=Network Error
which is correct.
I'm confused, what's going on?
This is my test code:
activityRule.launchActivity(new Intent());
onView(withText("Network Error")).check(matches(isDisplayed()));
PS: it mostly fails when I run the whole test suit; but sometimes it also fails when I just run this test alone. Some other times it passes green, but there isn't any pattern, seems random.
Late! But I hope that it is helpful for others:
Testing Snackbar show with Espresso
private void checkSnackBarDisplayedByMessage(@StringRes int message) {
onView(withText(message))
.check(matches(withEffectiveVisibility(
ViewMatchers.Visibility.VISIBLE
)));
}
I was getting similar issue. I was able to solve it by:
Disabeling animations as described here.
I was displaying the SnackBar after I fetched data from server so I also had to wait until the data was fetched. I managed to solve it with IdlingResource as described in this anwser.
Then I was able to successfully check the SnackBar.
I hope my points will help.
