Android espresso 测试在本地通过，但在 Firebase 测试实验室失败

Question

I have issue with android espresso test. Test pass locally but fail on FTL. It's simple test

onView(allOf(withId(R.id.text_supercategory_name), withText("Air conditioners"))). check(matches(withText("Air conditioners")));

this test pass locally. On FTL I have error:

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: (with id: blablabla:id/text_product_verdict and with text: is "Air conditioners")

I'm not understand whay I see ID which not used in my test id/text_product_verdict … and this ID from another activity … Activity for test is correct

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

I checked the video of the failed test on FTL and see a lot of notifications on emulator img from FTL

I decide that the problem was a sticky notification from Google Hangouts and try run my test with --no-auto-google-login flag. But have the same results. With onView(withText("Air conditioners")).check(matches(isDisplayed())); test pass on FTL.

Is anyone can help with with issue?

Answer 1

It happened to me as well. It seems Firebase Test Lab does not recognize the id at withId(R.id.text_supercategory_name) in some devices. We can use res-name instead.

Check out the view hierarchy in the log and grab the res-name in there with onView(withResourceName("res-name")).perform(click());

// change res-name to buttonPanel, button3, button2, or button1

Answer 2

I found this issue also when using espresso. Then I using Barista for espresso wrapper. It's helping me to choose using R.id.name or R.string.name or "name" as the selector. Here click example from their GitHub :

clickOn(R.id.button);
clickOn(R.string.button_text);
clickOn("Next");

The ID(integer value) of the view is dynamically changed in each build. It works when when the same build of the app and test apk are upload to firebase. However when different builds are uploaded, it fails.
