Add a combined ViewMatcher and ViewAction expression to the activityLaunch() method to locate the view containing the button_main button, and include a ViewAction expression to perform a click: The onView() method lets you use ViewMatcher arguments to find views. When trying to scroll, be sure to close the keyboard first: When running tests together in a suite rather than individually, be aware that the Activity from the previous test may still be running. The animations are attractive when using the device, but they slow down performance, and may also cause unexpected results or may lead your test to fail. you need to exclude the older versions from espresso to avoid collisions: Other than these imports it is necessary to add android instrumentation test runner to build.gradle android.defaultConfig: For non flaky test it is recommended to set following settings on your devices: Quite a setup from the real world ha? super View> interface. Most important ones can be found in the following cheat sheet: All of these are very useful for everyday use, but if you have more complex views writing your custom matchers can make the tests more readable and you can reuse them in different places. Build the PhoneNumberSpinner app from a previous lesson. So I tried isCompletelyDisplayed() but as I was swiping just before the check, even with animations turned off, Espresso doesn't seem to manage that. You can use suites of automated tests to perform all of the UI interactions automatically, which makes it easier to run tests for different device configurations. Add another @Test annotation and a new textInputOutput() method to the ApplicationTest class to test text input and output: The above method uses a ViewMatcher to locate the view containing the editText_main view, and a ViewAction to enter the text "This is a test." Using instrumentation makes it possible for tests to invoke methods in the app, and modify and examine fields in the app, independently of the app's normal lifecycle. What framework or methodology would you recommend for a Data Science team? This means there is a possibility the view that you want to test may not be in the view hierarchy at that time. Word 15": The code above uses a method called childAtPosition(), which is defined as a custom Matcher: Implement a custom matcher: The custom matcher extends the abstract TypeSaveMatcher class and requires that you implement the following: You can record multiple interactions with the UI in one recording session. See. But you can't possibly cover all permutations of user interactions and all of the app's functionality. For example, type safe matcher that validates an image view has correct drawable: Usage of the matcher could be wrapped like this: Bounded matchers are similar you just dont have to do the type check but, since that is done automagically for you: https://developer.android.com/reference/android/support/test/espresso/matcher/ViewMatchers.html. Asking for help, clarification, or responding to other answers. onView(withId(R.id.gettingStarted)).check(matches(isDisplayed())); I get a .NoMatchingViewException: No views in hierarchy found matching: with id: is <2131296645> Has anyone seen anything like this before? Proper use cases for Android UserManager.isUserAGoat()? ), Internationalization and localization (I18N and L10N), Library Dagger 2: Dependency Injection in Applications, Port Mapping using Cling library in Android, ProGuard - Obfuscating and Shrinking your code, Publish .aar file to Apache Archiva with Gradle, Storing Files in Internal & External Storage. It then uses another ViewMatcher to find the view with the button_main button, and another ViewAction to click the button. Espresso easily found this login EditText view and all the tests passed. Who can use spell-scrolls done by a bard using their 'Magic Secrets' ability? How can I make the story less predictable? You can safely ignore them and fix the test itself. It must find the view you want it to find on the screen, and it must interact with it, such as clicking the view, and checking the contents of the view. Asking for help, clarification, or responding to other answers. Test to see whether an activity is launched: Using a ViewAction expression to perform a click. Also hamcrest matchers could help to have more complex conditions. Assign the array used for the spinner items to a new array to use within the iterateSpinnerItems() method: In the statement above, the test accesses the application's array (with the id labels_array) by establishing the context with the getActivity() method of the ActivityTestRule class, and getting a resources instance in the application's package using getResources(). Similarly, we can use other RecyclerViewActions as well. // anything is a hamcrest matcher that always matches. How to stop EditText from gaining focus at Activity startup in Android, Android “Only the original thread that created a view hierarchy can touch its views.”. Note that this is a workaround and will collide with other Views that have the same content description. Scale of braces of cases environment in tabular, (Piano) How should I play this harmonic unison. The goal of this test is to open the spinner, click each item, and then verify that the TextView text_phonelabel contains the item. The test demonstrates that the code retrieving the spinner selection is working properly, and the code displaying the text of the spinner item is also working properly. Also always a good place for reference is the official documentation: https://google.github.io/android-testing-support-library/docs/espresso/index.html, Advanced espresso video suggestions by Google:
