To make sure multiple views do not use the same id, centralise them in the Android project: This file can go into src/androidTest/ so that it will only be included in instrumented test builds. Here are the steps to get it done nonetheless. : As said before, this will result in an Android view with ContentDescription="myAwesomeListViewId" on debug builds, this id can be used to get hold of the views using Espresso. However, adding a ContentDescription on release builds would make screen readers go crazy; we stick to injecting on debug. One of the benefits of Espresso, however, is synchronization, which as I explained before means that Espresso itself will hold off on finding any elements until it believes the app is in an idle state. Automating the Clipboard on iOS and Android, Automating Voice Commands With Siri Using Appium, Automation Digital Labs and Desired Capabilities, Automation execution in the DevOps world using GitLab CI/CD, Automation for Windows Desktop Applications, Browserstack supports mobile native automation capability, Custom Extent Reports in Selenium – TestNG, Desired Capabilities for Android Mobile Native, Desired Capabilities for Android Mobile Web, Desired Capabilities for iOS Mobile Native, Desired Capabilities for iOS Mobile Safari, Different Driver Services in Selenium and Appium, DRIVER_EXE_PROPERTY for different browsers, Early-Stage AI for Appium Test Automation, Extract ZIP and Verify Data in Excel while Automation, Fetch DRIVER_EXE_PROPERTY for different browsers dynamically, File download with Chrome headless automation, Find Off-Screen Elements in Android using Apppium.

Select Developer Options (if not activated, then click several times on build version/number in About Device Settings). Wait for RN views to become visible in the tests.
Context is provided by the Android operating system, so for instrumentation testing the context is provided by the Instrumentation API to track the interaction between android OS and to application i.e. Otherwise, the test code is exactly the same! The sample code is as follows.
onView also has an overloaded version which can accept powerful hamcrest Matcher methods to go one step beyond and perform specific operations like: Enable StrictMode to detect hidden or accidental IO or network access. Example usage in a test: Voila, you created your first Espresso to React Native test! isRoot() has no argument.
3. Java Virtual Machine (JVM), which means it requires no device or emulator.
