How to add resource-id to android in react-native

Question

I was trying to use firebase TestLab but it seems that it can only target resource-id. I had my elements like this:

<Input {...props} testID="usernameIput" />

But it seems that the testID is not mapped to the resource-id. If this is not the way to do it, then how can I get access to resource-id within react-native? If I can't what is the work around to add resource-id in android studio?

Answer 1

Came to this nearly 4 years late but as of React Native 0.64 the testId attribute is now mapped to resource-id in Android builds which means Android testing frameworks that rely on this attribute will operate correctly.

The former workaround that used the accessibleLabel shouldn't be used going forward as it actually mangled accessibility. A further rationale for this change can be found here.

Answer 2

Use both accessible and accessibleLabel on your views (so far, seems to work on View, Text, TextInput) and UiAutomator will generate content-desc field from accessibleLabel.

For now, we can use content-desc to identify tags.

DOC on accessiblity label: https://facebook.github.io/react-native/docs/accessibility.html#accessibilitylabel-ios-android.

<Text
    testID="btnText"   //works for iOS
    accessibilityLabel="btnText"    //works for android & iOS content-description
    accessible
  >
    {text}
  </Text>
