React Native + Appium iOS elementByAccesibilityId.text()

问题

I'm writing tests for React Native using Appium + Jest for both Android and iOS.

Here's my React Native element:

<Text accessibilityLabel={'emailError'}>Invalid email</Text>

Here's the Promise chain I created to extract the value of a React Native Text element:

driver.elementByAccessibilityId('emailError')
      .then(error => error.text())
      .then(errorText => expect(errorText).toBe('Invalid email'))

On Android, this test passes. On iOS, this test fails, and errorText === 'emailError'.

Why is this, and is there a solution that works cross-platform for extracting text?

回答1:

I had the same issue. Using testID instead of accessibilityLabel worked for me on iOS. For Android, accessible: true and accessibilityLabel should do the trick. But: You can't just set them all. If accessibilityLabel and testID are both set, it won't work on iOS anymore.

Example for iOS:

<Text testID={'emailError'}>Invalid email</Text>

Example for Android:

<Text accessible={true} accessibilityLabel={'emailError'}>Invalid email</Text>

A library (or just create your own function) like https://github.com/tipsi/react-native-testid can help you with setting the correct attributes based on the platform.
