note

Currently, React Native API does not provide a method to mark an input text as being in an error state. https://github.com/facebook/react-native/issues/30848

Testing

Procedures

1. Turn on a Screen Reader.
2. Focus the form field.
3. Evaluate whether the label adequately and uniquely describes the component.

Error messages

1. Turn on a Screen Reader.
2. Focus the form field.
3. Trigger a validation error
4. Confirm that:
   • The error message is visible
   • The error message is announced by the Screen Reader

Outcome

Ensure all the following checks are true:

• Ensure visual labels are available for all form fields.
• Confirm that a screen reader announces all form field labels accurately.
• Check that the label, even when isolated from context, distinctly and clearly conveys the control's purpose and the required user action.
• Ensure that field constraints are appropriately announced by a screen reader.
• Verify that required fields are distinctly indicated through a screen reader.

Error messages

• The occurrence of an error is signaled:
  • The error is visibly displayed.
  • The error is announced by a screen reader.
• Error messages offer clear insights and guidance on how to rectify it.

1. The "selected state" indicates that a Screen Reader user has focused on the field but has not initiated any action yet.↩
