How to test criterion 9.10 “In each form, is the error management accompanied, if necessary, by suggestions of expected data types, formats or values?”

Test 1 (9.10)

iOS and Android

1. Activate the screen reader.
2. Fill in form input fields with values that are likely to cause input errors (e.g. entering an incorrectly formed e-mail address).
3. Validate the form.
4. For each field in error that has a format check, check that the error message includes a real example of an input (for example, for an e-mail address, check that the pattern refers to a real address, like "[email protected]").
5. If this is the case, the criterion is validated.
