Changes

Forgot Password Form

Submitting an empty form marked the field with red but did not display the error message.

Now the error message is displayed correctly.

Additionally it was allowed to submit the form with an invalid email address. This is no longer allowed.

Login Form

Submitting an empty form marked the fields with red but did not display the error messages.

Now the error messages are displayed correctly.

Signup Form

Submitting an empty form marked the fields with red but did not display the error messages, except for the last field.

Now the error messages are displayed correctly.

Note that the password field has its own way to display the error message (only when it has focus).

Testing

Please describe how this can be tested by reviewers. Be specific about anything not tested and reasons why. If this library has unit and/or integration testing, tests should be added for new functionality and existing tests should complete without errors.

• This change adds unit test coverage
• This change has been tested on the latest version of the platform/language or why not

Checklist

LGTM

Note that the password field has its own way to display the error message (only when it has focus).

Definitely something we should raise to our designer to strive for that consistency.
