February 2023 Release Notes

New | Enhancements | Changes | Bug fixes


Early access for authenticator MFA support

We recently added support for MFA logins that use time-based one-time password (TOTP) authentication! Currently available as an early access program, our MFA support allows you to increase testing coverage to include applications that require a temporary code from an authenticator app in addition to username and password.


MFA support was the winner of the 2023 mabl Hackathon.

Run specific DataTable scenarios ad hoc

We now support running a specific DataTable scenario for ad hoc test runs! You can run a specific DataTable locally or in the cloud to get quick feedback on your test. Learn more.

Right click support

The mabl Trainer now supports recording right click steps, which you can use to test application functionality that is only accessible from a custom context menu. Learn more.

Save the results of a CSS / XPath custom find to a variable

You can now create a custom find step that uses CSS or XPath to target a specific element and store a property of the target element, such as the innerText, in a variable. Learn more.
