Reporting API early access

With mabl's new reporting API, testers can integrate the results and artifacts from mabl test runs into their reporting workflow, making it easier to share mabl test run data with the larger team! The reporting API is currently available as an early access program and includes initial endpoints for reporting test run results and exporting test run artifacts.

Improvements to managing variables in the mabl Trainer

We updated the Variables modal in the mabl Trainer. The new Variables modal shows:

  1. The initial value of a variable
  2. The variable source, such as environment or DataTable
  3. The current value of the variable

The new Variables modal

You may override the variable value with a current value, which can be useful if you want to see how the test execution changes with a different variable value. Learn more.
