This guide outlines how to record and run steps in the mabl Trainer.

Default steps

When you start to record steps in a new browser test, two default steps are added to the beginning of the test:

  • Set viewport size to width 1000 and height 800 (This step is ignored in mobile tests.)
  • Visit URL assigned to variable "app.url"

The record button

When the record button is turned on, the mabl Trainer records your interactions with the application under test as test steps (recorded actions). If you want to take a break from recording steps in a training session, you can turn the record button off.

The Trainer cursor

The Trainer cursor (...Waiting for input) indicates where new steps are recorded.
