Run step-by-step
BugBug supports step-by-step execution of the tests. To do this, click Run and stop here between steps. This will activate the paused mode. In this mode, you can run a test step-by-step and completely control an execution process.
To enable step-by-step execution, click on the "Run and stop here" action.
Paused mode. To execute next step click on the "Run next step and pause" icon
