request: whilePerforming for individual tests

[xVemu]

Is there an existing feature request for this?

• [X] I have searched the existing issues.

Command

Ability to perform actions for every test individually

Description

GoldenTestScenario should have whilePerforming parameter, so every test could have different action. Currently, to create the same scenario but different actions, you have to create a second file.

Reasoning

I want all test to be in single file, because they all corresponds to the same widget.
