Coding Mode (evaluating as a JS-expression)

Include calculations and JavaScript features in your scenarios 🧠

You have the option to enable or disable JavaScript evaluation in scenario steps (ECMAScript 5.1):

Please note that if you enable this option and make a syntax mistake, the scenario will pause with an exception message.

Checking expressions

You can verify the result of your expression by clicking the "Check the expression" link. You'll need to provide an object ID for validation.

Don't mix "Check the expression" feature with step testing.
