Edit and Play JavaScript Steps for Web Testing

Last reviewed: September 24, 2026

Use Edit and Play when a web testing step needs targeted JavaScript adjustment and immediate playback validation.

What changed in this article

• Use small, reviewable JavaScript changes rather than replacing large scenario sections with custom code.
• Replay the edited step in the same browser profile and test node that will run the scenario.
• Keep Scenario Editor terminology in the article and avoid older Designer-only phrasing.

Validation workflow

1. Open the affected web test step and make the smallest JavaScript change needed.
2. Use Play to validate the step immediately against the application state.
3. Save the scenario and run a short playback to confirm the edited step works in context.

Review note: Modernized the title, changed wording to Scenario Editor/Web Testing, and emphasized step-level validation after JavaScript edits.
