🔀 Scenario Variables

Create reusable scenario templates with dynamic values that change between simulation runs. Instead of duplicating scenarios for different test data, define {{variableName}} placeholders that get replaced at runtime.

Key Features:

  • Inline variable editor — Type {{ in any scenario step to create or reference variables with autocomplete
  • Three-stage lifecycle — Define placeholders in scenarios, optionally pre-set defaults on run plans, and provide final values at runtime
  • Multiple instances — Add the same scenario multiple times to a run plan, each with different variable values, to create a test matrix
  • API support — Pre-set variables on run plans and pass them at runtime via the SDK, with global or per-scenario modes
  • Reserved variables — System variables like {{persona.name}} and {{phoneNumberToDial}} are automatically resolved

Use Cases:

  • Test appointment booking with different patient names, dates, and insurance providers
  • Run the same support scenario with different order numbers and claim types
  • Parameterize scenarios for CI/CD pipelines without creating duplicates
