​
Instruction

AI-powered action step. Describe what to do in natural language, and Revyl figures out which elements to interact with.
  • Field: instruction (e.g., “Tap the login button”, “Type ‘hello’ in the search field”)
  • Supports {{variables}} in the instruction text.

​
Validation

Assert a condition on the current screen state. Fails the test if the assertion doesn’t hold.
  • Field: instruction (e.g., “The home screen is visible”, “The price shows $9.99”)

​
Extraction

Capture data from the screen into a variable for use in later steps.
  • Fields: instruction (e.g., “Get the order confirmation number”), variable_name (where to store the result)

​
Script

Run custom code in a sandboxed environment. Supports Python, JavaScript, TypeScript, and Bash.
  • Fields: code or select a library script, language, optional variable_name for output

​
Manual

Precise device-level actions that don’t require AI interpretation. Every Manual sub-type except Wait is mobile-only.

​
Loop (While)

Repeat a block of steps while a condition is true (checked each iteration).
  • Fields: condition (natural language condition), body (nested steps)
  • Default max iterations: 5

​
Decision (If/Else)

Branch execution based on a screen condition.
  • Fields: condition (natural language condition), then (steps if true), else (steps if false)

​
Module

Insert a reusable group of steps from the Library into your test. The module’s steps execute inline during the run, as if they were part of the test.
  • Field: module_id (select a module by name from the dropdown)
  • Changes to the module apply automatically to every test that imports it.
