Overview

The AI_ASSERTION step uses AI to verify complex assertions about the page content. It takes a screenshot and analyzes both the visual appearance and HTML content to determine if your assertion is true.

​
Parameters

​
assertion
string
required
Natural language assertion to verify. The AI will analyze the page to determine if this assertion is true.

​
Behavior

  1. Screenshot Capture: Takes a screenshot of the current page
  2. HTML Collection: Gathers the page HTML structure
  3. AI Analysis: Sends screenshot and HTML to AI service
  4. Assertion Evaluation: AI evaluates if the assertion is true
  5. Result Return: Returns success if true, failure with explanation if false

​
Common Use Cases

  • Verifying complex visual layouts
  • Checking content organization and structure
  • Validating UI consistency and branding
  • Verifying responsive design behaviors
  • Checking for the presence of specific UI patterns
  • Validating data visualization correctness

​
Error Handling

The step will fail if:
  • The assertion evaluates to false
  • The AI service is unavailable
  • The screenshot cannot be captured
  • The page content cannot be analyzed
When assertions fail, the AI provides detailed explanations of why the assertion was not satisfied, helping with debugging.
