AI Assertions

Overview

AI Assertion is an option available within the Add Assertion action.

It allows you to validate test conditions using natural language instead of classic assertions based on locators or fixed values.

Instead of asserting a single element, the AI evaluates the context provided by the selected Assertion Scope and determines whether the condition is met.

Assertion Scope Options

The Assertion Scope defines what information the AI can analyze. Only one scope can be selected per AI Assertion.

Web Tests

1. Web Page

When Web Page is selected, the AI processes:

  • The current URL
  • The full page source (HTML)
  • A screenshot of the page

Example prompts:

  • Confirm that the page is in French
  • Verify that the visible page content is free of grammar mistakes
  • Check that the background includes a sports car

2. Cookies

Allows the AI to read and reason about browser cookies.

Example prompts:

  • Check that the cookies indicate an authenticated user session
  • Verify the presence of a third-party tracking cookie from HubSpot

3. Variables

Allows the AI to inspect previously defined test variables.

Example prompts:

  • Check that the $products variable is an array with at least 50 items
  • Verify that the total cost correctly includes VAT based on the listed product prices

4. Test Execution Logs

Allows the AI to analyze the execution logs generated so far.

Example prompts:

  • Verify that there are no warnings so far
  • Check that the test execution accessed at least 5 Wikipedia pages related to cars
  • Verify that there was no Wait Until step that waited for more than 30 seconds

Mobile Tests

For Mobile Tests, web-specific scopes are replaced with App Screen.

1. App Screen

When App Screen is selected, the AI processes:

  • The app screen source
  • A screenshot of the current screen

Example prompts:

  • Verify that the screen shows only pictures of dogs
  • Confirm that this section is showing only books related to chemistry
  • Verify that the map has loaded

Assertion Strictness Levels

Each AI Assertion allows you to control how strictly the condition is evaluated.

  1. Strict The condition must be clearly and unambiguously true. Best for critical validations.

  2. Standard Balanced interpretation with minor flexibility. Recommended for most tests.

  3. Lenient Allows partial matches and ambiguity. Useful for unstable environments or early testing stages.
