AI validation

Describe what should appear on screen in natural language, and AI will verify it in your App Low Code Automation tests.

AI validation lets you describe the expected screen state in plain English and have AI verify it. Unlike page, text, and element validations, which compare a single target against a single expected value, AI validation can assess the screen as a whole.

Use AI validation for checks that standard validations can’t perform, such as:

• The product image has loaded and is not a gray placeholder.
• The subtotal plus tax equals the total.
• The bottom navigation bar contains five items, and only one is active.
• The primary button uses a solid style, and the screen is in dark mode.
• No error banner overlaps the search results.

AI validates your prompt against both the screenshot and the page source of the current screen, and returns a pass or fail result with an explanation. To validate against only the screenshot or only the page source, state this explicitly in your prompt. To verify that an element is absent, state this explicitly in your prompt.

Add an AI validation

To add an AI validation step, follow these steps:

The following video shows how AI runs the validation and returns the result:

Examples:

• Validate if "the product image is loaded and is not a gray placeholder"
• Validate if "the subtotal plus tax equals the total shown above them"
• Validate if "there are exactly five items in the bottom navigation and only one is active"
• Validate if "the screen is in dark theme"
• Validate if "no error banner is covering the results"
• Validate if "the Proceed to Checkout button is a solid filled button with white text"
• Validate if "the check-in date shown in the search form is earlier than the check-out date"
• Validate if "@unit_price * 2 is equal to @cart_total"

Write a good prompt

AI checks the prompt as you wrote it. A clear prompt gives a stable step. Follow these tips:

• Be specific. Name the element or area and state the exact condition. For example, instead of the cart looks right, write the Order Summary card shows 2 items and a total of $49.98.
• Include every condition. You can combine multiple checks in one prompt.
  • To pass all the checks, join them with and.
  • To pass at least one check, join them with or.
• Specify the source, if needed. AI checks the screenshot, the page source, or both. If the two sources disagree, AI uses one of them. To use a specific source, add use the screenshot or use the page source to the prompt.
• Use variables for data checks. If a prompt compares only variables, AI doesn’t need the screen. To insert a variable, type @.
• Write prompts that work on both platforms. The same prompt runs on Android and iOS. Because screens differ across platforms, a prompt that passes on one platform might fail on the other. To use a different prompt for each platform, place one prompt in an If device.os is Android block and the other in the Else block.

Rules and constraints

• Every run uses AI. This includes authoring, replays, and cloud runs. In a loop, each iteration uses AI. In a module, each module run uses AI.
• You can add the step inside if-else blocks, loops, and modules. You can’t use it as an If or Repeat condition.
• The screenshot and page source use the device language. If the device language isn’t English, an English prompt might fail.
• AI validation checks the screen against your prompt, not against a saved baseline. It isn’t a pixel-level visual check.
