Pixel Validation and Pixel Wait-for use a comparison tool that reports visual differences up to the pixel level or your app's Elements, Viewport and even entire Document. This functionality is provided as a service by Applitoos and requires integration.
How to add Pixel Validation
- Hover the arrow menu where you want to add your validation step.
- To add validation click ‘+’ ⇒ ‘Validations’
- Depending on the wanted scope of pixel comparison select either ‘Validate element pixels’, ‘Validate viewport pixels’ or ‘Validate document pixels’.
- If you selected ‘Validate element pixels’, select the element you want to validate from your app. The other 2 options don't require DOM selections.
How to add Pixel Wait-for
- Hover the arrow menu where you want to add your wait-for step.
- To add validation click ‘+’ ⇒ ‘Wait for’ ⇒ ‘Wait for element pixel’
- Select the element you want to wait for from your app.
