Functional Testing With Artificial Intelligence - Applitools
Functional Testing
Your functional tests pass. Your users still hit bugs.
DOM assertions only check what you thought to check. Applitools adds a single visual check that catches everything else, without adding another brittle selector to maintain.
Write tests faster
Stop writing dozens of assertions to validate one screen. One call to Applitools captures the full page or component and hands it to Visual AI for analysis, so you write one line instead of fifty.
Increase test coverage
Run the same test across every browser and device at once with the Ultrafast Grid and Native Mobile Grid. You get more coverage without standing up local device labs or slowing down your pipeline.
Catch more bugs
Visual AI compares what actually renders, not just what's in the DOM. It catches layout shifts, broken components, and content errors that locator-based assertions never see.
Why is Visual AI the new way to do functional testing?
Cut assertion code down to one line
Capture instead of assert One call, eyes.check, captures your entire page or component and hands it to Visual AI. You stop writing a locator for every element you care about.
Author however you work Write plain English, record a flow, or write code directly in Playwright, Cypress, or Selenium. Assertions live in your framework, so they author naturally in Copilot, Cursor, or Claude.
Know exactly what broke, and why
See the exact change When a test fails, Applitools highlights the specific element that shifted, not a stack trace pointing at a broken selector.
Group related failures Root cause analysis clusters similar diffs across browsers and devices, so one real change doesn't show up as fifty separate failures.
Run functional checks in the pipeline you already have
Test every browser and device at once The Ultrafast Grid and Native Mobile Grid render your app across environments in parallel, without local device labs.
Run in your existing pipeline SDKs integrate directly with Playwright, Cypress, Selenium, and Appium, so visual checks run in the same CI job as the functional tests you already have.
Cut maintenance down to one click
Locator-free execution Elements are found by visual and semantic clues, not CSS or XPath, so a DOM change doesn't break your test.
Auto-maintenance Group related changes across browsers and resolutions, and update every affected baseline with a single click.
What backs up every test result
1
Broad format coverage
The Ultrafast Grid and Native Mobile Grid render the same test across every browser and device in parallel, without a local grid to maintain.
2
Dynamic content handling
Choose the AI algorithm to control what counts as a functional bug, and let Applitools automatically ignore dynamic data like timestamps, session IDs, and A/B content instead of flagging it as a failure.
3
Local AI processing
Visual comparisons run locally within your environment. Page snapshots are never sent to an external model or used for training.
4
Deterministic Language Model
The same input always produces the same output in every locale, every run, so a result is something you can explain and trust.
5
Human-eye simulation
Visual AI ignores rendering noise and flags only the changes a real user would notice, catching functional bugs that pixel-diffing tools miss.
6
Root cause analysis
Click a diff and see the exact DOM and CSS change that caused it, so a failure comes with an answer, not just a red X.
