How do you do visual regression testing with AI?
Because the agent sees your app the way a user does, it notices meaningful visual problems – broken layouts, wrong spacing, missing elements – during normal runs, without pixel-diffing every screen. You can also assert specific visual states in plain language.
Sub-use-cases
Covers Layout-break detection after upgrades, explicit visual-state assertions, cross-page visual consistency, dark-mode/theme checks and automated visual regression in CI.
- 01
What visual testing catches
Layout integrity after CSS or dependency changes, component rendering, spacing and alignment, colour and contrast, and visual consistency across pages, states and themes.
- 02
How does AI spot a visual regression?
The agent evaluates the rendered UI visually each run; for explicit checks you describe the expected appearance ("the primary button should be blue by default") and it verifies that visually. Step screenshots double as a visual record.
- 03
When visual checks matter most
After design-system migrations, dependency upgrades, or any CSS-heavy change – and continuously alongside functional tests.
- 04
Who needs visual regression testing
Teams burned by layout regressions, and anyone running a separate pixel-diff tool today.
- 05
How QA.tech helps
Pixel-diff tools flag every change, creating noise teams learn to ignore. QA.tech's visual understanding surfaces problems that matter, as a byproduct of tests you already run – no extra tool to maintain.

FAQ
Common questions
- How is this different from Percy, Applitools or Chromatic?
- Those pixel-diff screenshots and flag every change; QA.tech judges the UI visually, so intentional cosmetic changes don't drown you in false positives.
- Can I assert a specific colour or state?
- Yes – describe the expected visual state and the agent checks for it.
- Do I need a separate visual testing tool?
- No – visual checks run within your normal functional tests.

Account & Profile Settings Testing
An AI agent runs every settings action a user can take – update profile fields, change email and password, upload an avatar, toggle preferences – then verifies the changes persist after a refresh. Settings pages look simple but touch storage, auth and email, so they regress quietly.
ReadAuthentication & Login Flow Testing
An AI agent runs your real login journeys – including the parts traditional tools can't, like opening an email or reading an SMS code – and verifies the user ends up authenticated. QA.tech gives the agent its own inbox and phone number, so magic links, one-time passwords and confirmation emails are tested end to end, not mocked. See how Upsales replaced 320 hours of manual testing a month with this approach.
ReadAutomated Accessibility (WCAG) Testing
Every QA.tech test run automatically checks for WCAG accessibility issues and logs them alongside functional findings – so accessibility coverage happens as a byproduct of testing you already do, with no separate tool or configuration.
