Automated UI Testing

The problem

UI bugs are the ones users hit first: a button that renders but isn't wired to its handler, a form that submits twice, a modal that won't close, a layout that breaks on a real screen, a flow that dead-ends. Component tests pass, the design looks right in review, and the assembled interface is still broken in ways nobody checked.

Why the usual approach falls short

• Component tests don't test the assembled UI. They check pieces in isolation, not the whole screen wired to real data and real navigation.
• Scripted UI tests are brittle. They break on markup changes that didn't affect what the user sees or does.
• Manual UI checks are inconsistent and don't scale to every release.

How BlackBat AI fits

BlackBat AI drives your actual running interface — clicking real buttons, filling real forms, moving through real flows — and reports what's broken: dead clicks, failed submissions, flows that don't complete, and visual regressions caught from the screenshots it takes along the way. Because it identifies elements by what they do rather than by a selector, a restyled component or restructured DOM doesn't break coverage.

For specific UI flows that must always work, describe them in plain English and BlackBat AI checks them every run.

This sits on top of component testing, not instead of it — keep React Testing Library, Storybook, and the rest for isolated component behaviour. See how to test a React app end to end for the layered picture.

What your first run looks like

1. Point BlackBat AI at the running app with a test account.
2. Watch it exercise the interface; findings appear as it goes.
3. Review the bug list — each UI issue has a screenshot and reproduction steps.

The kinds of UI problems it finds

• Dead clicks: an element that renders and looks fine but does nothing when clicked.
• Failed submissions: forms that error, hang, or submit twice.
• Flows that dead-end: a step that doesn't lead anywhere, or a modal that won't close.
• Visual changes: a page that renders differently from a previous run, caught from the screenshots BlackBat AI takes as it goes.
• Error states: pages that show an error instead of content.

Each finding includes a screenshot of the moment it broke and the steps that led there, so you can retrace it in a browser in a minute. The guide to reviewing a run covers sorting real issues from expected behavior.

What UI testing here doesn't cover

• Pixel-exact design review. A person still decides whether something looks right. BlackBat AI tells you when something changed or broke.
• Isolated component states. Use Storybook or component tests for each variant of a component.
• Accessibility audits. Use dedicated accessibility tooling alongside it.

Where it fits

Component tests for pieces, BlackBat AI for the assembled interface, a small scripted set for exact visual or behavioural assertions. The end-to-end testing guide covers the wider strategy.
