Under the hood of ClickTrails – the engine behind exhaustive UI exploration and automated test coverage.

Core Technologies

1. Playwright + Headless Browsers

We use Playwright as our test runner and automation engine, enabling fast, reliable interaction with every element on your web app — across Chromium, Firefox, and WebKit.

2. JavaScript/TypeScript Backend

ClickTrails is powered by a modern TypeScript backend, enabling fast API responses, clean data flow, and safe, scalable logic for crawling and test generation.

3. WebSocket Communication

Live browser sessions are controlled via WebSocket for real-time feedback, control, and visual updates as the UI is crawled.

4. React + Tailwind (Frontend)

Our UI is built in React, styled with Tailwind, and optimized for clarity — from dynamic tree graphs to detailed test reporting dashboards.

5. Graph Theory & Tree Traversal Algorithms

We use graph-based modeling of your application's DOM states and routes. Interactions are stored as nodes and edges, allowing us to traverse all reachable paths and identify edge cases automatically.

6. State Snapshotting + Replay

Each test step captures UI state and context. This enables test replay, custom assertion insertion, and diffing to detect regressions over time.

Core Methods & Workflow

1. Interaction Crawler

ClickTrails launches your web app in a sandbox and systematically clicks through all buttons, links, and form fields. Each interaction is tracked and mapped.

2. Dynamic Path Mapping

We build a real-time tree graph representing all reachable user paths. This gives you full visibility into how users (and testers) can traverse the app.

3. Assertion Injection

You can enhance any point in the test tree with assertions — DOM existence, text, state, or visual diffs — to validate intended behavior.

4. Smart Path Pruning

To avoid redundant or infinite loops, we use heuristics and path history to intelligently skip or end test paths that lead to repetition.

5. Test Suite Generation

All discovered paths can be saved and exported into a runnable test suite. Re-run the suite anytime with your CI/CD pipeline.

6. Visual Feedback & Logs

Each click path is visualized, and detailed logs are captured with screenshots and metadata for debugging and regression testing.
