SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates manual browser testing and exploratory QA by enabling AI agents to interact with web pages, reducing brittle scripts, manual repro steps, and slow feedback loops.

Core Features & Use Cases

  • Autonomous Exploration: Agents navigate pages, click elements, fill forms, and probe edge cases without prewritten test scripts.
  • Structured Reporting: JSON output mode and accessibility-tree snapshots provide machine-readable results for downstream analysis.
  • Repro Capture & Debugging: Capture screenshots, step-by-step traces, and video repros for triage and bug reports.
  • Use Case: Run autonomous QA on a staging site to detect regressions, reproduce bugs, and generate prioritized reports for engineers.

Quick Start

Use the agent-browser CLI to open a target URL, explore interactions autonomously, and output a JSON report.

FAQPage Schema
How do I automate headless browser testing for web pages without writing brittle scripts?

Autonomous headless browser testing uses a lightweight CLI to let AI agents navigate pages, click elements, fill forms, and probe edge cases without prewritten test scripts. This reduces brittle scripts and manual repro steps by enabling agent-driven exploratory QA.

Can I get machine-readable JSON output for agents from headless Chromium orchestration?

Yes, headless Chromium orchestration provides a JSON output mode and accessibility-tree snapshots. This delivers structured reporting for downstream analysis, allowing agents to process machine-readable results from autonomous QA sessions.

How do I capture repro steps and debug regressions on a staging site?

Use headless browser interaction to capture screenshots, step-by-step traces, and video repros for triage and bug reports. You can run autonomous QA on a staging site to detect regressions, reproduce bugs, and generate prioritized reports for engineers.

Does autonomous QA work with single-page applications and session persistence?

Yes, autonomous QA supports exploratory testing across websites and single-page applications. It satisfies requirements for session persistence and optional CDP connectivity, allowing agents to maintain state during extended interaction and probing workflows.

What is the best way to run accessibility audits and exploratory QA across websites?

The best way to run accessibility audits is through agent-driven testing that uses semantic locators to interact with web pages. This approach automates manual browser testing, providing accessibility-tree snapshots to evaluate compliance and detect edge cases.

Do I need prewritten test scripts to perform headless browser interaction?

No, you do not need prewritten test scripts to perform headless browser interaction. Agents navigate pages and explore interactions autonomously, which eliminates the need for manual repro steps and reduces slow feedback loops.
