Autonomous web app testing with agent-browser — auto-discovery, structured flows, exploratory testing, and bug reporting
Run autonomous exploratory browser testing. Use when user says "explore the app", "find bugs", "test everything", "autonomous testing", or wants the agent to freely navigate and discover issues without predefined test flows.
Generate a test report from the most recent results. Use when user says "generate report", "show test results", "create test report", or wants to view or share the results of a previous test run.
Install agent-browser and discover app configuration. Use when user says 'set up browser testing', 'install agent-browser', or wants to initialize browser testing for a web project.
Run structured browser test suite. Use when user says "test the app", "run browser tests", "check if the UI works", "verify routes", or wants to run the full structured test suite against discovered routes.
Discover web app configuration from codebase. Use when setting up browser testing, detecting dev server commands, mapping routes, or identifying authentication flows for a web application project.
Generate test reports and create GitHub issues from browser test results. Use when test results exist at test-reports/results.json and a formatted report or bug issues are needed.
Execute browser tests using agent-browser. Use when running structured test flows against discovered routes, performing autonomous exploratory testing, or verifying web app behavior after code changes.
agent-browser usage patterns and conventions reference. Use when agents or commands need agent-browser context, ref-based workflow, session persistence, semantic locator fallbacks, or error handling patterns.
Testing conventions and configuration reference. Use when agents or commands need config schema, severity classification, report templates, or credential rules for browser testing.
