webapp-testing

The webapp-testing skill provides a structured framework for software agents to perform end-to-end testing and reconnaissance on local web applications. By leveraging Playwright, it enables programmatic control over browser instances, making it ideal for developers, quality assurance engineers, and AI agents tasked with validating frontend components or debugging UI behavior in development environments. The skill is designed to handle the complexities of modern web stacks, including dynamic rendering, network synchronization, and multi-server orchestration.

• Automated browser orchestration using Python Playwright, including headless execution for efficiency.

• Lifecycle management for local development servers, supporting complex setups with multiple backend and frontend services.

• Visual debugging and DOM inspection capabilities, including full-page screenshots and content extraction for selector identification.

• Built-in support for network idle waiting patterns to ensure reliability when interacting with JavaScript-heavy frameworks.

• Console log capture and analysis for troubleshooting runtime errors during automated sequences.

• Ensure you check the help documentation for helper scripts before writing custom automation logic to avoid redundant work.

• Always wait for 'networkidle' states when dealing with dynamic web applications to ensure the DOM is fully rendered before inspection or interaction.

• Utilize specific selectors like role-based, text-based, or CSS IDs for robust test scripts; avoid relying on fragile XPaths.

• Use the bundled 'scripts/with_server.py' utility to manage server lifecycle, which prevents dangling processes and ensures consistent environmental state.

• Treat provided helper scripts as black-box tools to minimize context window consumption; only read the source code if absolutely necessary for custom debugging.

• Ideal for use cases including automated visual regression testing, validating form interactions, verifying user flows, and general frontend component assessment.
