description	Guidelines for testing using Playwright and Chrome DevTools

Overview

Use Playwright MCP for end-to-end testing and Chrome DevTools for debugging. Follow page-specific test instructions in .github/instructions/page.<page-name>.instructions.md files for detailed testing procedures.

General Testing Workflow

• Start by navigating to the application URL
• Follow the test instructions for each page in the corresponding instruction file
• Use snapshots to verify UI state before and after interactions
• Check console messages for errors during testing
• Validate local storage changes when applicable

Page-Specific Testing Instructions

Refer to these instruction files for detailed test procedures for each page:

• page.home.instructions.md - Home page navigation and initial setup
• page.create-game.instructions.md - Game creation workflow
• page.saved-games.instructions.md - Saved games management
• page.custom-game-modes.instructions.md - Custom game modes handling
• page.play.instructions.md - Game playing interface
• page.game-summary.instructions.md - Post-game summary display
• page.campaign-games.instructions.md - Campaign games listing
• page.start-campaign.instructions.md - Campaign initialization
• page.continue-campaign.instructions.md - Campaign continuation
• page.campaign-upgrade.instructions.md - Campaign progression
• page.not-found.instructions.md - Error page handling

Testing Tools and Commands

• Use mcp_playwright_browser_navigate to navigate to different pages
• Use mcp_playwright_browser_click to interact with buttons and links
• Use mcp_playwright_browser_snapshot to capture page state for verification
• Use mcp_playwright_browser_console_messages to check for JavaScript errors
• Use mcp_playwright_browser_tabs to manage browser tabs during testing
• Use mcp_chrome-devtoo_emulate to test different device configurations

Common Test Patterns

• Navigation Testing: Verify that clicking navigation elements takes you to the correct page
• Form Testing: Fill out forms and verify submission works correctly
• Modal Testing: Test modal opening, interaction, and closing
• Game State Testing: Verify game objects appear and behave correctly
• Local Storage Testing: Check that data persists between sessions
• Error Handling: Test invalid inputs and error states

Validation Steps

• Always take snapshots before and after major interactions
• Check that expected elements are present on the page
• Verify that buttons and links have the correct text labels
• Ensure console is free of errors during normal operation
• Test both success and failure scenarios

Debugging During Testing

• Use Chrome DevTools to inspect elements and check local storage
• Monitor network requests with mcp_playwright_browser_network_requests
• Check console messages for warnings and errors
• Use browser evaluation with mcp_playwright_browser_evaluate for complex checks

Test Data Management

• Create test games and campaigns for consistent testing
• Use local storage to maintain test state between sessions
• Clean up test data when necessary to avoid interference

Autonomous Testing Guidelines

• Follow the bullet-point instructions in each page's instruction file exactly
• Use exact button and link text labels as specified in the instructions
• Take snapshots at key points to verify expected state changes
• Report any deviations from expected behavior
• Test edge cases and error conditions when possible
