Copy this and paste it into Claude Code, Cursor, or any AI assistant:
I want to add the "shopsys — Cursor Rules" prompt rules to my project. Repository: https://github.com/shopsys/shopsys Please read the repo to find the rules/prompt file, then: 1. Download it to the correct location (.cursorrules, .windsurfrules, .github/prompts/, or project root — based on the file type) 2. If there's an existing rules file, merge the new rules in rather than overwriting 3. Confirm what was added
Description
Testing frameworks and essential testing patterns
Before Refactoring/Changes
Always check for existing tests before making significant changes: • Analyze existing code - Check if the code being modified has tests • If no tests exist - Ask user: _"I notice there are no tests for [component/function] that I'm about to refactor. Would you like me to create tests first to ensure the refactoring doesn't break existing functionality?"_ • After user confirmation - Create baseline tests that verify current behavior • Proceed with changes - Make the refactoring/modifications • Verify tests pass - Ensure changes don't break functionality
After New Implementation
Always offer to create tests for new functionality: • After implementing new features - Ask user: _"I've implemented [feature/component]. Would you like me to create tests for this new functionality? This would include [unit/component/integration] tests to ensure reliability."_ • After user confirmation - Create comprehensive tests covering the new code
When to Apply This Workflow
• ✅ New components, hooks, utilities • ✅ Business logic or data processing • ✅ API endpoints or GraphQL resolvers • ✅ Complex refactoring • ✅ Bug fixes that add new logic • ❌ Minor styling changes • ❌ Text/copy updates • ❌ Simple configuration changes
