# Testing Strategy ## Purpose Design comprehensive test strategies with test pyramid coverage, test file structure, and quality gates. ## Scope Constraints - Covers test plan design, pyramid layering, coverage targets, and CI quality gates. - Does not cover codebase pattern auditing or convention enforcement — hand off to pattern-analysis. - Does not cover architectural decisions about system boundaries — hand off to architect department. ## Inputs - Feature description and scope - Existing test infrastructure (framework, runner, coverage tools) - CI/CD pipeline details (if relevant) - Existing test conventions in the codebase - Coverage targets or requirements (if any) ## Input Sanitization No user-provided values are used in commands or file paths. All inputs are treated as read-only analysis targets. ## Procedure ### Progress Checklist - [ ] Step 1: Audit existing test infrastructure - [ ] Step 2: Identify testable units - [ ] Step 3: Design test pyramid - [ ] Step 4: Write test specifications - [ ] Step 5: Define coverage targets - [ ] Step 6: Plan quality gates ### Step 1: Audit Existing Test Infrastructure - Test framework (Jest, Vitest, Playwright, Cypress, etc.) - Test runner and configuration - Coverage tools (Istanbul, c8, etc.) - CI integration (GitHub Actions, etc.) - Existing test patterns (file location, naming, describe/it structure) - Existing mocking patterns (jest.mock, vi.mock, MSW, etc.) ### Step 2: Identify Testable Units From the feature,
