Testing & Security

Use when adding automated tests to CocoaPods libraries using test specs. Covers test spec configuration, app host requirements, and testing patterns that integrate with pod lib lint validation.

Use when advanced Cypress features including custom commands, plugins, and network stubbing.

Use when vitest configuration, Vite integration, workspace setup, and test environment configuration for modern testing.

Use when building modular Angular applications requiring dependency injection with providers, injectors, and services.

Use when mocha configuration including reporters, config files, plugins, and CI integration.

Use when assertion libraries for Mocha including Chai with expect, should, and assert styles.

Use when implementing data-driven tests with TestNG DataProviders, factory methods, and parameterization patterns.

Use when advanced Pytest features including markers, custom assertions, hooks, and coverage configuration.

Master FastAPI dependency injection for building modular, testable APIs. Use when creating reusable dependencies and services.

Use when jest configuration, setup files, module resolution, and project organization for optimal testing environments.

Validates audio plugins through automated tests, pluginval, or manual DAW testing. Use for MANUAL testing via /test command. Note - Automatic validation now built into workflow (validation-agent runs after each stage). This skill is for manual testing only, after bug fixes, or when user mentions test, validate, validation, pluginval, stability, automated tests, run tests, check plugin, or quality assurance.

Use when creating custom Ameba rules for Crystal code analysis including rule development, AST traversal, issue reporting, and rule testing.

Use when applying Behavior-Driven Development patterns including Given-When-Then structure, feature files, and acceptance criteria. Use when writing BDD-style tests and specifications.

Use when Effect dependency injection patterns including Context, Layer, service definitions, and dependency composition. Use for managing dependencies in Effect applications.

Use when essential PHP security patterns including input validation, SQL injection prevention, XSS protection, CSRF tokens, password hashing, secure session management, and defense-in-depth strategies for building secure PHP applications.

Use when testing Effect code including Effect.gen in tests, test layers, mocking services, and testing error scenarios. Use for writing tests for Effect applications.

Use when restructuring code to improve quality without changing external behavior. Emphasizes safety through tests and incremental changes.

Writing effective step definitions and organizing test code

Use when implementing GraphQL resolvers with resolver functions, context management, DataLoader batching, error handling, authentication, and testing strategies.

Use when writing shell scripts following modern best practices. Covers portable scripting, Bash patterns, error handling, and secure coding.
