Unit Testing

How tests should be structured, named, and prioritized in this codebase.

Webhook validation patterns with signature verification, event logging, and testing tools. Use when implementing webhooks, validating webhook signatures, securing payment webhooks, testing webhook endpoints, preventing replay attacks, or when user mentions webhook security, Stripe webhooks, signature verification, webhook testing, or event validation.

Factory.ai Droid CLI integration for autonomous AI coding agent. Supports interactive and exec modes with multiple autonomy levels for code review, feature development, and testing. Activated when users need terminal-based AI assistance for comprehensive code tasks.

Generate optimized indirect prompt injection, H-CoT, and multi-layer attack payloads for AI security testing and CTF competitions with automated family selection and success rate optimization

Production-grade accessibility skill for WCAG 2.2 AA compliance.Covers auditing, remediation, component authoring, and validation workflows.Auto-invoked for UI implementation, a11y fixes, and accessibility testing.

End-to-end testing patterns for backend services. Use when testing complete application flows.

Use when building a production-ready REST API from requirements through deployment.Orchestrates 8-12 specialist agents across 5 phases using Test-Driven Development methodology.Covers planning, architecture, TDD implementation, comprehensive testing, documentation, andblue-green deployment over a 2-week timeline with emphasis on quality and reliability.

Analyze and fix CI/CD pipeline failures including build errors, test failures, and linting issues

Use when generating PDFs from markdown with Pandoc - covers differences from Python-Markdown, blank line rules, fix scripts for labels/anchors/metadata, and visual testing workflow

Conversion rate optimization (CRO) patterns for Next.js applications including CTA design, landing page layouts, trust signals, form optimization, pricing tables, and A/B testing. Use when building landing pages, optimizing CTAs, adding social proof, or improving conversion funnels.

Comprehensive plugin development toolkit for creating, testing, and managing plugins across multiple platforms with scaffolding, validation, and deployment utilities.

Infer and verify install/test/lint/build commands for the repo.

Use to validate process documentation. Apply TDD to skill writing: RED (run without skill, document failures) → GREEN (write skill) → REFACTOR (close loopholes). Test under pressure: time constraints, sunk cost, exhaustion, authority.

Evaluate accessibility and WCAG compliance of UI components and pages. Use when the user asks to "check accessibility", "audit a11y", "WCAG review", "screen reader test", or needs to verify inclusive design practices.

Guide developers through property-based testing including property definition, shrinking, and framework-specific implementation

AWS infrastructure as code with Terraform and CDK, including VPC design, EKS cluster setup, S3 bucket configuration, RDS databases, DynamoDB tables, Lambda functions, API Gateway, CloudWatch monitoring, IAM policies, security groups, cost optimization, multi-account strategies, CI/CD with CodePipeline, infrastructure testing, disaster recovery, compliance automation, and cloud-native best practices for production workloads.

Run comprehensive Rust code quality checks including compilation, linting, documentation, and tests. Use after completing code changes and before creating commits.

Use when creating Python projects, managing dependencies with uv, configuring pyproject.toml, building packages, or publishing to PyPI - covers project initialization, dependency management, and distribution; NOT for testing or performance (plugin:python@dot-claude)

How to run swift unit tests

Cross-language testing patterns: unit, integration, E2E testing strategies.Use when: writing tests, setting up test infrastructure, or improving coverage.Triggers: "test", "testing", "unit test", "integration test", "e2e","coverage", "mock", "fixture".
