Use this skill when writing Go tests with stretchr/testify, implementing TDD workflows, creating mocks, or organizing test suites. Covers assert vs require patterns, interface mocking, table-driven tests, and the red-green-refactor cycle.
Verify implementation completeness against spec and tasks. Use after implementation to ensure all tasks are complete, tests pass, and code meets quality standards before marking feature done.
Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior and production pollution
Advanced pytest patterns including fixtures, markers, plugins, and async testing. Use when implementing test infrastructure, organizing test suites, using pytest plugins, or setting up complex test scenarios with fixtures and parametrization. Triggered by: pytest, fixtures, parametrize, conftest, test organization, async testing.
Test smart contracts comprehensively using Hardhat and Foundry with unit tests, integration tests, and mainnet forking. Use when testing Solidity contracts, setting up blockchain test suites, or validating DeFi protocols.
Assists with testing Aztec smart contracts using the TestEnvironment. Use when writing unit tests, integration tests, or debugging test failures for Aztec contracts.
Generate Jest end-to-end tests for Aztec contracts with real network interaction. Use when writing integration tests, testing contract deployments, or validating full transaction flows.
Master test planning with test strategies, test plans, scope definition, and comprehensive testing approaches.
Prompt testing, metrics, and A/B testing frameworks
Design comprehensive test strategies with risk-informed prioritization (P0/P1/P2), test levels (unit/integration/E2E), mock strategies, and CI/CD integration. Creates Given-When-Then scenarios for all acceptance criteria, develops mock strategies for external dependencies, and plans CI/CD execution stages. Use during task planning before implementation to ensure comprehensive test coverage.
QA specialist agent for test planning, execution, and regression analysis
Meta-validation skill that generates edge cases, production scenarios, and reality gaps not covered by original specifications. Identifies specification-reality mismatches by analyzing what tests claim versus what production data reveals. Creates test deficiency reports showing coverage gaps for Quinn review. Use before quality gate approval to ensure tests reflect production reality, not just specification compliance.
Complete feature development lifecycle from task selection through commit. Orchestrates component design, build loops with browser testing, PostHog analytics, and documentation updates. Use when building any new feature or enhancement.
Use to design test strategies and create test specifications. Documents testing approaches for stories.
This skill should be used when executing plan tasks autonomously, implementing features using TDD, running the red-green-refactor cycle, handling code review loops, or dealing with blocked tasks. Provides the autonomous TDD execution workflow.
This skill should be used when users want to create new UIs, improve existing UIs, compare UI variations (A/B testing), or build component libraries. Combines visual design principles with code implementation (React/Vue) and Playwright-based evaluation to objectively assess UI quality through accessibility audits, performance metrics, and visual regression testing. Use when tasks involve UI design, component creation, accessibility testing, or design system development.
Guide for writing high-quality acceptance criteria and acceptance tests using industry-standard BDD (Behavior-Driven Development) and ATDD (Acceptance Test-Driven Development) practices. Use this skill when creating acceptance criteria for user stories, writing Gherkin scenarios, or implementing acceptance test specifications following Given-When-Then format.
Testing and validation specialist - handles test suite execution, mobile UX validation, accessibility checks, and pre-deployment QA.
Automates the creation of behavior-driven, fail-first feature tests for user-facing behaviors. Works across any language or framework. Use when features lack behavioral tests, implementing fail-first TDD, ensuring user-facing functionality has comprehensive test coverage, or when the user mentions BDD, feature tests, or user behavior testing.
