單元測試

Build comprehensive GitHub Actions workflows for CI/CD, testing, security, and deployment. Master workflows, jobs, steps, and conditional execution.

Main orchestrator for the 6-gate development cycle system. Loads tasks/subtasksfrom PM team output and executes through implementation, devops, SRE, testing, review,and validation gates with state persistence and metrics collection.

Implement WCAG 2.1/2.2 accessibility standards, screen reader compatibility, keyboard navigation, and a11y testing. Use when building inclusive web applications, ensuring regulatory compliance, or improving user experience for people with disabilities.

Ethical hacking and security testing methodologies using penetration testing tools, exploit frameworks, and manual security validation. Use when assessing application security posture and identifying exploitable vulnerabilities.

Implement comprehensive frontend testing using Jest, Vitest, React Testing Library, and Cypress. Use when building robust test suites for UI and integration tests.

Verify API contracts between services to ensure compatibility and prevent breaking changes. Use for contract testing, Pact, API contract validation, schema validation, and consumer-driven contracts.

Comprehensive mobile app testing strategies for iOS and Android. Covers unit tests, UI tests, integration tests, performance testing, and test automation with Detox, Appium, and XCTest.

Design property-based tests that verify code properties hold for all inputs using automatic test case generation. Use for property-based, QuickCheck, hypothesis testing, generative testing, and invariant verification.

Design and analyze A/B tests, calculate statistical significance, and determine sample sizes for conversion optimization and experiment validation

Test web applications for WCAG compliance and ensure usability for users with disabilities. Use for accessibility test, a11y, axe, ARIA, keyboard navigation, screen reader compatibility, and WCAG validation.

Design and execute performance tests to measure response times, throughput, and resource utilization. Use for performance test, load test, JMeter, k6, benchmark, latency testing, and scalability analysis.

Execute comprehensive disaster recovery tests, validate recovery procedures, and document lessons learned from DR exercises.

Detect unintended visual changes in UI by comparing screenshots across versions. Use for visual regression, screenshot diff, Percy, Chromatic, UI testing, and visual validation.

RED-GREEN-REFACTOR implementation methodology - write failing test first,minimal implementation to pass, then refactor. Ensures tests verify behavior.

Create and manage mocks, stubs, spies, and test doubles for isolating unit tests from external dependencies. Use for mock, stub, spy, test double, Mockito, Jest mocks, and dependency isolation.

Conduct statistical tests including t-tests, chi-square, ANOVA, and p-value analysis for statistical significance, hypothesis validation, and A/B testing

Implement feature flags (toggles) for controlled feature rollouts, A/B testing, canary deployments, and kill switches. Use when deploying new features gradually, testing in production, or managing feature lifecycles.

Gate 3 of development cycle - ensures unit test coverage meets threshold (85%+)for all acceptance criteria using TDD methodology.

Integrate automated testing into CI/CD pipelines for continuous quality feedback. Use for continuous testing, CI testing, automated testing pipelines, test orchestration, and DevOps quality practices.

Implement backup and restore strategies for disaster recovery. Use when creating backup plans, testing restore procedures, or setting up automated backups.
