Unit Testing

This skill should be used when writing, refactoring, or testing Go code. It provides idiomatic Go development patterns, TDD-based workflows, project structure conventions, and testing best practices using testify/require and mockery. Activate this skill when creating new Go features, services, packages, tests, or when setting up new Go projects.

Create detailed implementation plans through an interactive process with research, code snippets, and structured deliverables. Use this skill when planning significant features, refactoring tasks, or complex implementations that require thorough analysis and structured documentation. The skill guides through context gathering, research, design decisions, and generates comprehensive plans with test strategies and success criteria.

Build accessible user interfaces using semantic HTML, proper ARIA attributes, keyboard navigation, color contrast, and screen reader compatibility. Use this skill when creating or modifying frontend components, HTML templates, React/Vue/Svelte components, forms, interactive elements, navigation menus, modals, or any UI elements. Apply when working with HTML files, JSX/TSX components, template files, ensuring keyboard accessibility, implementing focus management, adding alt text to images, creating form labels, testing with screen readers, managing ARIA attributes, maintaining color contrast ratios, or building heading hierarchies. Use for any task involving UI accessibility compliance, WCAG standards, or inclusive design patterns.

Write focused tests for core user flows and critical paths with clear test names, behavior-focused assertions, mocked external dependencies, and fast execution, deferring edge case testing until explicitly required. Use this skill when creating or modifying test files, writing unit tests, integration tests, or test cases for any feature. Apply when writing test files (test/, __tests__/, spec/, .test.js, .spec.ts, test_*.py), implementing tests for core user workflows, testing critical business logic, mocking external dependencies (databases, APIs, file systems), writing descriptive test names, creating fast-running unit tests, or adding tests at logical completion points of feature development. Use for any task involving test creation, test coverage, test strategy, or test-driven development.

Apply Python tooling standards including uv package management, pytest testing, ruff/mypy code quality, one-line docstrings, and self-documenting code practices. Use this skill when working with Python backend code, managing dependencies, running tests, or ensuring code quality. Apply when installing packages, writing tests, formatting code, type checking, adding docstrings, organizing imports, or deciding whether to create new files vs. extending existing ones. Use for any Python development task requiring adherence to tooling standards and best practices.

Build responsive, mobile-first layouts using fluid containers, flexible units, media queries, and touch-friendly design that works across all screen sizes. Use this skill when creating or modifying UI layouts, responsive grids, breakpoint styles, mobile navigation, or any interface that needs to adapt to different screen sizes. Apply when working with responsive CSS, media queries, viewport settings, flexbox/grid layouts, mobile-first styling, breakpoint definitions (mobile, tablet, desktop), touch target sizing, relative units (rem, em, %), image optimization for different screens, or testing layouts across multiple devices. Use for any task involving multi-device support, responsive design patterns, or adaptive layouts.

Maintain and upgrade the bgruening/docker-galaxy project: bump Galaxy/Ubuntu versions, update Ansible roles and scheduler support, adjust startup/CI/tests, and manage CVMFS.

Comprehensive PR review for oc (OpenShift CLI). Runs build, tests, and linting, then applies Go style improvements and provides detailed code review feedback.

Validate injection vulnerabilities including SQL, NoSQL, OS Command, LDAP, XPath, SSTI, and XSS. Test by sending crafted payloads to user-controlled input fields and observing application behavior. Use when testing CWE-89 (SQL Injection), CWE-78 (OS Command Injection), CWE-79 (XSS), CWE-90 (LDAP Injection), CWE-917 (Expression Language Injection), CWE-94 (Code Injection), CWE-643 (XPath Injection), or related injection findings.

Validate authorization failures including IDOR, privilege escalation, and missing access controls. Test by attempting unauthorized access with lower-privileged credentials. Use when testing CWE-639 (IDOR), CWE-269 (Privilege Escalation), CWE-862 (Missing Authorization), CWE-863 (Incorrect Authorization), CWE-284 (Access Control), CWE-285 (Improper Authorization), or CWE-425 (Direct Request/Forced Browsing) findings.

Generate testable hypotheses. Formulate from observations, design experiments, explore competing explanations, develop predictions, propose mechanisms, for scientific inquiry across domains.
