83 plugins for Jest development
Automatically generate production-ready unit tests from source code files or snippets in JavaScript/TypeScript (using Jest, Vitest, or Mocha), Python (pytest), Java (JUnit 5), and Go. Auto-detects frameworks, covers happy paths, edge cases, boundaries, errors, and provides mocks for robust testing.
Orchestrate long-running AI coding sessions that build a persistent project knowledge graph, execute iterative tasks in loop or task modes until completion, generate frontend/backend components/tests/migrations/docs via specialized skills, optimize context with 92% token savings, and self-diagnose collaboration quality issues.
Unlock expert Claude Code skills for TypeScript/JavaScript full-stack development: implement Next.js App Router patterns and Server Components, optimize React apps against 45 performance rules, architect Node.js backends with Hono/Express/NestJS best practices, master async patterns and event loops, and apply advanced TypeScript for monorepos and type-level programming.
Track regression tests across code releases by mapping git commits to pytest or Jest tests, tagging markers for suites, flagging coverage gaps, generating pass/fail reports with flaky detection, viewing history, and enforcing runs in CI/CD pipelines.
Automate overnight software development by configuring Git hooks for TDD enforcement with tests and lints, then run Claude autonomously for 6-8 hours to build features that pass all checks by morning.
Generate complete Jest unit tests for JavaScript/TypeScript modules and React components, automatically including mocking, spies, snapshots, and coverage. Quickly create tests, address missing coverage gaps, or fix improper mocking setups in your codebase.
Generate test reports by parsing JUnit XML, Jest JSON, pytest results, and coverage data into Markdown/HTML formats with metrics, failures, slowest tests, trends, and CI annotations. Aggregate results across frameworks for summaries and exports in HTML, PDF, or JSON.
Orchestrate multi-agent workflows in Claude Code to decompose complex features into parallel subtasks with dependencies, generate and execute TDD tests, discover and load project context, perform automated code reviews for security and quality, and verify implementations before commits.
Enforce TDD workflow by auto-detecting test frameworks like Vitest, Jest, pytest, or Go tests, installing reporters, and outputting results to JSON for status tracking. Hooks block Write/Edit tool calls until tests pass and persist enforcement state across sessions.
Generate unit tests for functions, classes, or modules using your project's Jest or Pytest framework. Automatically mocks dependencies, follows conventions, runs tests, and reports count plus coverage to accelerate testing workflows.
Enforce strict TDD workflow: write minimal failing tests first for complex logic or public APIs, verify red phase failure, implement green-passing code without internal mocks, then refactor safely. Supports unit and integration tests with Jest.
Run automated code quality audits, security scans, test coverage analysis, SOLID/DRY checks, and architecture reviews on Drupal (PHP) or Next.js projects. Auto-detect project type, lint with ESLint/PHPStan, scan with Semgrep/Trivy/Gitleaks, generate prioritized reports, debate findings/improvements with AI agents, setup TDD workflows, and auto-install/configure tools.
