Test
Run comprehensive test suites with parallel unit, integration, and E2E execution
What You Can Do
You can orchestrate a complete testing strategy that balances speed with thoroughness. Claude runs type diagnostics first to catch root causes, executes unit and integration tests in parallel for efficiency, then sequences E2E tests only after faster tests pass. This workflow prevents wasted time on slow tests when foundational issues exist.
Features
Type checks before test execution to identify root causes instantly
Runs unit and integration tests simultaneously for faster feedback
Triggers end-to-end tests only after unit/integration tests pass
Organized workflow from fast tests to slow tests
Identifies which test layer failed and why, not just that tests failed
Optional detection of affected tests based on code changes
Visual test results organized by phase and agent responsibility
Example Output
Example 1: Full test pass
Phase 0: Diagnostics ✓ (0 errors)
Phase 1: Unit Tests ✓ (24 passed)
Phase 1: Integration Tests ✓ (8 passed)
Phase 2: E2E Tests ✓ (6 passed)
All tests passed in 47 seconds
Example 2: Type error caught early
Phase 0: Diagnostics ✗
Error: Expected int, got str at src/utils.ts:12
Error: Missing required property 'id' at src/models.ts:35
→ Fix type errors before running tests (estimated 2 min)
Example 3: Integration test failure
Phase 0: Diagnostics ✓ (0 errors)
Phase 1: Unit Tests ✓ (24 passed)
Phase 1: Integration Tests ✗ (1 failed: Database connection)
→ E2E tests skipped (integration layer unstable)

You might also like
You get Claude to analyze your API specifications and automatically generate bulletproof parameter validation logic. Claude creates security-hardened middleware, enforces type constraints, detects malicious input patterns, and generates comprehensive error handling — all tailored to your framework and existing codebase. The result is production-ready validation code with zero unvalidated inputs reaching your business logic.
This skill enables you to automatically audit your websites against compliance standards and detect deviations from expected baselines. You can track regulatory requirements, identify policy violations, and generate compliance reports with actionable remediation steps. Monitor multiple sites simultaneously and maintain detailed audit trails for compliance documentation.
Transform schema and data changes into production-ready migration packages that protect data integrity and minimize downtime. You can handle column additions, renames, type conversions, and backfills using proven patterns like expand-contract and shadow tables. The skill generates explicit rollback scripts, validation checklists, and phased execution plans that keep applications stable throughout the migration.
You'll transform high-level feature requirements into a complete development plan covering API design, frontend implementation, testing strategy, and documentation. The skill helps you identify dependencies, parallelize work across frontend and backend teams, and establish quality gates that ensure features ship bug-free with proper error handling and logging.
You can conduct comprehensive toxicology safety assessments, generate regulatory-compliant safety documentation, and produce detailed hazard analyses for pharmaceutical and chemical submissions. This skill structures toxicological data into standardized safety reports, maps findings to regulatory guidelines (FDA, EMA, ICH), and identifies risk characterization strategies to support regulatory submissions and approval timelines.
You can submit your Solidity smart contracts for comprehensive security analysis, vulnerability detection, and gas optimization recommendations. Claude reviews your code against known attack vectors, design patterns, and best practices—identifying reentrancy risks, overflow/underflow issues, access control flaws, and inefficient operations. You receive actionable fix recommendations with explanations of the security implications and gas savings potential.
You can design end-to-end NGS pipelines tailored to your experiment type (WGS, WES, RNA-seq, targeted), troubleshoot pipeline failures by analyzing QC metrics and logs, and optimize performance by fine-tuning parameters and identifying bottlenecks. This skill handles the full workflow from raw sequencing data quality assessment through variant interpretation and annotation.
You can accelerate your entire antenna design workflow—from initial concept to optimized specifications—by leveraging Claude's knowledge of electromagnetic theory, antenna types, and design trade-offs. Claude helps you parameterize designs, identify optimal configurations for your frequency band and application, and prepare detailed briefs for simulation and manufacturing. You'll generate design reviews, impedance-matching solutions, and validation checklists without context-switching to multiple tools.
