Automated Testing Suite Generator

Generate comprehensive tests that actually catch bugs.

What It Creates

Unit Tests

• Function input/output validation
• Edge cases (null, undefined, empty, boundary values)
• Error handling paths
• Mock generation for dependencies

Integration Tests

• API endpoint testing (all methods, status codes)
• Database query validation
• Authentication flow testing
• Webhook handler testing

E2E Tests (Playwright)

• User flow scenarios
• Form submission and validation
• Navigation and routing
• Responsive layout checks

Usage (illustrative custom-wrapper commands)

These are not built-in Claude Code subcommands. They require a custom wrapper; consult the wrapper's documentation before use.

# Generate tests for a specific file
claude test-gen src/lib/auth.ts

# Generate tests for entire directory
claude test-gen src/api/ --framework jest

# Generate E2E tests from user stories
claude test-gen --e2e "User can register, login, and update profile"

# Generate tests for uncovered code
claude test-gen --coverage --min 80

Smart Analysis

The generator:

• Reads your existing test patterns and follows them
• Identifies untested code paths via static analysis
• Generates realistic test data (not just "foo" and "bar")
• Creates proper test isolation (setup/teardown)
• Handles async code correctly
