Tool Priorities

ALWAYS prioritize mcp__serena__ tools over default Claude Code tools:

File Operations (Serena MCP First)

• Reading files: Use mcp__serena__find_file → Read (fallback)
• Searching patterns: Use mcp__serena__search_for_pattern → Grep (fallback)
• Finding symbols: Use mcp__serena__find_symbol → Glob (fallback)

Code Analysis (Serena MCP)

• Symbol overview: Use mcp__serena__get_symbols_overview
• Symbol references: Use mcp__serena__find_referencing_symbols
• Code replacement: Use mcp__serena__replace_symbol_body → Edit (fallback)

Examples

# Basic Usage
/test LoginComponent -e -r          # E2E tests, run & fix
/test utils/auth -u -r -c           # High-coverage unit tests
/test PaymentForm -e -v             # E2E with verbose output

# File Pattern Specification
/test components --files="Button*" -u -r
/test src --files="**/*.hook.ts" -u -c
/test api --files="**/*Controller.ts" --include-deps -u -r

# Performance-Focused
/test heavyComponent -u -p -f --parallel=8
/test api/bulk -u -p --timeout=60

Test Implementation Flow

Unit Test Mode (-u)

1. Target code analysis with Serena MCP
2. Test framework detection (Jest, Vitest, Mocha)
3. Test case creation: happy path, error cases, edge cases

E2E Test Mode (-e)

1. Component analysis for interactive elements
2. E2E framework detection (Cypress, Playwright)
3. Accessibility attribute injection (data-testid, aria-label)
4. E2E test case creation: page loading, user interactions, forms

Smart Fixing (-r option)

1. Parse error output
2. Classify errors: syntax, assertion, async, mock, E2E-specific
3. Apply appropriate fixing strategy
4. Re-run and iterate (max 10 attempts)
