Self-Test Skill

Pattern for iterative testing during implementation.

When to Load This Skill

• You are implementing code
• You need to verify your work before completing
• You want to catch issues early

Self-Test Loop

CopyWHILE implementation not complete:
    Write/modify code
        ↓
    Write tests for new code
        ↓
    Run tests
        ↓
    FAIL? → Fix code, retry
        ↓
    Run lint
        ↓
    FAIL? → Fix issues, retry
        ↓
    Run typecheck
        ↓
    FAIL? → Fix types, retry
        ↓
    Continue to next piece

Running Tests

Use project-specific test commands: @.claude/skills/project/run-tests/SKILL.md

Common patterns:

Copy# Run specific test file
npm test -- --testPathPattern={file}
pytest {file} -v

# Run affected tests
npm test -- --changedSince=HEAD

Running Lint/Typecheck

Use project-specific commands: @.claude/skills/project/lint/SKILL.md

Common patterns:

Copy# TypeScript
npx tsc --noEmit
npx eslint {files} --fix

# Python
mypy {files}
ruff check {files} --fix

Before Declaring Pre-Complete

Checklist:

• New code has tests
• All tests pass
• Lint passes
• Typecheck passes
• No console errors/warnings

If ANY fails, status is NOT pre_complete.

Principles

• Test as you go - Don't batch at the end
• Fix immediately - Don't accumulate failures
• Be honest - Report actual status
