Build Your Testing Skill
Create your agent-tdd skill in one prompt, then learn to improve it throughout the chapter
Best use case
Build Your Testing Skill is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Create your agent-tdd skill in one prompt, then learn to improve it throughout the chapter
Teams using Build Your Testing Skill should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.

# Build Your Testing Skill Before learning how to test AI agents, you'll **own** a testing skill. This chapter teaches TDD (Test-Driven Development) for agent code—the deterministic tests that verify your code works correctly, runs fast, and costs nothing. By the end, you'll have a comprehensive test suite for your Task API with 80%+ coverage and zero LLM API calls during testing. But you won't learn testing patterns and then maybe build a skill later. You'll build the skill **first**, then spend the chapter improving it with every lesson. --- ## Step 1: Get the Skills Lab 1. Go to [github.com/panaversity/claude-code-skills-lab](https://github.com/panaversity/claude-code-skills-lab) 2. Click the green **Code** button 3. Select **Download ZIP** 4. Extract the ZIP file 5. Open the extracted folder in your terminal ```bash cd claude-code-skills-lab claude ``` --- ## Step 2: Create Your Skill Copy and paste this prompt: ``` Using your skill creator skill create a new skill for testing AI agent code with pytest. I will use it to test FastAPI endpoints, mock LLM calls, and test agent pipelines from hello world to production test suites. Use context7 skill to study official pytest-asyncio and respx documentation and then build it so no self assumed knowledge. ``` Claude will: 1. Fetch official pytest-asyncio and respx documentation via Context7 2. Ask you clarifying questions (testing patterns, async preferences, coverage goals) 3. Create the complete skill with fixtures, mocking patterns, and templates Your skill appears at `.claude/skills/agent-tdd/`. --- ## Done You now own an `agent-tdd` skill built from official documentation. The rest of this chapter teaches you what it knows—and how to make it better. Every lesson ends with a "Reflect on Your Skill" section where you'll test your skill, identify gaps, and improve it. By the capstone, your skill will generate complete test suites from specifications. **Next: Lesson 1 — TDD Philosophy for Agents**
