What's inside

  1. 1
    Code Testing for Agentic Dev: Start Here

    A 12-minute orientation to the Code Testing skill path — the five feedback layers that keep Claude Code and Codex honest, and the order to learn them in

    12 min
  2. 2
    Testing Foundations

    Test strategy, the testing trophy, and writing automated tests that actually catch bugs

    18 min
  3. 3
    Static Analysis for Agentic Development

    Wire Ruff, Biome, Pyrefly, ty, Semgrep, and CodeQL as sub-second feedback sources for Claude Code and Codex

    20 min
  4. 4
    Pre-Commit Guardrails for AI Agents

    Wire format, lint, type-check, and test into a layered hook stack that forces Claude Code and Codex to fix before they commit

    20 min
  5. 5
    Coverage & Mutation Testing

    The two-tool feedback loop — coverage shows where tests are missing, mutation shows whether the tests you have actually catch bugs

    22 min
  6. 6
    AI-Driven Test Generation

    From one-shot prompts to feedback-driven loops — drive, supervise, and review the systems that now write your tests

    28 min
  7. 7
    Property-Based & Fuzz Testing

    Move past hand-picked examples — specify invariants, let generators hunt counterexamples, and pair the discipline with agents that propose the properties you missed

Frequently asked questions

What will I learn in this code testing course?
You build five feedback layers that catch bugs in AI-written code: a test strategy with automated tests, static analysis using tools like Ruff, Semgrep, and CodeQL, layered pre-commit hooks, coverage paired with mutation testing, and AI-driven test generation plus property-based and fuzz testing. Every layer is shown applied to Claude Code and Codex output.
Who is this path for?
It is built for software engineers who use AI coding agents like Claude Code and Codex and want guardrails that keep generated code correct. It sits at a practitioner level, so it assumes you already write and run code day to day.
Do I need prior experience or to know how to code?
Yes. This is a practitioner-level path for engineers, not a beginner intro. You should be comfortable writing code, running a test suite, and working at the command line before you start.
How long is the course and is there a certificate?
The path has 7 chapters totaling about 142 minutes, roughly 2.4 hours, including a 12-minute orientation chapter. You earn a certificate of completion when you finish all chapters.
Is this course free?
No, this is a paid path included with an AI Academy subscription. It covers static analysis, coverage, mutation testing, pre-commit hooks, AI test generation, and property-based testing across all 7 chapters.
