The AI-Testing Gap

The Manual Grind

  • Tedious boilerplate for every unit test
  • Struggling to mock complex 3rd party APIs
  • Missing edge cases until users find them
  • Tests feel like a chore that slows you down

The AI Workflow

  • AI writes 80% of mocks and setups
  • Use AI as a brainstorming partner for edge cases
  • Shift from "writing tests" to "verifying tests"
  • Tests provide immediate, automated feedback

Master the Testing Lifecycle

A dedicated deep-dive into AI-assisted software quality.

🧪

AI-Powered TDD

Learn the "Red-Green-Refactor-AI" loop. Write skeleton tests and let AI implement the logic while you verify.

🔍

Edge Case Discovery

AI excels at thinking of what you forgot. Discover off-by-one errors and null pointer exceptions before they hit production.

🎭

Mocking Mastery

Stop struggling with factory bots and manual mocks. Generate realistic test data and service doubles in seconds.

Legacy Code Tests

The hardest part of legacy code is adding tests. Use AI to safely wrap existing code in unit tests without breaking it.

🛡️

Bug-Driven Testing

When a bug is found, use AI to generate a failing test case that perfectly reproduces the issue.

📉

Coverage vs. Value

Avoid coverage theater. Use senior judgment to identify which 20% of tests provide 80% of the safety.

FAQ

AI-generated tests are only as reliable as your review. We teach you how to treat AI as a junior developer who writes the boilerplate while you provide the senior-level verification and architectural oversight.

The mental models are framework-agnostic. Whether you use Vitest, Jest, PHPUnit, Pytest, or Cypress, the principles of AI-assisted TDD remain the same.

Yes. Most devs hate tests because they are tedious. AI handles the tedium—writing setups, mocks, and repetitions—allowing you to focus on the logical "what" and "why".

Ship with zero anxiety.

The testing frameworks you'll learn pay for themselves the first time you catch a production-breaking bug in your dev environment.
