Reviewer's verdict

A decent 45-minute demo of what the button does. It shows you the workflow for generating simple unit tests with Copilot, which is a real time-saver for boilerplate. Just don't expect it to teach you how to write good tests.

Decision summary

3.2/5 Last verified: August 31, 2026

Best for

Developers who already have Copilot and want a quick tour of its test generation features in VS Code.

Watch for

The example is a 'happy path' scenario; it doesn't cover mocking or complex dependencies.

Who it's for

Developers who already have Copilot and want a quick tour of its test generation features in VS Code.

Who should skip it

Anyone looking for deep test design principles or how to handle complex, stateful codebases.

Pros

  • Quick, hands-on walkthrough of the Copilot Chat interface for testing.
  • The exercise uses a realistic, if simple, scenario (a C# banking app).
  • Shows both generating new tests and fixing/extending existing ones.

Cons

  • The example is a 'happy path' scenario; it doesn't cover mocking or complex dependencies.
  • Feels more like a product demo than a course on test-driven development.
  • The 'Knowledge Check' is trivial and doesn't test real understanding.

The included C# banking app is a good sandbox for this. Copilot spits out boilerplate Arrange-Act-Assert blocks faster than I can type them, which is a genuine productivity gain.

But the core problem remains: Copilot can't read your mind. It generated tests for the happy path because the sample code was simple. I tried pointing it at a gnarlier piece of my own code with a few dependencies, and the suggestions got noisy fast. It's good at scaffolding, but you're still the one responsible for thinking through edge cases, mocking dependencies, and verifying the logic is actually sound. This module shows you where the button is. It doesn't show you how to drive.
