Develop unit tests using GitHub Copilot

In this lab, you will learn how to use GitHub Copilot to generate comprehensive unit tests for your code. Writing tests is crucial for maintaining code quality, but it can be time-consuming. GitHub Copilot can help you generate thorough test cases quickly, including edge cases you might not have considered.

You will learn how to:

  • Use the Chat view and Agent to create a new test class.
  • Use the Chat view and Agent mode to create unit tests.

This lab takes approximately 25-35 minutes to complete.

Before you start

To complete the lab, you need:

  • A GitHub user account with access to GitHub Copilot.
  • Basic understanding of unit testing concepts.
  • Familiarity with a testing framework (e.g., Jest, pytest, JUnit).
  • A web browser with access to the internet.
