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:

  • Generate unit tests with GitHub Copilot
  • Create test cases for different scenarios
  • Implement test fixtures and setup code
  • Write assertions and validation logic
  • Cover edge cases and error conditions
  • Use testing best practices with AI assistance

This lab takes approximately 45-60 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.

Complete the exercise on Microsoft Learn

In this exercise, you'll learn to develop unit tests using GitHub Copilot.

Note: This exercise demonstrates how AI can help you write comprehensive tests more efficiently.

The exercise consists of the following activities:
