Introduction to Generative AI for Unit Testing

To begin using ChatGPT for unit testing, you need to provide it with a clear prompt. For instance, you might say, 'I'd like your help with creating unit tests for a Python class I have.' This sets the stage for ChatGPT to assist you effectively.

Creating Unit Tests for a Calculator Class

While initial tests are crucial, they often miss edge cases. ChatGPT can help identify these scenarios, such as testing negative numbers, zero operands, large numbers, and invalid inputs. By addressing these edge cases, you can ensure your tests are comprehensive.

Customizing Unit Tests with ChatGPT

When writing unit tests, adhere to best practices: ensure tests apply to your application, avoid redundancy, and focus each test on a single unit of functionality. This clarity will enhance the maintainability and effectiveness of your tests.
