💻 Code Samples

[This is an ad from the curator of this newsletter]

Hello, Rubyists!

If you love coding but sometimes find writing tests to be a chore, I have something for you. My upcoming workshop (happening on Friday, 31 October from 16:00 UTC) focuses on using AI to help you generate reliable test cases.

However, this isn't just about relying on AI to do everything for you, it's about understanding the process. We'll explore which aspects of testing can be safely and effectively delegated to an LLM (large language model) and which parts you should continue to handle yourself.

In other words, it's about finding the right balance. You'll learn how to let AI manage the repetitive or standardized testing tasks, allowing you to concentrate on the interesting and fun aspects of your code with confidence. If this sounds appealing to you, come join the workshop!
