Introduction In this blog post, I want to share my approach to testing functions involving randomness in Go. Recently, I was asked how I would test a specific function that calculates possible directions for an object to move. Initially, I didn’t come up with a good idea. Here, I’ll discuss how I’d solve this problem in a real-world application with a detailed explanation. The Function in Question The function calculates all possible directions that an object can move (up, down, left, right) without violating boundaries.

There are many practices and tactics that tackle testing. Today, I’ll share with you how I write tests for my projects. Please notice that you may find it useful when starting a new project or an independent part of existing applications. You may find it difficult to apply in an already existing application. It’s not impossible but it may be challenging.
