Testing code with unpredictable or random output
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.
