Usually, it doesn't take a lot to get short scripts and functions up and running. However, as your code-base becomes larger and more complex errors will creep in inevitably. It has even been mathematically proven that any code beyond a certain level of complexity includes at least one bug and probably quite more than that.
So long story short, one should always apply appropriate testing strategies to mitigate risk, BUT sometimes this #ThoughtOnProgramming given by Christopher Thompson might help as well 🙃.
