I am new and this feels like a stupid question so please just hear me out. I have a project that will work its way through a directory and find any video files in non-video folders and visa versa. I want to put some testing in but I have never done serious testing before. How would I go about it? And wouldn’t testing be impossible since the result could change when I send it to my client or whenever any of the folders I am using for testing change? Or is this just a problem where I have to just deal with it?
