I can't get the first condition Everything works fine in IntelliJ. I put in a directory and file on my own computer to test it. Everything works. But for some reason, the tests don't like how I renamed the file. But it accepts the renamed file and writes to it properly. I'm ready to pull my hair out on this one. Any thoughts?
