Utilizing ExUnit for Streamlined Temporary Directories in Tests

In the realm of testing with Elixir's ExUnit, there's a neat feature provided for handling temporary directories that's often overlooked. Rather than using the standard `System.tmp_dir!/0`, ExUnit offers a tagging option `:tmp_dir` that can be applied to tests. When used, it automatically supplies a temporary directory that's uniquely named based on the module and test names through the test metadata. This ensures safe concurrent running of tests without the risk of overwriting files across different tests. For comprehensive details on the usage, the ExUnit documentation on 'Tmp Dir' is the go-to reference.
