How to test if a file was created?

[bold yarrow]

I'm making a deno library that creates some folders and files, how can i check if it generates then correctly?

try {
  await Deno.open("/path_to_file");
} catch (error) {
  if (error instanceof Deno.errors.NotFound) throw error;
}

Deno.mkdir will throw an error if it fails to create a directory. Including if the directory already exists.

do i just plop this in my test file or what?
