I wpuld like to suggest you adding tests for:
- Path() works as expected. Meaning you fi d the tempfile in the expected folder
- Path work even with not empty folder
- failure + error message if Path doesn't exist (unless you plan to create the folder if missing)
- failure + error message validation if tempfile cannot be created (permission, or server has no more space)
- existing files in existing Path folder are still present after Cleanup
- multiple options works: Mode+Path+Pattern+Content

Path() works as expected.
This is in the subtest uses custom path of file is deleted after test. Using a subtest with a custom path was necessary for testing file deletion, so I decided not to create a redundant test for Path. I'll update the name of the deletion test to make it clearer.

Testing there is no error is good, but testing it returns a file not found would be better.

I might have used
| path *string | |
| path string |
Checking path is not-empty would be enough, no?

An empty path is meaningful, as it tells os.CreateTemp to use "the default directory for temporary files, as returned by TempDir." I forgot to document that behavior. I'll leave the pointer there, fix the doc comment on Path, and rename Path to Dir to match the argument in os.CreateTemp.

Oh indeed. That's right. I faced this once. Then I forgot
