Python: create temporary files and directories in unittest - Adam Johnson

Sometimes, tests need temporary files or directories. You can do this in Python’s unittest with the standard library tempfile module. Let’s look at some recipes to do so within individual tests and setUp().

      This. We kinda stumbled on this pattern, and use it to great effect. Simplified code:

      @pytest.fixture
def tmpfiles():
    with NamedTemporaryFile(suffix=".html") as f:
        yield f

# or for paths, which are more suitable for certain tests
# touch them so they exist
@pytest.fixture
def othertmppaths() -> list[Path]:
    f1 = Path("...")
    f1.touch()
    f2 = Path("...")
    f2.touch()

    yield [f1, f2]
    # you could delete them here if needed
    f1.unlink()

def test_foo(othertmppaths list[Path]):
    result = upload_resource(othertmppaths[0]) 
    assert result.status == 200

      The context manager one will properly clean up all files.
