Does the library support this now?

Looking at the source code in Click for isolated_filesystem(): https://github.com/pallets/click/blob/9da166957f5848b641231d485467f6140bca2bc0/src/click/testing.py#L450-L468

python @contextlib.contextmanager def isolated_filesystem( self, temp_dir: t.Optional[t.Union[str, os.PathLike]] = None ) -> t.Iterator[str]: """A context manager that creates a temporary directory and changes the current working directory to it. This isolates tests that affect the contents of the CWD to prevent them from interfering with each other. :param temp_dir: Create the temporary directory under this directory. If given, the created directory is not removed when exiting. .. versionchanged:: 8.0 Added the ``temp_dir`` parameter. """ cwd = os.getcwd() t = tempfile.mkdtemp(dir=temp_dir) os.chdir(t) How about if I pass in that optional temp_dir as a temp directory created using the pytest-xdist aware pytest mechanisms: https://docs.pytest.org/en/6.2.x/tmpdir.html

Tests are still failing in the job that calculates coverage.

That fixed it. My hunch is that Click's runner.isolated_filesystem() mechanism doesn't play well with pytest-xdist.

Still couldn't replicate on my laptop. On a hunch, I'm going to add @pytest.mark.serial to every test that uses runner.isolated_filesystem().

It happens in CI but not on my laptop. I think I need to run the tests on my laptop like this: https://github.com/simonw/datasette/blob/121e10c29c5b412fddf0326939f1fe46c3ad9d4a/.github/workflows/test.yml#L27-L30

One possible treatment:

```html

{% if query.sql and allow_execute_sql %} View and edit SQL {% endif %} Copy and share link

```
