Testing CliRunner with isolated_filesystem fails

• I added a very descriptive title here.

Example Code

from typer.testing import CliRunner

 @pytest.mark.acceptance
 class TestInitCli:
     def setup_method(self) -> None:
         self._runner = CliRunner()

     def _run_cli_with_config(self, config: dict) -> dict:
        with tempfile.NamedTemporaryFile(mode="w", suffix=".yml", delete=False) as config_file:
            yaml.dump(config, config_file)
            config_file_path = config_file.name

        with self._runner.isolated_filesystem():
            result = self._runner.invoke(app, ["--config", str(config_file_path)])

        return {
            "exit_code": result.exit_code,
            "errors": result.exception,
        }

Description

I have an acceptance test that executes a CLI application built with typer. Previously, in the test, I executed the application inside an isolated filesystem, as it creates some folders and files that I want to be temporary and don't want to be created inside the project.

I've updated the dependencies, including typer, and now the method I was using, _runner.isolated_filesystem(), no longer exists. I've tried using the context manager method isolation(), but it doesn't have the same effect.

Is a similar method available with the new version?

Hi @dimanu-py! I'm afraid we have decided to discontinue support for isolated_filesystem. This functionality came from Click and was undocumented in Typer's docs. It has been removed since the vendoring of Click in #1774. See also Tiangolo's comment here.

Thanks for the info! I guess I'll have to do my own context manager to imitate the behavior
