Function git_testtools::scripted_fixture_repo_read_only

pub fn scripted_fixture_repo_read_only(
    script_name: impl AsRef<Path>
) -> Result<PathBuf>

Run the executable at script_name, like make_repo.sh to produce a read-only directory to which the path is returned. Note that it persists and the script at script_name will only be executed once if it ran without error.
