-/// Generates a test for each file that matches the specified pattern.
-///
-/// The attributed function must have exactly one argument of the type `&Path`.
-/// The `#[test]` attribute must come after the `#[fixture]` argument or `test` will complain
-/// that your function can not have any arguments.
-///
-/// ## Examples
-///
-/// Creates a test for every python file file in the `fixtures` directory.
-///
-/// ```ignore
-/// #[fixture(pattern="fixtures/*.py")]
-/// #[test]
-/// fn my_test(path: &Path) -> std::io::Result<()> {
-///     // ... implement the test
-///     Ok(())
-/// }
-/// ```
-///
-/// ### Excluding Files
-///
-/// You can exclude files by specifying optional `exclude` patterns.
-///
-/// ```ignore
-/// #[fixture(pattern="fixtures/*.py", exclude=["a_*.py"])]
-/// #[test]
-/// fn my_test(path: &Path) -> std::io::Result<()> {
-///     // ... implement the test
-///     Ok(())
-/// }
-/// ```
-///
-/// Creates tests for each python file in the `fixtures` directory except for files matching the `a_*.py` pattern.
