`toggle_dir.py` is a simple Python script that toggles between two specific directory structures: `src/` and `tests/`. It checks the current working directory and, if it is within a `src/` directory, it switches to the corresponding `tests/` directory and vice versa. The typical command: cd `toggle_dir.py`

        test_dir = base_dir.replace("src", "tests")
        return test_dir
    elif "tests" in base_dir.split(os.sep):

        return src_dir
    else:

        return None
