Please add a test:

You can do something similar to:

commitizen/tests/test_conf.py

Lines 217 to 224 in 796a160

	class TestTomlConfig:
	def test_init_empty_config_content(self, tmpdir):
	path = tmpdir.mkdir("commitizen").join(".cz.toml")
	toml_config = config.TomlConfig(data="", path=path)
	toml_config.init_empty_config_content()
	with open(path, encoding="utf-8") as toml_file:
	assert toml_file.read() == "[tool.commitizen]\n"

@woile I added test to cz.toml support and extend some other tests about config files. Can you take a look?
