🔥 refactor(custom.py): remove unused code and class 'CustomComponent_old' to improve code cleanliness and maintainability
🔧 fix(test_custom_component.py): fix formatting issues in test_custom_component.py for better readability ✨ feat(test_custom_component.py): add import statements for 'patch' and 'MagicMock' to enable mocking in tests 🔬 test(test_custom_component.py): add test for the 'get_function' method of the Component class with valid code and function_entrypoint_name 🔬 test(test_custom_component.py): add test for the 'parse_assign' method of the CodeParser class 🔬 test(test_custom_component.py): add test for the 'get_code_tree' method of the Component class when given incorrect syntax 🔬 test(test_custom_component.py): add test for the '_class_template_validation' method of the CustomComponent class when the code is None 🔬 test(test_custom_component.py): add test for the 'get_function_entrypoint_args' method of the CustomComponent class 🔬 test(test_custom_component.py): add test for the 'get_function_entrypoint_return_type' method of the CustomComponent class 🔬 test(test_custom_component.py): add test for the 'get_main_class_name' method of the CustomComponent class when there is no main class 🔥 refactor(test_custom_component.py): remove commented out code and unused fixtures to improve code readability and maintainability 🔧 refactor(tests): remove commented out test cases and unused imports ✨ feat(tests): add new test case for list_flows method when there are no flows in the database ✨ feat(tests): add new test case for build_config method when code is not provided ✨ feat(tests): add new test case for list_flows method when there are multiple queries to the database
