What are node paths?

The report contain headings and a checklist where the items are paths to the class/function/parameter where the error is present. Node paths are double colon :: separated names and can be any of the following format:

• Class path: [file_name]::[class_name]
• Function path: [file_name]::[function_name]
• Function parameter path: [file_name]::[function_name]::[parameter_name]
• Method path: [file_name]::[class_name]::[function_name]
• Method parameter path: [file_name]::[class_name]::[function_name]::[parameter_name]

Following functions require tests [doctest/unittest/pytest]:

• graphs/breadth_first_search.py::Graph::print_graph
• graphs/breadth_first_search.py::Graph::add_edge
• graphs/breadth_first_search.py::Graph::bfs

Following functions require return type hints:

NOTE: If the function returns None then provide the type hint as def function() -> None

• graphs/breadth_first_search.py::Graph::__init__
