Incorrect parentheses in method definition

Reports method definitions with the incorrect parentheses style. Parentheses are expected in method definitions with parameters, opposite to method definitions without parameters.

Example:

# Bad practice
def example_method(); end
def example_method_with_parameters param1, param2; end

Quick-fixes are available to remove the parentheses or add them respectively. After the quick-fixes are applied, the result looks like this:

# Good practice
def example_method; end
def example_method_with_parameters(param1, param2); end
