Are design patterns actually a code smell?
Context—Design patterns represent recommended generic solutions to various design problems, whereas code smells are symptoms of design issues that could hinder further maintenance of a software system.
How do I modify SonarQube rules?
You can’t modify an existing rule. A workaround is to write a custom rule. However, you should first seriously consider whether the behavior you want to achieve is really specific to your own environment. If that’s not the case, you can suggest a change to the existing rule by joining the SonarQube google group.
When do you call something a code smell?
Calling something a CodeSmell is not an attack; it’s simply a sign that a closer look is warranted. So while not all of these common characteristics may always indicate that a code smell is present, it is very important that all software engineers be very familiar with the different types of code smells.
What does the smell of too many parameters mean?
Method-level smells: Too many parameters: a long list of parameters is hard to read, and makes calling and testing the function complicated. It may indicate that the purpose of the function is ill-conceived and that the code should be refactored so responsibility is assigned in a more clean-cut way.
Which is an example of a bloater code smell?
Many of the common examples of bloater code smells include: Classes that are entirely too big (Large Class) Methods and functions that are also entirely too big (Long Method) Way too many parameters for a given function (Long Parameter List) Too many primitives and constants that should be encapsulated together in an object (Primitive Obsession)
One way to look at smells is with respect to principles and quality: “Smells are certain structures in the code that indicate violation of fundamental design principles and negatively impact design quality”. Code smells are usually not bugs; they are not technically incorrect and do not prevent the program from functioning.
