When switch
statements have large sets of multi-line case clauses, the code becomes hard to read and maintain.
For example, the Cognitive Complexity is going to be particularly high.
In such scenarios, it’s better to refactor the switch to only have single-line case clauses.
When all the case clauses of a switch statement are single-line, the readability of the code is not affected. Moreover,
switch statements with single-line case clauses can easily be converted into switch expressions, which are
more concise for assignment and avoid the need for break statements.
Exceptions
This rule ignores:
-
switch statements over Enum arguments
- fall-through cases
-
return, break and throw statements in case clauses
