Having all branches in a case or if chain with the same implementation is an error. Either a copy-paste error was made
and something different should be executed, or there shouldn't be a case/if chain at all.
if b == 0 # Noncompliant
doOneMoreThing()
else
doOneMoreThing()
end
b = a > 12 ? 4 : 4; # Noncompliant
case i # Noncompliant
when 1
doSomething()
when 2
doSomething()
when 3
doSomething()
else
doSomething()
end
This rule does not apply to if chains or case-es without else-s.
if b == 0 # no issue, this could have been done on purpose to make the code more readable doSomething() elsif b == 1 doSomething() end
