Having all branches in a match 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 match/if chain at all.

Noncompliant Code Example

if (b == 0) { // Noncompliant
  doSomething
} else {
  doSomething
}

i match { // Noncompliant
  case 1 => doSomething
  case 2 => doSomething
  case 3 => doSomething
  case _ => doSomething
}

Exceptions

This rule does not apply to if chains without else-s, or to match-es without case _ alternatives.

if (b == 0) {
  doSomething
} else if (b == 1) {
  doSomething
}
