DuplicateBranches
Both branches contain identical code

The problem

Branching constructs (if statements, conditional expressions) should contain difference code in the two branches. Repeating identical code in both branches is usually a bug.

For example:

condition ? same : same

if (condition) {
  same();
} else {
  same();
}

this usually indicates a typo where one of the branches was supposed to contain different logic:

condition ? something : somethingElse

if (condition) {
  doSomething();
} else {
  doSomethingElse();
}
