Why is this an issue?
Having all branches in a switch 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 switch/if chain at all.
Noncompliant code example
if (b == 0) // Noncompliant
{
DoTheThing();
}
else
{
DoTheThing();
}
int b = a > 12 ? 4 : 4; // Noncompliant
switch (i) // Noncompliant
{
case 1:
DoSomething();
break;
case 2:
DoSomething();
break;
case 3:
DoSomething();
break;
default:
DoSomething();
}
Exceptions
This rule does not apply to if chains without else-s, or to switch-es without default
clauses.
if (b == 0) //no issue, this could have been done on purpose to make the code more readable
{
DoSomething();
}
else if (b == 1)
{
DoSomething();
}
