I use XDebug 2.2.3 together with PHP_CodeCoverage 1.2.12 and PHPUnit 3.7.24 to generate code coverage reports for my code tested by PHPUnit.

My code includes some switch case statements right at the end of methods, so I process a value and depending on it different values get returned right in the switch case:

<pre><code>public function someMethod() {
$value = $this->doSomething();

switch($value) {
case 1:
return true;
case 2:
return false;
case 3:
throw new Exception('Error.');
}
} // This line is marked as "not executed" in the code coverage report</code></pre>

As you can see, there is no case where the switch would be left and PHP would proceed executing the code of the method - instead, in every case the switch is left with a return statement or throwing an Exception.
I don't use a default statement here because I know what the possible return values are. These are also tested by my Unit Tests.
BTW: This bug also works for if conditions using a return statement as I read in Stack Overflow, but I didn't test that.

This is not really a bug in XDebug as the last line (marked in the code) with only the closing curly brace is actually never run - but the question is if this should be like that:
A curly brace (or any other bracket) is not a piece of code to execute - instead, it's a way of structuring the code so the interpreter understands what to do. A curly brace can not even ever be "executed".

My request: Ignore lines with only a brace from code coverage analysis.
