How to exclude files / code blocks from code coverage with Netbeans / PHPStorm / PHPUnit integration

If you are trying to achieve 100% code coverage but have one or more lines that you cannot test, you can surround them with special annotations. They will be ignored in the code coverage report.

if (($result = file_get_contents($url)) === false) {
    // @codeCoverageIgnoreStart
    $this->handleError($url);
    // @codeCoverageIgnoreEnd
}

Edit: I have found that Xdebug often considers the closing brace to be executable. :( If that happens, move the end tag below it.
