HTML Code coverage showing comments as uncovered lines of code

Please refer to stackoverflow.com post:

I've got a class defined as follows:

class User implements UserInterface, \Serializable
{
    ...
        /**
     * Serialize user object and return as a string.
     *
     * @return string
     */
    public function serialize()
    {
        return serialize(array(
            'id' => $this->id,
            'username' => $this->username
        ));
    }

    /**
     * Deserialize from the given $data string.
     *
     * @param string $data
     *
     * @return mixed|void
     */
    public function unserialize($data)
    {
        $data = unserialize($data);
        $this->id = $data['id'];
        $this->username = $data['username'];
        return $this;
    }
    ...
}

When I run my unit tests, they pass 100%, but when looking at my code coverage report, I see the following:

Basically the line where I have @return mixed|void is marked as uncovered code, and it's affecting the code coverage statistics.

The only way to make the error go away, is by either removing either UserInterface, or \Serializable from the implements clause, so this seems to be a problem where a class implements multiple interfaces. When I do this, my class is covered 100%, but with the defect, it is marked as 89.06% covered?

I am using

• PHP Version 5.3.8
• XDebug version v2.2.0-dev
• PHPUnit 3.6.11 by Sebastian Bergmann.

Seems to be an issue in the tokenizer. Definitely a bug and not in any way expected. Thanks for the reproduce :)

Pleasure is all mine, do let me know if you want the full offending class to help fix.

A self-contained, minimal, reproducing test case would be very helpful. Thanks in advance.

He @josefvanniekerk,

i can't repoduce this

<?php

require __DIR__ . '/User.php';

class fooTest extends PHPUnit_Framework_TestCase {

    public function testFoo() {
        $x = new User();
        $x = unserialize(serialize($x));
    }

}

as a test and the class taken as show in the example doesn't work out. I used 5.3.current and xdebug 2.2 so maybe that fixed it?
