PHPUnit testing xcache

Question

So as it's know xcache is not working under CLI but still want to test some functionality what is related partially to xcache under symfony2. Having the following snippet

//this is a working snippet 
$key = 'likes';
$cache = $this->getXcacheCache();
if ($cache->contains($key)) {
    $likes = $cache->fetch($key);
} elseif ($profile = $this->getProfile()) {
    $likes = $this->getProfile()->getProperty('likes');
    $cache->save($key, $likes, 3600);
}

Is there a way to unit test xcache if contains a specific key and run other tests based on this condition?
