DomDocument::loadHTML() error during phpunit test execution

I am currently trying to write some unit test against my zend framework controller. When I run the following code I receive this error:

public function testListActionShouldContainListTable()
    {

        $this->loginToSystem();

        $uri = $this->_uriBase . 'campaign/list';
        $_SERVER["REQUEST_URI"] = $uri;

        $this->dispatch('/campaign/list');
        $this->assertController('campaign');
        $this->assertAction('list');
        $this->assertQueryCount('#list',1);
    }


CampaignControllerTests::testListActionShouldContainListTable
DOMDocument::loadHTML(): ID alrt already defined in Entity, line: 36

This occurs using any of the assertQuery and assertQueryContains methods. I have searched around but am not really finding a good answer to why it won't allow me to fi开发者_Python百科nd this html node or how to get around this error.

Thanks in advance for any help!

Make sure the document is valid. You have duplicate IDs in your HMTL document.

The HTML being generated by the dispatch is bad (it looks like it has two ids being assigned to a single tag). This is not an error of your test (it's working fine), it's an error in your html output generated by the test...
