codeception symfony2 unit test throws a fatal error - symfony

Question

using the classical phpunit style I generate:test with the symfony2 helper.
I can get the service and I can assert it ok.
// tests
public function testGetServiceUrl() {
$ecservice = $this->getModule('Symfony2')->grabServiceFromContainer("ecservice");
$this->assertEquals("https://ecoconnect2.niwa.co.nz/services", $ecservice->getServiceUrl());
$this->assertEquals("xxx", $ecservice->getServiceUrl());
}
However in the second case where the assertion fails I get an exception:
Trying to test get service url (demoTest::testGetServiceUrl) - Failed

This is because the _failed() function in the Framework.php tries to call client-getResponse(). And we don't have a response class instantiated.
public function _failed(\Codeception\TestCase $test, $fail)
{
if (!$this->client->getResponse()) return;
file_put_contents(\Codeception\Configuration::logDir() . basename($test->getFileName()) . '.page.debug.html', $this->client->getResponse()->getContent());
}
In the example blog post here: http://codeception.com/02-12-2013/testing-symfony2.html There are some extra lines - but they do not fix the problem.
Thanks again Andrew

Answer 1

Well, looks like this function expected to get null from getResponse.
if (!$this->client->getResponse()) return;
This line should have blocked the screenshot call if no response is available.
However it didn't. Looks like an issue. Which Symfony version do you use?
