How to Test the Interaction of several Clients
If you need to simulate an interaction between different clients (think of a chat for instance), create several clients:
1 2 3 4 5 6 7 8 9 10
// ...
$harry = static::createClient();
$sally = static::createClient();
$harry->request('POST', '/say/sally/Hello');
$sally->request('GET', '/messages');
$this->assertEquals(Response::HTTP_CREATED, $harry->getResponse()->getStatusCode());
$this->assertRegExp('/Hello/', $sally->getResponse()->getContent());2.4
Support for HTTP status code constants was introduced in Symfony 2.4.
This works except when your code maintains a global state or if it depends on a third-party library that has some kind of global state. In such a case, you can insulate your clients:
1 2 3 4 5 6 7 8 9 10 11 12 13
// ...
$harry = static::createClient();
$sally = static::createClient();
$harry->insulate();
$sally->insulate();
$harry->request('POST', '/say/sally/Hello');
$sally->request('GET', '/messages');
$this->assertEquals(Response::HTTP_CREATED, $harry->getResponse()->getStatusCode());
$this->assertRegExp('/Hello/', $sally->getResponse()->getContent());Insulated clients transparently execute their requests in a dedicated and clean PHP process, thus avoiding any side-effects.
Tip
As an insulated client is slower, you can keep one client in the main process, and insulate the other ones.
