Unit testing guzzle http promises callbacks - php

Question

I have the following code in a class:
private function makeRequest(DetailedPayload $detailedPayload, $request): void
{
$this->httpClient
->sendAsync($request)
->then(
function (ResponseInterface $response) use ($detailedPayload) {
$this->handleServerResponse($detailedPayload, $response);
},
function (RequestException $exception) use ($detailedPayload) {
$this->logRequestException($detailedPayload, $exception);
}
);
}
An now my handler functions looks like so:
private function handleServerResponse(DetailedPayload $detailedPayload, ResponseInterface $response): void
{
if (200 === $response->getStatusCode()) {
try {
$this->queueDataPublisher->publish($detailedPayload);
} catch (FailedToPublishQueueDataException $exception) {
$this->logPublisherException($detailedPayload, $response);
}
} else {
$this->logNonOkResponse($detailedPayload, $response);
}
}
Now I want to test my class which has the signature:
public function __construct(Client $httpClient, LoggerInterface $logger, QueueDataPublisher $queueDataPublisher)
I can mock all the logger and the publisher class and also can follow the instruction to mock the http request as mentioned on the guzzle documentation found here: http://docs.guzzlephp.org/en/stable/testing.html
My test looks as below:
/**
* #test
*
* #throws \Exception
*/
public function willMakeHttpRequestToServer()
{
$client = new Client(
[
'handler' => HandlerStack::create(
new MockHandler(
[
new Response(200)
]
)
)
]
);
$logger = $this->prophesize(LoggerInterface::class);
$queueDataPublisher = $this->prophesize(QueueDataPublisher::class);
$transportClient = new TransportClient($client, $logger->reveal(), $queueDataPublisher->reveal());
$detailedPayload = (new DetailedPayload())
->setStepId('test_step_id')
->setStageId('test_stage_id')
->setProtocolId('test_protocol_id')
->setPayload('test_payload');
$queueDataPublisher
->publish($detailedPayload)
->shouldBeCalled();
$transportClient->sendPayload($detailedPayload);
}
But I can never get this test to green. Has andbody tried something like this to test the async request.
Any idea on how I can approach to test this implementation.
The test requrns the response telling the expectation to call of a function on publisher failed as so:
No calls have been made that match:
