Symfony ignore mock in test service - unit-testing

Question

I'm trying to test a service using phpunit. When i mock a function in my StatServiceTest, my service ignore the mock i did.
with an example will be more clear :
my service.yml
my_service:
class: '%my_service.class%'
parent: parent_service
arguments:
- '#service.repository.commutation'
- '#service.repository.stat'
- '#service.repository.switchboard'
- '%sunrise_host%'
my service : StatService.php
class StatService extends AbstractService
{
protected $commutationRepository;
protected $statRepository;
protected $switchboardRepository;
protected $sunrise_host;
public function __construct(CommutationRepository $commutationRepository, StatRepository $statRepository, SwitchboardRepository $switchboardRepository, $sunrise_host)
{
$this->commutationRepository = $commutationRepository;
$this->statRepository = $statRepository;
$this->switchboardRepository = $switchboardRepository;
$this->sunrise_host = $sunrise_host;
}
public function getNightsWithSunService($id, $start, $end)
{
$switchboard = $this->switchboardRepository->getById($id);
$parameters = array(
'begin' => (int) $start,
'end' => (int) $end,
'lat' => (float) $switchboard->getElement()->getCoordinate()->getLat(),
'lng' => (float) $switchboard->getElement()->getCoordinate()->getLng(),
'timezone' => $switchboard->getElement()->getCoordinate()->getTimezone(),
);
$buzz = new Buzz();
$result = $buzz->post(
$this->sunrise_host.'/nights',
array(
'Content-Type' => 'application/json',
),
json_encode($parameters)
);
return json_decode($result->getContent(), true);
}
}
and finally my StatServiceTest.php
class StatServiceTest extends WebTestCase
{
public function testGetNightsWithSunService()
{
$dic = $this->_client->getKernel()->getContainer();
$sunriseHost = $dic->getParameter('sunrise_host');
$id = 426;
$start = 1538400421;
$end = 1538569621;
$mapNights = $this->getNights();
$mockStatService = $this->getMockBuilder("StatService")
->disableOriginalConstructor()
->getMock();
$mockStatService
->expects($this->any())
->method('getNightsWithSunService')
->withConsecutive(array($id, $start, $end))
->willReturnOnConsecutiveCalls($mapNights)
;
$statService = new StatService($mockCommutationRepository,
$mockStatRepository, $mockSwitchboardRepository, $sunriseHost);
$result = $statService->getNightsWithSunService($id, $start, $end);
$nights = array(
array(
'start' => 1538414415,
'end' => 1538458643,
),
array(
'start' => 1538500702,
'end' => 1538545117,
),
);
$this->assertTrue($this->arrays_are_similar($nights, $result));
}
public function getNights()
{
$nights = array(
array(
'start' => 1538414415,
'end' => 1538458643,
),
array(
'start' => 1538500702,
'end' => 1538545117,
),
);
return $nights;
}
public function arrays_are_similar($a, $b)
{
// we know that the indexes, but maybe not values, match.
// compare the values between the two arrays
foreach ($a as $k => $v) {
if ($v !== $b[$k]) {
return false;
}
}
// we have identical indexes, and no unequal values
return true;
}
}
the error is :
testGetNightsWithSunService
Buzz\Exception\RequestException:
file_get_contents(http://localhost:4244/nights): failed to open
stream: Connection refused
i instantiate my service and i inject in it repositories that i mocked, i just put the part of code that concerns the problem.
What i did wrong ? please any advice will be helpful

Answer 1

The solution i founded is to do another service => toolsService with a function callback for the buzz part, and then we can inject this service and will be more easy to mock it.
I hope that will help you
