How to test service function without connecting on database - symfony

Question

I'm turning again on you guys, because I spend my fair share of hours on this "task" and I still can't figure out how to test my service method, without my function connection on database (I have to mock repository functions)
This is my service function
public function getInfo($history, $name)
{
$requestRepository = $this->em->getRepository(Request::class);
if ($history) {
$requests = [];
foreach ($requestRepository->getRequestsByName($name) as $request) {
$requests[] = $requestRepository->transform($request);
}
return $requests;
} else {
$request = $requestRepository->getCompletedRequestByName($name);
if (!is_null($request)) {
return $requestRepository->transform($request);
} else {
return null;
}
}
}
And this is my test
public function testGetInfo()
{
/* This returns errors, because it tries to connect to DATABASE, but I don't wan't that, that's why I figure out I need to mock this
$requestManager = new RequestManager($this->entityManager);
$test = $requestManager->getInfo('histroy', 'antrax.com');
*/
$requestManager = $this->getMockBuilder(RequestManager::class)->disableOriginalConstructor()->setMethods(['getInfo'])
->getMock();
// And rest of this are just my FAILED attempts to figure out, how to test my methods
$queryBuilder = $this->getMockBuilder(RequestRepository::class)->disableOriginalConstructor()
->setMethods(['getInfo'])->getMock();
$test = $queryBuilder->method('getInfo')->willReturnSelf();
$queryBuilder->method('getInfo')->willReturnCallback(function ($field, $value) use ($queryBuilder, $test){
if ($field == 'newStatus') {
$this->assertSame('EXPIRED', $value);
}
return $queryBuilder;
});
}
Can some one please help me how to write a test for my method getInfo so it will have 100% cover. If you need any additional informations, please let me know and I will provide. Thank you!

This is an answer to my problem
public function testGetInfo()
{
$mockEntity = $this->mockEntityManager;
$name = 'antrax.com';
$requestMock = new RequestEntity();
$transformedRequest = [
'id' => 1
];
$requestRepo = $this->getMockBuilder(RequestRepository::class)->disableOriginalConstructor()
->setMethods(['getRequestsByName', 'transform', 'getCompletedRequestByName'])->getMock();
$requestRepo->method('getRequestsByName')->willReturnCallback(function ($passedName) use ($name, $requestMock) {
$this->assertSame($name, $passedName);
return [$requestMock, $requestMock];
});
$requestRepo->method('transform')->willReturnCallback(function ($request) use ($requestMock, $transformedRequest) {
$this->assertSame($requestMock, $request);
return $transformedRequest;
});
$i = 0;
$requestRepo->method('getCompletedRequestByName')->willReturnCallback(function ($passedName) use ($name, $requestMock, &$i) {
$this->assertSame($name, $passedName);
if ($i == 0) {
$i+=1;
return null;
} else {
return $requestMock;
}
});
$mockEntity->method('getRepository')->willReturnCallback(function ($requestClass) use ($requestRepo) {
$this->assertSame(RequestEntity::class, $requestClass);
return $requestRepo;
});
$requestManager = new RequestManager($mockEntity);
$this->assertSame([$transformedRequest, $transformedRequest], $requestManager->getInfo(true, $name));
$this->assertNull($requestManager->getInfo(false, $name));
$this->assertSame($transformedRequest, $requestManager->getInfo(false, $name));
}
