Laravel eloquent model reset booted property during unit tests - unit-testing

I have a boot method on a class that extends from Eloquent's base model class. I want to run some unit tests and I need it to fire on each test. Unfortunately, the class ID index is persisting for the Illuminate\Database\Eloquent\Model::$booted property which is set in the constructor that I extend from - so it only works for the first test. I've tried adjusting a few phpunit's flags - I tried process isolation - nothing seems to work.
Is there a way I can reset this property so each test can fire my boot method?
Illuminate\Database\Eloquent\Model.php
public function __construct(array $attributes = array())
{
if ( ! isset(static::$booted[get_class($this)])) <-- Keeps persisting
{
static::$booted[get_class($this)] = true;
static::boot();
}
...
}
app\models\Foo.php
class Foo extends Model {
...
protected static function boot() { <-- first test to execute wins, all other calls get skipped
...
}
...
}

ahh - just a tad more research and the answer is revealed!
My question is basically a duplicate of this question Laravel 4 Model Events don't work with PHPUnit, which references this thread on github for the solution

Unit testing not using correct mocking class

I am using Rhino.Mocks and Structure map to help unit test my code. I have several tests that pass when they are ran by themselves, but when ran as a group fail to pass. The setup code for these unit tests is:
[TestInitialize()]
public void Setup()
{
ObjectFactory.Initialize(x =>
{
x.For(IManager)().Use(Handler)();
});
}
In my tests, I stub out this interface and call the method.
[TestMethod]
public void AreMultiple_Test()
{
var mackIManager = MockRepository.GenerateMock<IManager>();
mackIManager.Stub(u => u.GetTwoUserName(Arg<int>.Is.Anything)).Return(null);
ObjectFactory.Inject(typeof(IManager), mackIManager);
StepAdditionalActionBase actionBase = new StepAdditionalActionBase();
bool areMultiple = actionBase.AreMultiple(new WorkOrder { Id = "123" });
Assert.IsFalse(areMultiple);
}
Test Method 2
[TestMethod]
public void AreMultiple_Test()
{
var mackIManager = MockRepository.GenerateMock<IManager>();
mackIManager.Stub(u => u.GetTwoUserName(Arg<int>.Is.Anything)).Return("123");
ObjectFactory.Inject(typeof(IManager), mackIManager);
StepAdditionalActionBase actionBase = new StepAdditionalActionBase();
bool areMultiple = actionBase.AreMultiple(new WorkOrder { Id = "123" });
Assert.IsTrue(areMultiple);
}
This is unit testing the following code.
public bool AreMultiple(WorkOrder workOrder)
{
string secondUser = _handler.GetTwoUserName(_workflowManager.GetNumberForProject(workOrder.Id));
if (String.IsNullOrEmpty(secondUser ))
{
return false;
}
return true;
}
When I run them by themselves, they work fine. When I run them together, the first passes and the second fails. When I debug the second one, I find that that the return value in the Stubbed method is still coming back as null. How do I get this to use the new Stubbed method.
UPDATE.
I am using StructureMap as my container. From what I have been able to find, the following code is what is used to dispose of the container I got it from this link. When I added this, the test still fail when ran together, but pass when ran individually.
[TestCleanup()]
public void TestCLeanup()
{
ObjectFactory.Container.Dispose();
}
The tests work one by one but fails if run all together. The problem should be in the common part which is being shared across the tests making them dependent from each other. In this particular case that is static ObjectFactory which is nothing else but a Service Locator (anti-pattern).
In the tests, you mock the IManager interface and register it in the ObjectFactory:
ObjectFactory.Inject(typeof(IManager), mackIManager);
Then the SUT uses the ObjectFactory service locator to resolve and use the mocked interface (_handler field):
string secondUser = _handler.GetTwoUserName(...)
I suspect the first test registers the _handler and never clean it up properly, so that the same instance appears in the second test. You should reset the ObjectFactory between tests following the Register Resolve Release pattern.
Another (preferable) option is to refactor your SUT to receive the IManager handler dependency explicitly via constructor. That would simplify both SUT and tests moving the ObjectFactory configuration to the Composition Root.

Why isn't my EventAggregator Subscription Handling This Event?

I have an Autofac DI Container defined as follows:
public class Bootstrapper
{
public IContainer BootStrap()
{
var builder = new ContainerBuilder();
builder.RegisterType<ItemViewModel>().AsSelf();
builder.RegisterType<EventAggregator>()
.As<IEventAggregator>()
.SingleInstance();
}
}
I have a Unit Test defined to test whether a deletion removes the deleted item from the collection:
[Fact]
public void Should_remove_item_from_collection_when_item_is_deleted()
{
const int deletedId = 42;
// adds three items to the collection
_openItemEditViewEvent.Publish(deletedId);
_openItemEditViewEvent.Publish(8);
_openItemEditViewEvent.Publish(9);
// I've tried this:
_eventAggregatorMock.Object.GetEvent<ItemDeletedEvent>().Publish(42);
// and alternatively, this (not at the same time):
_itemDeletedEventMock.Object.Publish(42);
Assert.Equal(2,_vm.ItemEditViewModels.Count); // always fails
Assert.False(_vm.ItemEditViewModels
.Select(vm => vm.Item.Id).Contains(42), "Wrong item deleted");
}
The constructor of the Unit Test initializes and assigns the EventAggregator to the view model:
_eventAggregatorMock = new Mock<IEventAggregator>();
_itemDeletedEventMock = new Mock<ItemDeletedEvent>();
_eventAggregatorMock.Setup(ea => ea.GetEvent<ItemDeletedEvent>())
.Returns(_itemDeletedEventMock.Object);
_vm = new ItemViewModel(_eventAggregatorMock.Object, */ ... /*);
In my actual view model, I Subscribe to the event:
public ItemViewModel(IEventAggregator ea, /* ... */)
{
_eventAggregator.GetEvent<ItemDeletedEvent>()
.Subscribe(OnItemDeleted, true);
}
And we never hit a breakpoint here:
public void OnItemDeleted()
{
// never happens
}
For the life of me, I can't figure out what I'm doing wrong - I'm overlooking something... do I have to Setup the event's Publish event in the Mock? Should I be using a real ItemDeletedEvent instance instead of a Mock? Any help would be greatly appreciated.
=> Hi Scott,
there are 2 ViewModel-scenarios you want to test when using an EventAggregator:
You want to test that your ViewModel is publishing an event
You want to test that your ViewModel does something when an event was published. So the ViewModel has to subscribe to that Event to do something
(Note: The following lines are true for PRISM's EventAggregator, which is the one you're using I guess. For other EventAggregators it could be different)
For the first scenario, you have to create a mock for the event. Then you can verify on that mock-instance that the Publish-method of the Event has been called.
For the second scenario, which is the scenario you have in your question, you have to use the real event in your test. Why?
When you call the Publish-method on a event-mock, that Publish method won't call the subscribers to that Event, as there's no logic behind the Subscribe-method. For sure you could setup both methods and implement that publish/subscribe-logic in your mock. But there's no reason to do so, just use the real Event
When you use the real event, the Publish-method will call all the subscribers. And this is exactly What you need in your test.
It should look like this:
_itemDeletedEvent = new ItemDeletedEvent();
_eventAggregatorMock.Setup(ea => ea.GetEvent<ItemDeletedEvent>())
.Returns(_itemDeletedEvent);
Now your ViewModel will get this itemDeletedEvent-instance from the EventAggregator. In your test you call the Publish-method on this itemDeletedEvent-instance and it will work.

Grails Unit Test Service MissingProperty 'log'

I want to run a unit test for a service. The method I want to test includes a some log.debug() statements. While the log property is injected at runtime, it does not seem to be injected in tests, so it throws groovy.lang.MissingPropertyException: No such property: log for class:
This is my unit test class:
#TestFor(ServiceUnderTest)
#Mock([ServiceUnderTest])
class ServiceUnderTestTests {
def test() {
def mock = [ mockedProp: [...] ] as ServiceUnderTest
def info = mock.doOperation()
assert ....
}
}
I've also tried adding MockUtils.mockLogging(ServiceUnderTest) but with no success.
How can I get the log property properly injected in my service class while in unit tests?
You do not have to have the test class annotated with #Mock([ServiceUnderTest]). #TestFor(ServiceUnderTest) detects its a service class and does all the mocking automatically. It also adds a service property to the test class that can be accessed in all the test methods and mocks the log property accordingly.
I think the problem why neither mocking nor explicit log mocking with MockUtils.mockLogging(ServiceUnderTest) does work in your case is the as coercion you are using in your test method code:
def mock = [ mockedProp: [...] ] as ServiceUnderTest
Groovy internally uses java.lang.reflect.Proxy to create a proxy descendant class from ServiceUnderTest. The proxy class does not see changes done to the ServiceUnderTest meta class like the added log property.
I would solve this issue by using a per-object meta class. You can mock the property getter (or setter) by altering the metaClass of the service object. Be aware that meta-class changes are rolled back by Grails in-between execution of test methods:
service.metaClass.mockedProp = {-> ... }

Issue testing Laravel Controller with Mockery | trying to get property of non-object

I'm very new to testing controllers and I'm running into a problem with a method(). I believe I'm either missing something in my test or my Controller / Repository is designed incorrectly.
The application I'm writing is basically one of those secure "one time" tools. Where you create a note, the system provides you with a URL, once that url is retrieved the note is deleted. I actually have the application written but I am going back to write tests for practice (I know that's backwards).
My Controller:
use OneTimeNote\Repositories\NoteRepositoryInterface as Note;
class NoteController extends \Controller {
protected $note;
public function __construct(Note $note)
{
$this->note = $note;
}
public function getNote($url_id, $key)
{
$note = $this->note->find($url_id, $key);
if (!$note) {
return \Response::json(array('message' => 'Note not found'), 404);
}
$this->note->delete($note->id);
return \Response::json($note);
}
...
I've injected my Note interface in to my controller and all is well.
My Test
use \Mockery as M;
class OneTimeNoteTest extends TestCase {
public function setUp()
{
parent::setUp();
$this->mock = $this->mock('OneTimeNote\Repositories\EloquentNoteRepository');
}
public function mock($class)
{
$mock = M::mock($class);
$this->app->instance($class, $mock);
return $mock;
}
public function testShouldReturnNoteObj()
{
// Should Return Note
$this->mock->shouldReceive('find')->once()->andReturn('test');
$note = $this->call('GET', '/note/1234567890abcdefg/1234567890abcdefg');
$this->assertEquals('test', $note->getContent());
}
}
...
The error I'm getting
1) OneTimeNoteTest::testShouldReturnNoteObj
ErrorException: Trying to get property of non-object
/Users/andrew/laravel/app/OneTimeNote/Controllers/NoteController.php:24
Line 24 is in reference to this line found in my controller:
$this->note->delete($note->id);
Basically my abstracted repository method delete() obviously can't find $note->id because it really doesn't exist in the testing environment. Should I create a Note within the test and try to actually deleting it? Or would that be something that should be a model test? As you can see I need help, thanks!
----- Update -----
I tried to stub the repository to return a Note object as Dave Marshall mentioned in his answer, however I'm now receiving another error.
1) OneTimeNoteTest::testShouldReturnNoteObj
BadMethodCallException: Method Mockery_0_OneTimeNote_Repositories_EloquentNoteRepository::delete() does not exist on this mock object
I do have a delete() method in my repository and I know it's working when I test my route in the browser.
public function delete($id)
{
Note::find($id)->delete();
}
You are stubbing the note repository to return a string, PHP is then trying to retrieve the id attribute of a string, hence the error.
You should stub the repository to return a Note object, something like:
$this->mock->shouldReceive('find')->once()->andReturn(new Note());
Building upon Dave's answer, I was able to figure out what my problem is. I wasn't mocking the delete() method. I didn't understand the need to mock each individual method in my controller that would be called.
I just added this line:
$mock->shouldReceive('delete')->once()->andReturnNull();
Since my delete method is just deleting the note after it is found, I went ahead and mocked it but set it to return null.

Unit test custom doctrine repository

I have a custom entity repository. For example, it looks like this:
namespace Foo\Repository;
use Doctrine\ORM\EntityRepository;
class Article extends EntityRepository
{
public function findRecent($limit)
{
$qb = $this->createQueryBuilder('a');
$qb->andWhere('a.publishDate IS NOT NULL')
->orderBy('a.publishDate', 'DESC')
->setMaxResults($limit);
return $qb->getQuery()->getResult();
}
}
I want to test in this case:
There is an ORDER BY in "recent"
There is a limit
The entity must have a publish date
I do not want to validate the SQL output of the query builder, since Doctrine can change the SQL between different versions. That will break my unit test. Therefore, my idea was this:
Create a mock of my repository
Create a mock of the query builder
Make sure $this->createQueryBuilder('a') returns the mocked query builder
Test for method calls on the query builder
In code:
namespace FooTest\Repository;
use PHPUnit_Framework_TestCase as TestCase;
class ArticleRepositoryTest extends TestCase
{
protected $qb;
protected $repository;
public function setUp()
{
$this->qb = $this->getMockBuilder('Doctrine\ORM\QueryBuilder')
->disableOriginalConstructor()
->getMock();
$this->repository = $this->getMockBuilder('Foo\Repository\Article')
->disableOriginalConstructor()
->getMock();
$this->repository->expects($this->once())
->method('createQueryBuilder')
->with($this->equalTo('a'))
->will($this->returnValue($this->qb));
}
public function testFindRecentLimitsToGivenLimit()
{
$limit = '1';
$this->qb->expects($this->any())
->method('setMaxResults')
->with($this->equalTo($limit));
$this->repository->findRecent($limit);
}
public function testFindRecentOrdersByPublishDate()
{
$this->qb->expects($this->any())
->method('andWhere')
->with($this->equalTo('a.publishDate'), $this->equalTo('DESC'));
$this->repository->findRecent(1);
}
}
This findRecent() call however never calls createQueryBuilder internally. PhpUnit points out:
FooTest\Repository\ArticleRepositoryTest::testFindRecentLimitsToGivenLimit
Expectation failed for method name is equal to when invoked 1 time(s).
Method was expected to be called 1 times, actually called 0 times.
I think I did something wrong in creating the repository mock. How can I make sure this approach works? Or if there is a better alternative, what is that?
It looks to me like you are mocking the Repository you are trying to test, so findRecent() is indeed mocked and will return null.
You should be able to use the real repository instance.
The solution I found to testing subclassed repositories is to add a call to setMethodsExcept() when building the mock.
So you would modify your code within setUp() above like so:
$this->repository = $this->getMockBuilder('Foo\Repository\Article')
->disableOriginalConstructor()
->setMethodsExcept([
// Insert any overridden/implemented functions here, in your case:
'findRecent',
])
->getMock();
