Mocking framework integrations for Stashbox that provide automatic mock creation for your services in unit tests.

Moq

You can use the auto mock framework by creating a StashMoq instance wrapped in a using statement, on its disposal it will call Verify() on all the configured expectations.

//begin a test scope
using (var stash = StashMoq.Create())
{
    //configure a mock dependency
    stash.Mock<IDependency>().Setup(m => m.Test()).Returns("test");
    
    //configure the mock again
    //this call will get the same mock back as the first request
    stash.Mock<IDependency>().Setup(m => m.Test2());
    
    //get the tested service filled with auto created mocks (except the configured ones)
    var service = stash.Get<IService>();
    
    //call the tested method, imagine that this will invoke the Test() method of an IDependency
    var result = service.Test();
    
    //check the result
    Assert.Equal("test", result);
    
} //StashMoq will call the Verify() method on all configured expectations on its dispose

You can also set the verifyAll parameter of StashMoq with that it will call the VerifyAll() on the used mock repository. StashMoq.Create(verifyAll: true)

Mock behavior

You can set which mock behavior should be used by the framework by default.

using (var stash = StashMoq.Create(MockBehavior.Strict)) //the default will be strict
{
    //this mock will be strict
    stash.Mock<IDependency>().Setup(m => m.Test()).Returns("test");
    
    //you can also override the default config, this mock will be loose
    stash.Mock<IDependency2>(MockBehavior.Loose).Setup(...);
}

FakeItEasy

You can use the auto mock framework by creating a StashItEasy instance wrapped in a using statement.

//begin a test scope
using (var stash = StashItEasy.Create())
{
    //configure a mock dependency
    var fake = stash.Fake<IDependency>();
    
    //configure the call
    A.CallTo(() => fake.Test()).Returns("test");
    
    //get the tested service filled with auto created fakes (except the configured ones)
    var service = stash.Get<IService>();
    
    //call the tested method, imagine that this will invoke the Test() method of the IDependency
    var result = service.Test();
    
    //check the call
    A.CallTo(() => fake.Test()).MustHaveHappened();
    
    //check the result
    Assert.Equal("test", result);    
}

Options

You can set what fake options should be used by the framework by default.

using (var stash = StashItEasy.Create(x => x.Strict())) //the default will be strict
{
    //this fake will be strict
    stash.Fake<IDependency>();
    
    //you can also override the default config
    stash.Fake<IDependency>(x => x.Implements<IDependency3>());
}

NSubstitute

You can use the auto mock framework by creating a StashSubstitute instance wrapped in a using statement.

//begin a test scope
using (var stash = StashSubstitute.Create())
{
    //configure a mock dependency
    var sub = stash.Sub<IDependency>(); //for multiple interface implementations use the overloads of this method
    sub.Test().Returns("test");
    
    //get the tested service filled with auto created mocks (except the configured ones)
    var service = stash.Get<IService>();
    
    //call the tested method, imagine that this will invoke the Test() method of an IDependency
    var result = service.Test();
    
    //check the call
    sub.Recieved().Test();
    
    //check the result
    Assert.Equal("test", result);   
}

You can also get a partial mock with the stash.Partial<IDependency>() call.

RhinoMocks

You can use the auto mock framework by creating a StashRhino instance wrapped in a using statement, on its disposal it will call VerifyAllExpectations() on all the configured expectations.

//begin a test scope
using (var stash = StashRhino.Create())
{
    //configure a mock dependency
    stash.Mock<IDependency>().Expect(x => x.Test()).Returns("test");
    
    //configure the mock again
    //this call will get the same mock back as the first request
    stash.Mock<IDependency>().Expect(m => m.Test2());
    
    //get the tested service filled with auto created mocks (except the configured ones)
    var service = stash.Get<IService>();
    
    //call the tested method, imagine that this will invoke the Test() method of an IDependency
    var result = service.Test();
    
    //check the result
    Assert.Equal("test", result);   
    
} //StashRhino will call the VerifyAllExpectations() method on all configured expectations on its dispose

Mock types

You can also request different mock types from StashRhino:

using (var stash = StashRhino.Create())
{
    //this will create a dynamic mock
    stash.Mock<IDependency>();
    
    //this will create a strict mock
    stash.Strict<IDependency>();
    
    //this will create a partial mock
    stash.Partial<IDependency>();
}

Rocks

You can use the auto mock framework by creating a StashRocks instance wrapped in a using statement, on its disposal it will call Verify() on all the configured expectations.

//begin a test scope
using (var stash = StashRocks.Create())
{
    //configure a mock dependency
    stash.Mock<IDependency>().Handle(x => x.Test()).Returns("test");
    
    //generate all mock objects and register them into the StashboxContainer
    stash.MakeAll();
    
    //get the tested service filled with auto created mocks (except the configured ones)
    var service = stash.Get<IService>();
    
    //call the tested method, imagine that this will invoke the Test() method of an IDependency
    var result = service.Test();
    
    //check the result
    Assert.Equal("test", result);   

} //StashRocks will call the Verify() method on all configured expectations on its dispose

Further things that each package offers

  • All package allows the service instantiation by a selected constructor with pre-evaluated arguments:
var service = stash.GetWithConstructorArgs<Service>(mockObject1, mockObject2);

//you can also use a placeholder argument where you don't want to set a concrete object
var service = stash.GetWithConstructorArgs<Service>(StashArg.Any<IMock>(), mockObject2);

If you use an argument placeholder with a non-mockable type, the framework will throw a NonMockableTypeException.

  • All package allows the dependency override with pre-evaluated dependencies:
//this will inject the `mockObject1` into the created `Service` everywhere it fits by its type
var service = stash.GetWithParamOverrides<Service>(mockObject1);
You can’t perform that action at this time.
