EF 6 Alpha 3 Mocking

[James Legan]

I grabbed Alpha 3 this morning from NuGet and I seem to be unable to mock EF6 the way I would normally mock OpenAccess. When I try a simple:

var test = Mock.Create<DemoEntities>();

I get a TypeLoadException:

Method 'CallValidateEntity' on type 'DemoEntitiesProxy+53c69f86fe444525a693c487adc77799' from assembly 'Telerik.JustMock.Dynamic, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is overriding a method that is not visible from that assembly.

Any thoughts?

Hi James,

I managed to reproduce the issue. It seems that it is a bug in JustMock, which prevents us from being able to mock internal virtual methods with proxy. However, our developers are currently investigating the matter for its cause.

As a workaround, I could suggest you to use the Elevated Automocking feature of our product. With it, I was able to write the following test and it passed:

// Arrange
var mockContainer = new MockingContainer<Model1Container>();

var fakeEntity = new Entity1();

mockContainer.Arrange<Entity1>(x => x.Id).IgnoreInstance().Returns(555);

// Act
var actual = fakeEntity.Id;

// Assert
Assert.AreEqual(555, actual);

I hope this helps. I will keep you nottified when we would be able to provide you with a solution, containing the bug fix.

P.S. For reporting such bug in our product, I have granted you some Telerik points.

 

Kind regards,
