SetupAllProperties() doesn't work.

[Tobias Wilker]

Hello,

I have a interface IContext which has some properties like IFacade. I have done the following:

Mock<IContext> context = new Mock<IContext>();

context.SetupAllProperties();

After that there is no property set. What is the problem here?

We use the version 4.0.10818.0

Regards.

There is no problem there. It's the designed behavior. 

As mentioned in the quickstart https://code.google.com/p/moq/wiki/QuickStart:

"Setup a property so that it will automatically start tracking its value (also known as Stub):"

And the following bullet:

"Stub all properties on a mock (not available on Silverlight):

mock.SetupAllProperties();

What were yoiu expecting it to be set to?

SetAllProperties() just prepares the properties to be able to be set to a value, and then read back.

I.e. if you do not do SetAllProperties(), when you do this:

context.Object.MyProperty = "wahtever";

when you try to read it, you will still get null, as the Get is not prepared.

If you use:

context.SetupProperty(c => c.MyProperty); //or SetAllProperties

c.Object.MyProperty = "whatever";

now

when you call the property, it'll return "wahtever".

Thx, now I get what this method does. What I am looking for is a method which sets up all properties with mocks, so that in my case IFacade is also mocked and its properties also and so on.

Is there such a method?

Yes, there is. Just do this on the mock:

mock.DefaultValue = DefaultValue.Mock;

This setups the mock so that all properties that don't have an explicit value set return a mocked instance themselves.
Note that you don't need (or better, must not use) mock.SetupAllProperties() then.

Hope that helps.

Thx, this is exactly what I was looking for.
