Isolate.Verify.WasCalledWithExactArguments

0 votes
Hello,

I'm not sure what to make of this method. Since I get an error that the object passed in has to be a mocked object or specified in WhenCalled() routine, I'm not sure how to make use of this. Basically, I want to ensure that under the scenes, a method was called with the following parameters:

//managerMock is my mocked object
managerMock.AddProperty("FirstName");
managerMock.AddProperty("LastName");
managerMock.AddProperty("ZipCode");

I want to verify that my code validates that all three were added as the result of a method call. How can I do this using WasCalledWithExactArguments?

Thanks.

Hi,

Due to a limitation, Isolator cannot verify against objects that were not faked (created using Fake.Instance(), or were set with a fake behavior using WhenCalled()) - is managerMock such an object? You can simply create it as a fake with the CallOriginal behavior to work around this.

Doron,

In this example, managerMock is a mock I created through Isolate.Fake, and I don't know how to use WasCalledWithExactArguments to verify that a method within the type managerMock is mocking has been called with an exact argument...

So you can't verify strings because they aren't actual mocked objects? I'm just trying to figure out the usefulness of this method.

THanks.

Hi Brian,

You can use AAA API to check that the three strings were called: 
Isolate.WasCalledWithExactArguments(() => managerMock.AddProperty("LastName");
...

MockManager should be either created using Isolate.Fake.Instance, you can use Members.CallOriginal if you need the actual method code to be called or you need to set some expectation on the verified method: 
// Set Expectation - not necessary IgnoreCall
Isolate.WhenCalled(managerMock.AddProperty("")).IgnoreCall();

// Do Something
...

// Assert Call Was Made
Isolate.WasCalledWithExactArguments(() => managerMock.AddProperty("LastName")


The error message does not relate to the parameter unless you have another method call inside the verify block - which we currently do not support: 
// Not supported -- using another call inside the verify block 
Isolate.WasCalledWithExactArguments(() => managerMock.AddProperty(SomeClass.GetSpecialNameString())
