I need to mock any DbCommand calls to the specific sproc. I tried mocking

for the code below but I doesn't work. How can I achieve it?

I'm attempting to test an app that creates an instance of the struct System.Windows.Media.Color.

The color is loaded fine in the actual app, but when testing, I get the error: System.InvalidProgramException: Common Language Runtime detected an invalid program.

This happens on the line where the color is created using Color.FromArgb()..

So I thought perhaps I need to mock the struct and static method. This is what I tried:


but when I run this, I get this error: Telerik.JustMock.MockException: Implementation of method Equals in value types must not throw for mocked instances.

Is there something additional I need to do to mock this struct?

Here is my attempt to mock the interface (I actually want to return a value, but throw just to make it easier to identify):

var cache = Mock.Create<ICache>();

_cacheFactoryMock.Arrange(m => m.Application).Returns(cache);

cache.Arrange(m => m.GetOrAdd(Arg.AnyString, Arg.IsAny<Func<Dictionary<string, string>>>, Arg.IsAny<DateTime>(), Arg.IsAny<TimeSpan>(), null)).Throws(new DivideByZeroException());

Here is the invocation:
 
Here is the method signature of FindLdapUserEmailsInGroup:

The pertinent part of the cachefactory interface:

The pertinent part of ICache:


I'm not sure where I am going wrong.  I have tried several permutations of the dependencies object (using null, default etc), and I'm not sure what could be wrong with the Func<Dictionary<string,string>> arg but nothing I have done so far is getting the arrange to take effect.  Any guidance is appreciated.

I'm trying to test the following, and the class under test's internals are visible to the test class:



With these unit tests



 I'm using VS2010, JetBrains ReSharper 7.0.1, and JetBrains dotCover2.2.  

TestFirstPriceGen() always picks up the mocking and works correctly, whether running it alone, or as part of the UT harness (via Run All Tests or Cover All Tests) - all assertions pass.

However, that doesn't apply for TestRollOneDie() - no matter how I call it (via running the UT directly, or Run/Cover All Tests), it fails the Mock.Assert call, saying:
"Expected PriceSeries.RollOneDie(Int32) call on the mock should be once, but it was called 0 time(s)."

Without that Mock.Assert call, it ignores the mock and calls the original implementation of RollOneDie(), and thus fails 5 out of 6 times.

What am I doing wrong?

I've found an issue between Just Mock Lite when running unit tests that consistently fail, but only under Release build (presumably because of optimized code) and X64 builds with the XUnit test framework. I can't comment on whether this issue occurs under other test frameworks or not, but it definitely goes away under x86 and Debug builds. I have no idea why this happens. Cheers. Here's a sample: -


Here's the test failure message: -

Can't figure out a strategy to test the pattern following:

The problem is to avoid AnotherCall from being called from within VoidCall to isolate VoidCall's implemenation. You can't use IFoo because neither implementation can be called, but the DoNothing doesn't seem to have any effect on avoiding AnotherCall even if you do a foo.AnotherCall(). Also the CallOriginal seems valueless, since without it the method gets called anyway. I don't see the value of it without parameters to VoidCall (but I couldn't even get that to work). As a matter of fact nothing seems any different than not mocking Foo at all. What am I missing in the definition of these Arrange functions.

[TestClass]

    public class FooTest

    {

        [TestMethod]

        public void SimpleExampleWithDoNothing()

        {

            // Arrange

            var foo = Mock.Create<Foo>();

 

            Mock.Arrange(() => foo.VoidCall()).CallOriginal();

            Mock.Arrange(() => foo.AnotherCall()).DoNothing();

 

            // Act

            foo.VoidCall();

 

            // Assert

            Mock.Assert(foo);

        }

    }

 

    public interface IFoo

    {

        void VoidCall();

 

        void AnotherCall();

    }

 

    public class Foo : IFoo

    {

        public void VoidCall()

        {

            AnotherCall();

        }

 

        public void AnotherCall()

        {

            throw new InvalidOperationException();

        }

    }

Hi. 
Is there any option to use MockingContainer to mock properties (not just the ctor)? 
Thanks

Hi..
I use the JustMock first time. I have no idea to test the method below.
Anybody could tell me how to do it.
Thanks.

Hi. I've been looking for any examples (if it's possible) of using JustMock to Unit Test legacy ASP.Net applications. So basically, loading a page and then perhaps some interaction with the page to test the code behind.

Something along the lines of this using TypeMock and Ivonna 

So far I haven't really been able to find anything. Anyone know if it is possible, and any examples?

Many Thanks

Hi Telerik,
In JustMock documents (Entity Framework Mocking) you use :

IList<Dinner> FakeDinners()

And then :

Mock.Arrange(() => nerdDinners.Dinners).ReturnsCollection(FakeDinners());
to mock a DbSet. The problem is where I use " DbContext.DbSet<Dinner>.Find(2) " which gets from context or database the entity with primary key equal to 2.
But in my test where I pass the FakeDinners() ,it doesn't work and return null. Looks like it doesn't know primary key in 
FakeDinners() as it is list. So what is solution?
