I know this is a year old, but I found a way to use multiple parameters with the latest version of Moq at least:  

    mock.Setup(x =&gt; x.Method(It.IsAny&lt;int&gt;(), It.IsAny&lt;int&gt;()))
        .Returns&lt;int, int&gt;((a, b) =&gt; a &lt; b);

For single argument methods, the cleanest way would be:

    mock.Setup(foo =&gt; foo.Submit(IsLarge())).Throws&lt;ArgumentException&gt;();
    ...
    public string IsLarge() 
    { 
      return Match&lt;string&gt;.Create(s =&gt; !String.IsNullOrEmpty(s) &amp;&amp; s.Length &gt; 100);
    }

This can&#39;t be applied if the method has several arguments. There is still a &#39;workaround&#39; that could be used, that mimics what you want to achieve:

    /// &lt;summary&gt;
    /// Tests if a moq can send an exception with argument checking
    ///&lt;/summary&gt;
    [TestMethod]
    public void TestException()
    {
        Mock&lt;IMath&gt; mock = new Mock&lt;IMath&gt;();
        mock.Setup(m =&gt; m.AddNumbersBetween(It.IsAny&lt;int&gt;(), It.IsAny&lt;int&gt;()));

        mock.Setup(foo =&gt; foo.AddNumbersBetween(It.IsAny&lt;int&gt;(), It.IsAny&lt;int&gt;()))
            .Callback&lt;int, int&gt;((i, j) =&gt; CheckArgs(i, j));
            
        try
        {
            mock.Object.AddNumbersBetween(1, 2);
        }
        catch (Exception ex)
        {
            // Will not enter
            Console.WriteLine(&quot;Exception raised: {0}&quot;, ex);
        }
        try
        {
            mock.Object.AddNumbersBetween(2, 1);
        }
        catch (Exception ex)
        {
            // Will enter here, exception raised
            Console.WriteLine(&quot;Exception raised: {0}&quot;, ex);
        }
    }

    private bool CheckArgs(int i, int j)
    {
        if( i &gt; j)
            throw new ArgumentException();
        return true;
    }

I have an interface defined as 

    interface IMath
    {
     AddNumbersBetween(int lowerVal, int upperVal);
    }

I can setup a basic Moq for the above as follows:

    Mock&lt;IMath&gt; mock = new Mock&lt;IMath&gt;();    
    mock.Setup(m =&gt; m.AddNumbersBetween(It.IsAny&lt;int&gt;(), It.IsAny&lt;int&gt;()));

call it

    mock.Object.AddNumbersBetween(1,4);

and then verify that it was called

    mock.Verify(m =&gt; m.AddNumbersBetween(1,4), Times.AtleastOnce());

I cant figure out how to setup the method AddNumbersBetween such that if the upperVal is lower than the lowerVal an exception is thrown

    mock.Object.AddNumbersBetween(4,1);//should throw an exception

Essentially looking for something like:

    mock.Setup(foo =&gt; foo.AddNumbersBetween(&quot;arg1 is higher than arg2&quot;)).Throws&lt;ArgumentException&gt;();

Is there any guidance or best practices around who should call `Dispose()` on disposable objects when they have been passed into another object&#39;s methods or constuctor?

Here&#39;s a couple of examples as to what I mean.

IDisposable object is passed into a method (Should it dispose of it once its done?):

    public void DoStuff(IDisposable disposableObj)
    {
        // Do something with disposableObj
        CalculateSomething(disposableObj)

        disposableObj.Dispose();
    }

IDisposable object is passed into a method and a reference is kept (Should it dispose of it when `MyClass` is disposed?):

    public class MyClass : IDisposable
    {
        private IDisposable _disposableObj = null;
    
        public void DoStuff(IDisposable disposableObj)
        {
            _disposableObj = disposableObj;
        }
    
        public void Dispose()
        {
            _disposableObj.Dispose();
        }
    }

I&#39;m currently thinking that in the first example the *caller* of `DoStuff()` should dispose of the object as it probably created the object. But in the second example it feels like `MyClass` should dispose of the object as it keeps a reference to it. The problem with this is that the calling class might not know `MyClass` has kept a reference and therefore might decide to dispose of the object before `MyClass` has finished using it.
Are there any standard rules for this sort of scenario? If there are, do they differ when the disposable object is being passed into a constructor?

Who should call Dispose on IDisposable objects when passed into another object?

We have a unit test with variable that contains a very long string.

Question is how to write this in code, without having problems with line breaks or that the code is difficult to read.

In VB there is a line continue character, is there an equivilant in C#?

Line continue character in C#

To my surprise, I can&#39;t do anything nearly as simple as this, from what I can tell, in the .NET BCL:

    byte[] response = Http.Post
    (
    	url: &quot;http://dork.com/service&quot;,
    	contentType: &quot;application/x-www-form-urlencoded&quot;,
    	contentLength: 32,
    	content: &quot;home=Cosby&amp;favorite+flavor=flies&quot;
    );

This hypothetical code above makes an HTTP POST, with data, and returns the response from a `Post` method on a static class `Http`.

Since we&#39;re left without something this easy, what&#39;s the next best solution?

How do I send an HTTP POST with data AND get the response&#39;s content?

This is likely a a novice question, but google surprisingly did not provide an answer.

I have this rather artificial method

    T HowToCast&lt;T&gt;(T t)
    {
        if (typeof(T) == typeof(string))
        {
            T newT1 = &quot;some text&quot;;
            T newT2 = (string)t;
        }

        return t;
    }

Coming from a C++ background I have expected this to work. However, it fails to compile with &quot;Cannot implicitly convert type &#39;T&#39; to string&quot; and &quot;Cannot convert type &#39;T&#39; to string&quot; for both of the above assignments.

I am either doing something conceptually wrong or just have the wrong syntax. Please help me sort this one out.

Thank you!

Unittest tests order

I have not been able to debug or step through unit test.

Here is my sample test code...


    using System;
    using System.Text;
    using System.Collections.Generic;
    using System.Linq;
    using Microsoft.VisualStudio.TestTools.UnitTesting;

Stepping through and debugging code in Unit tests

I&#39;m investigating which mocking framework to use for my project and have narrowed it down to [JMockit][1] and [Mockito][2]. 

I notice that *Mockito* was voted &quot;[the best mock framework for Java][3]&quot; on Stackoverflow.  
In comparing features on *JMockit*&#39;s &quot;[Mocking Tool Comparision Matrix][4]&quot;  it appears that *JMockit* has multiple different features.

Does anyone have any specific information (not opinions) on what *Mockito* can do which can&#39;t be achieved with *JMockit* and vice versa?

C# unit test, how to test greater than

Setup as so:


    public interface IFoo
    {
        void Fizz();
    }

    [Test]
    public void A()
    {
        var foo = new Mock&lt;IFoo&gt;(MockBehavior.Loose);

        foo.Object.Fizz();

        foo.Verify(x =&gt; x.Fizz());

        // stuff here

        foo.Verify(x =&gt; x.Fizz(), Times.Never()); // currently this fails
    }

Basically I&#39;d like to enter some code at the `// stuff here` to make the `foo.Verify(x =&gt; x.Fizz(), Times.Never())` pass.

And because this probably constitutes moq/unit testing abuse, my justification is so I can do something like this:

    [Test]
    public void Justification()
    {
        var foo = new Mock&lt;IFoo&gt;(MockBehavior.Loose);
        foo.Setup(x =&gt; x.Fizz());

        var objectUnderTest = new ObjectUnderTest(foo.Object);

        objectUnderTest.DoStuffToPushIntoState1(); // this is various lines of code and setup

        foo.Verify(x =&gt; x.Fizz());

        // reset the verification here

        objectUnderTest.DoStuffToPushIntoState2(); // more lines of code

        foo.Verify(x =&gt; x.Fizz(), Times.Never());
    }

Basically, I have a state object where a fair bit of work (both in terms of making various mock objects and other faffing around) is requires to push it into State1. Then I want to test the transition from State1 to State2. Instead of duplicating or abstracting the code I&#39;d prefer to just re-use the State1 test, push it into State2 and perform my Asserts - all of which I can do except the verification calls.



   





Reset mock verification in Moq?

How do I verify a method was called exactly once with Moq?  The `Verify()` vs. `Verifable()` thing is really confusing.

How do I verify a method was called exactly once with Moq?

I have the following method:

```c#
public CustomObect MyMethod()
{
    var lUser = GetCurrentUser();
    if (lUser.HaveAccess)
    {
        //One behavior
    }
    else 
    {
        //Other behavior
    }

    //return CustomObject
}
```

I want to mock `IMyInterface.GetCurrentUser`, so that while calling `MyMethod` I could get to one of the code paths to check it. How to do that with Moq?

I&#39;m doing the following thing:

```c#
var moq = new Mock&lt;IMyInterface&gt;();
moq.Setup(x =&gt; x.GetCurrentUser()).Returns(lUnauthorizedUser);

//act
var lResult = moq.Object.MyMethod();
```

But for some reason `lResult` is always `null`, and when I&#39;m trying to get into `MyMethod` in debug, I&#39;m always skipping to the next statement.

Using Moq to mock only some methods

I was looking at nuget and wanted to import moq when I noticed AutoFixture AutoMoq. I see that AutoFixture is to help write TDD faster but I can&#39;t find any examples of AutoMoq and how it is different then AutoFixture.


Can someone point me to this AutoMoq so I can see what it is doing.

    public void SubmitMessagesToQueue_OneMessage_SubmitSuccessfully()
    {
        var messageServiceClientMock = new Mock&lt;IMessageServiceClient&gt;();
        var queueableMessage = CreateSingleQueueableMessage();
        var message = queueableMessage[0];
        var xml = QueueableMessageAsXml(queueableMessage);
        messageServiceClientMock.Setup(proxy =&gt; proxy.SubmitMessage(xml)).Verifiable();
        //messageServiceClientMock.Setup(proxy =&gt; proxy.SubmitMessage(It.IsAny&lt;XmlElement&gt;())).Verifiable();

        var serviceProxyFactoryStub = new Mock&lt;IMessageServiceClientFactory&gt;();
        serviceProxyFactoryStub.Setup(proxyFactory =&gt; proxyFactory.CreateProxy()).Returns(essageServiceClientMock.Object);
        var loggerStub = new Mock&lt;ILogger&gt;();

        var client = new MessageClient(serviceProxyFactoryStub.Object, loggerStub.Object);
        client.SubmitMessagesToQueue(new List&lt;IMessageRequestDTO&gt; {message});

        //messageServiceClientMock.Verify(proxy =&gt; proxy.SubmitMessage(xml), Times.Once());
        messageServiceClientMock.Verify();
    }

I&#39;m starting using Moq and struggling a bit.
I&#39;m trying to verify that messageServiceClient is receiving the right parameter, which is an XmlElement, but I can&#39;t find any way to make it work. It works only when I don&#39;t check a particular value.

Any ideas?

Partial answer:
I&#39;ve found a way to test that the xml sent to the proxy is correct, but I still don&#39;t think it&#39;s the right way to do it.

    public void SubmitMessagesToQueue_OneMessage_SubmitSuccessfully()
    {
        var messageServiceClientMock = new Mock&lt;IMessageServiceClient&gt;();
        messageServiceClientMock.Setup(proxy =&gt; proxy.SubmitMessage(It.IsAny&lt;XmlElement&gt;())).Verifiable();
        var serviceProxyFactoryStub = new Mock&lt;IMessageServiceClientFactory&gt;();
        serviceProxyFactoryStub.Setup(proxyFactory =&gt; proxyFactory.CreateProxy()).Returns(messageServiceClientMock.Object);
        var loggerStub = new Mock&lt;ILogger&gt;();

        var client = new MessageClient(serviceProxyFactoryStub.Object, loggerStub.Object);
        var message = CreateMessage();
        client.SubmitMessagesToQueue(new List&lt;IMessageRequestDTO&gt; {message});

        messageServiceClientMock.Verify(proxy =&gt; proxy.SubmitMessage(It.Is&lt;XmlElement&gt;(xmlElement =&gt; XMLDeserializer&lt;QueueableMessage&gt;.Deserialize(xmlElement).Messages.Contains(message))), Times.Once());
    }

By the way, how could I extract the expression from the Verify call?
