You can use `It.IsAny&lt;T&gt;()` to match any value:

    mockInvoice.Setup(x =&gt; x.IsInFinancialYear(It.IsAny&lt;FinancialYearLookup&gt;())).Returns(true);

See the [Matching Arguments][1] section of the quick start.


  [1]: https://github.com/Moq/moq4/wiki/Quickstart#matching-arguments

Try using `It.IsAny&lt;FinancialYearLookup&gt;()` to accept any argument:

    mockInvoice.Setup(x =&gt; x.IsInFinancialYear(It.IsAny&lt;FinancialYearLookup&gt;())).Returns(true);

You can try the following:

https://7pass.wordpress.com/2014/05/20/moq-setup-and-ignore-all-arguments/

Allows:

    mock
    .SetupIgnoreArgs(x =&gt; x.Method(null, null, null)
    .Return(value);

I am trying to check to see if a string that I am going to use as URL starts with http. The way I am trying to check right now doesn&#39;t seem to be working. Here is my code:

    NSMutableString *temp = [[NSMutableString alloc] initWithString:@&quot;http://&quot;];
    if ([businessWebsite rangeOfString:@&quot;http&quot;].location == NSNotFound){
        NSString *temp2 = [[NSString alloc] init];
        temp2 = businessWebsite;
        [temp appendString:temp2];
        businessWebsite = temp2;
        NSLog(@&quot;Updated BusinessWebsite is: %@&quot;, businessWebsite);
    }
    
    [web setBusinessWebsiteUrl:businessWebsite];
Any ideas? 

How to see if an NSString starts with a certain other string?

Why can&#39;t I do this?

    class A
    {
    public:
        int a, b;
    };

    class B : public A
    {
        B() : A(), a(0), b(0)
        {
        }

    };


How can I initialize base class member variables in derived class constructor?

I have some code in a test using Moq:

    public class Invoice
    {
        ...
    
        public bool IsInFinancialYear(FinancialYearLookup financialYearLookup)
        {
            return InvoiceDate &gt;= financialYearLookup.StartDate &amp;&amp; InvoiceDate &lt;= financialYearLookup.EndDate;
        }
        ...
    }

So in a unit test I&#39;m trying to mock this method and make it return true

    mockInvoice.Setup(x =&gt; x.IsInFinancialYear()).Returns(true);

Is there anyway to write this line so I don&#39;t have to specify the input to `IsInFinancialYear`. ie. So that it doesn&#39;t in the code what the input parameter is it will return true whatever is passed to it?

The following gets a field from a DataTable and converts it to string.  Is there a cleaner way to convert dynamic to string?

    dynamic value = dataTable.Rows[i].Field&lt;dynamic&gt;(columnName);
    value = (value == null) ? null : value.ToString();


C# Best way to convert dynamic to string

While using the `using() {}` (sic) blocks as shown below, and assuming that `cmd1` does not live beyond the scope of the first `using() {}` block, why should the second block throw an exception with the message 

&gt; The SqlParameter is already contained by another SqlParameterCollection

Does it mean that resources and/or handles - including the parameters (`SqlParameterCollection`) - attached to `cmd1` are not released when its destroyed at the end of the block?

    using (var conn = new SqlConnection(&quot;Data Source=.;Initial Catalog=Test;Integrated Security=True&quot;))
    {
        var parameters = new SqlParameter[] { new SqlParameter(&quot;@ProductId&quot;, SqlDbType.Int ) };

        using(var cmd1 = new SqlCommand(&quot;SELECT ProductName FROM Products WHERE ProductId = @ProductId&quot;))
        {
            foreach (var parameter in parameters)
            {
                cmd1.Parameters.Add(parameter);                
            }
            // cmd1.Parameters.Clear(); // uncomment to save your skin!
        }

        using (var cmd2 = new SqlCommand(&quot;SELECT Review FROM ProductReviews WHERE ProductId = @ProductId&quot;))
        {
            foreach (var parameter in parameters)
            {
                cmd2.Parameters.Add(parameter);
            }
        }
    }


**NOTE:** Doing cmd1.Parameters.Clear() just before the last brace of the first **using() {}** block will save you from the exception (and possible embarrassment).

If you need to reproduce you can use the following scripts to create the objects:

    CREATE TABLE Products
    (
        ProductId int IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
        ProductName nvarchar(32) NOT NULL
    )
    GO

    CREATE TABLE ProductReviews
    (
        ReviewId int IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
        ProductId int NOT NULL,
        Review nvarchar(128) NOT NULL
    )
    GO


The SqlParameter is already contained by another SqlParameterCollection - Does using() {} cheat?

I&#39;m using [A Fast CSV Reader][1] to parse some pasted text into a webpage. The Fast CSV reader requires a TextReader object, and all I have is a string. What&#39;s the best way to convert a string into a TextReader object on the fly?

Thanks!

Update-
Sample code- In the original sample, a new StreamReader is looking for a file called &quot;data.csv&quot;. I&#39;m hoping to supply it via TextBox_StartData.Text.

Using this code below doesn&#39;t compile.



            TextReader sr = new StringReader(TextBox_StartData.Text);
            using (CsvReader csv = new CsvReader(new StreamReader(sr), true))
            {
                DetailsView1.DataSource = csv;
                DetailsView1.DataBind();
            }

The `new StreamReader(sr)` tells me it has some invalid arguments. Any ideas?

As an alternate approach, I&#39;ve tried this:

            TextReader sr = new StreamReader(TextBox_StartData.Text);
            using (CsvReader csv = new CsvReader(sr, true))
            {
                DetailsView1.DataSource = csv;
                DetailsView1.DataBind();
            }

but I get an `Illegal characters in path Error.` Here&#39;s a sample of the string from TextBox_StartData.Text:

    Fname\tLname\tEmail\nClaude\tCuriel\tClaude.Curiel@email.com\nAntoinette\tCalixte\tAntoinette.Calixte@email.com\nCathey\tPeden\tCathey.Peden@email.com\n

Any ideas if this the right approach? Thanks again for your help!

In C#, how can I create a TextReader object from a string (without writing to disk)

I was just curious about this: the following code will not compile, because we cannot modify a foreach iteration variable:


            foreach (var item in MyObjectList)
            {
                item = Value;
            }

But the following will compile and run:

            foreach (var item in MyObjectList)
            {
                item.Value = Value;
            }

Why is the first invalid, whereas the second can do the same underneath (I was searching for the correct english expression for this, but I don&#39;t remember it. Under the...? ^^ )

Why can&#39;t we assign a foreach iteration variable, whereas we can completely modify it with an accessor?

I currently have two unrelated MVC3 projects hosted online.

One works fine, the other doesn&#39;t work, giving me the error:

&gt; Multiple types were found that match the controller named &#39;Home&#39;. This
&gt; can happen if the route that services this request
&gt; (&#39;{controller}/{action}/{id}&#39;) does not specify namespaces to search
&gt; for a controller that matches the request. 
&gt;
&gt; If this is the case,
&gt; register this route by calling an overload of the &#39;MapRoute&#39; method
&gt; that takes a &#39;namespaces&#39; parameter.

The way my hoster works is that he gives me FTP access and in that folder I have two other folder, one for each of my applications.

&gt; ftpFolderA2/foo.com
&gt;
&gt; ftpFolderA2/bar.com

foo.com works fine, I publish my application to my local file system then FTP the contents and it works.

When I upload and try to run bar.com, the issue above fires and prevents me from using my site. **All while foo.com still works**.

Is bar.com searching from controllers EVERYWHERE inside of ftpFolderA2 and that&#39;s why it&#39;s finding another `HomeController`? How can I tell it to only look in the Controller folder as it should?

Facts:

 1. Not using areas. These are two COMPLETELY unrelated projects. I place each published project into each respective folder. Nothing fancy.
 2. Each project only has 1 HomeController.

Can someone confirm this is the problem?

Multiple types were found that match the controller named &#39;Home&#39;

I&#39;m developing a Web API, and one of the test I came up with is that, if client makes a GET operation with a Physical Test ID (Physical Test is the resource I&#39;m looking for) and that physical test is not found, the web API should return a 404 status.

Now, I&#39;m using moq framework for my tests and I have the following code:

    [TestMethod]
    public void then_if_physical_test_not_found_return_not_found_status()
    {
        var unitOfWork = new Mock&lt;IUnitOfWork&gt;();
        var repository = new Mock&lt;IRepository&lt;PhysicalTest&gt;&gt;();
        repository.Setup(r =&gt; r.FindById(It.IsAny&lt;int&gt;())).Returns();
        unitOfWork.Setup(m =&gt; m.PhysicalTests).Returns(repository.Object);
        var pt = new PhysicalTestResource(unitOfWork.Object);
        HttpResponseMessage&lt;PhysicalTest&gt; response = pt.GetPhysicalTest(43);
        Assert.AreEqual(HttpStatusCode.NotFound, response.StatusCode)
    }

I need the Returns() method to return a null object, which is going to be what the actual API method would return if the resource is not found.

I tried sending null as a parameter in the Returns() method but had no success.

moq objects Returns method, should return a null object

    protected int parseExpire(CacheContext ctx) throws AttributeDefineException {
    	Method targetMethod = ctx.getTargetMethod();
    	CacheEnable cacheEnable = targetMethod.getAnnotation(CacheEnable.class);
    	ExpireExpr cacheExpire = targetMethod.getAnnotation(ExpireExpr.class);
    	// check for duplicate setting
    	if (cacheEnable.expire() != CacheAttribute.DO_NOT_EXPIRE &amp;&amp; cacheExpire != null) {
    		throw new AttributeDefineException(&quot;expire are defined both in @CacheEnable and @ExpireExpr&quot;);
    	}
    	// expire time defined in @CacheEnable or @ExpireExpr
    	return cacheEnable.expire() != CacheAttribute.DO_NOT_EXPIRE ? cacheEnable.expire() : parseExpireExpr(cacheExpire, ctx.getArgument());
    }

that is the method to test , 

    Method targetMethod = ctx.getTargetMethod();
    CacheEnable cacheEnable = targetMethod.getAnnotation(CacheEnable.class);

I have to mock three CacheContext,Method and CacheEnable.
Is there any idea to make the test case much simpler?

mock or stub for chained call

Is there a way to have a stubbed method return different objects on subsequent invocations? I&#39;d like to do this to test nondeterminate responses from an `ExecutorCompletionService`. i.e. to test that irrespective of the return order of the methods, the outcome remains constant.

The code I&#39;m looking to test looks something like this.

    // Create an completion service so we can group these tasks together
    ExecutorCompletionService&lt;T&gt; completionService =
            new ExecutorCompletionService&lt;T&gt;(service);

    // Add all these tasks to the completion service
    for (Callable&lt;T&gt; t : ts)
        completionService.submit(request);

    // As an when each call finished, add it to the response set.
    for (int i = 0; i &lt; calls.size(); i ++) {
        try {
            T t = completionService.take().get();
            // do some stuff that I want to test
        } catch (...) { }        
    }

Using Mockito with multiple calls to the same method with the same arguments

I am using [mock][1] with Python and was wondering which of those two approaches is better (read: more pythonic). 

**Method one**:  Just create a mock object and use that. The code looks like:

    def test_one (self):
        mock = Mock()
        mock.method.return_value = True 
        self.sut.something(mock) # This should called mock.method and checks the result. 
        self.assertTrue(mock.method.called)

**Method two**:  Use patch to create a mock.  The code looks like:

    @patch(&quot;MyClass&quot;)
    def test_two (self, mock):
        instance = mock.return_value
        instance.method.return_value = True
        self.sut.something(instance) # This should called mock.method and checks the result. 
        self.assertTrue(instance.method.called)

Both methods do the same thing.  I am unsure of the differences. 

Could anyone enlighten me?

Mocking a class: Mock() or patch()?

I&#39;m trying to mock something while testing a Django app using the imaginatively named [Mock testing library][1]. I can&#39;t seem to quite get it to work, I&#39;m trying to do this:

    class Promotion(models.Model):
        foo = models.ForeignKey(FooClass)

What am I doing wrong?

Using mock patch to mock an instance method

I am developing tests for an application. There&#39;s a method that has a `params` array as a parameter. I have set up the method using Moq but when I run the test, the return value of the method is null, which means it is not being mocked.

Here&#39;s a code sample:

    public interface ITicketManager {
        string GetFirstTicketInQueueIfMatches(params string[] ticketsToMatch);
    }

    public class TicketManager : ITicketManager {
        private Queue&lt;string&gt; ticketQueue = new Queue&lt;string&gt;();

        public string GetFirstTicketInQueueIfMatches(params string[] ticketsToMatch) {
            var firstQueuedTicket = ticketQueue.Peek();
            var firstQueuedTicketMatchesAnyOfRequested = ticketsToMatch.Any(t =&gt; t == firstQueuedTicket);

            if(firstQueuedTicketMatchesAnyOfRequested)
                return firstQueuedTicket;

            return null;
        }
    }

The mock code looks like this:

    var mock = new Mock&lt;ITicketManager&gt;();

    mock.Setup(m =&gt; m.GetFirstTicketInQueueIfMatches(It.IsAny&lt;string&gt;()))
        .Returns(p =&gt; { 
	    if(p.Contains(&quot;A&quot;))
                return &quot;A&quot;;
		   
		return null;
    });

Why is it never hitting the mocked method?

Setup Method With Params Array

I&#39;m trying to verify that a method within a mock is called with an expected object parameter.  I&#39;m using Moq, nUnit, and thinking that AutoFixture&#39;s Likeness should get the job done.
Below is a simplified version of what i&#39;m trying to do.  

Is there a way to do this with AutoFixture?  Is there a better way to verify that `Something` is called with the appropriate parameter?

Overriding Equals in the `A` class to compare the property values and changing the `Verify` line to:

    barMock.Verify(m =&gt; m.Something(a));
passes, however I&#39;d rather not override Equals in every class like A in my project. 

    namespace Test
    {
        using Moq;
        using NUnit.Framework;
        using Ploeh.SemanticComparison.Fluent;
    
        public class A
        {
            public int P1 { get; set; }
        }
        public interface IBar
        {
            void Something(A a);
        }
    
        public class Foo
        {
            public A Data { get; private set; }
            public void DoSomethingWith(IBar bar)
            {
                Data = new A { P1 = 1 };
                bar.Something(Data);
            }
        }
    
        [TestFixture]
        public class AutoFixtureTest
        {
            [Test]
            public void TestSample()
            {
                var foo = new Foo();
                var barMock = new Mock&lt;IBar&gt;();
                var a = new A { P1 = 1 };
                var expectedA = a.AsSource().OfLikeness&lt;A&gt;();
    
                foo.DoSomethingWith(barMock.Object);
    
                expectedA.ShouldEqual(foo.Data);   // passes
                barMock.Verify(m =&gt; m.Something(expectedA.Value));  // fails
            }
        }
    }

Using Verify to confirm expected parameter values in Moq mock class

With Moq, is it valid to have more than one Matching Argument?


    It.Is&lt;string&gt;() 


In this example I want the mockMembershipService to return a different ProviderUserKey depending on the User supplied.

    mockMembershipService.Setup(
        x =&gt; x.GetUser(
          It.Is&lt;string&gt;(
            s =&gt; s.Contains(&quot;Joe&quot;)))
       .ProviderUserKey)
    .Returns(&quot;1234abcd&quot;);


    mockMembershipService.Setup(
      x =&gt; x.GetUser(
        It.Is&lt;string&gt;(
          s =&gt; s.Contains(&quot;Tracy&quot;)))
      .ProviderUserKey)
    .Returns(&quot;5678efgh&quot;);

The SetUp defaults to the second statement rather than evaluating each on its own merits.



           


Multiple Moq It.Is&lt;string&gt;() Matching Arguments

I am fairly new to unit testing in C# and learning to use Moq. Below is the class that I am trying to test.

    class MyClass
    {
        SomeClass someClass;
        public MyClass(SomeClass someClass)
        {
            this.someClass = someClass; 	
        }

        public void MyMethod(string method)
        {
            method = &quot;test&quot;
            someClass.DoSomething(method);
        }	
    }

    class Someclass
    {
        public DoSomething(string method)
        {
            // do something...
        }
    }

Below is my TestClass:

    class MyClassTest
    {
        [TestMethod()]
        public void MyMethodTest()
        {
            string action=&quot;test&quot;;
            Mock&lt;SomeClass&gt; mockSomeClass = new Mock&lt;SomeClass&gt;();
            mockSomeClass.SetUp(a =&gt; a.DoSomething(action));
            MyClass myClass = new MyClass(mockSomeClass.Object);
            myClass.MyMethod(action);
            mockSomeClass.Verify(v =&gt; v.DoSomething(It.IsAny&lt;string&gt;()));
        }
    }

I get the following exception:

    Expected invocation on the mock at least once, but was never performed
    No setups configured.
    No invocations performed..

I just want to verify if the method &quot;MyMethod&quot; is being called or not. Am I missing something?
