Unit Testing ASP.NET? ASP.NET unit testing has never been this easy.

Typemock is launching a new product for ASP.NET developers – the ASP.NET Bundle - and for the launch will be giving out FREE licenses to bloggers and their readers.

The ASP.NET Bundle is the ultimate ASP.NET unit testing solution, and offers both Typemock Isolator, a unit test tool and Ivonna, the Isolator add-on for ASP.NET unit testing, for a bargain price.

Typemock Isolator is a leading .NET unit testing tool (C# and VB.NET) for many ‘hard to test’ technologies such as SharePoint, ASP.NET, MVC, WCF, WPF, Silverlight and more. Note that for unit testing Silverlight there is an open source Isolator add-on called SilverUnit.

The first 60 bloggers who will blog this text in their blog and tell us about it, will get a Free Isolator ASP.NET Bundle license (Typemock Isolator + Ivonna). If you post this in an ASP.NET dedicated blog, you'll get a license automatically (even if more than 60 submit) during the first week of this announcement.

Also 8 bloggers will get an additional 2 licenses (each) to give away to their readers / friends.

Go ahead, click the following link for more information on how to get your free license.

*End*

Once you post this in your site, just drop them a line at asp@typemock.com with your name and the post URL to get your free license.

Hurry up – this offer is limited to the first 60 bloggers, or to ASP.NET dedicated bloggers who will post this in the first week.

Make sure to follow their Blog, Site or Twitter for updates on this event.

This major version adds static method support and non-public method faking to the AAA API. Check out the release notes.

I don’t like the reflective approach to testing private methods.

With the new additions to the AAA API, testing this class:

public class MyClass
{
    public string Public()
    {
        return this.Private();
    }

    private string Private()
    {
        throw new NotImplementedException();
    }
}

can be done like this:

[TestMethod]
[Isolated]
public void PrivateTest()
{
    MyClass fake = Isolate.Fake.Instance<MyClass>();

    Isolate.WhenCalled(() => fake.Public()).CallOriginal();

    Isolate.NonPublic.WhenCalled(fake, "Private").WillReturn("FAKE");

    string fakePublic = fake.Public();

    Assert.AreEqual("FAKE", fakePublic);

    Isolate.Verify.WasCalledWithExactArguments(() => fake.Public());

    Isolate.Verify.NonPublic.WasCalled(fake, "Private");
}

I would like it better if it was like this:

[TestMethod]
[Isolated]
public void PrivateTest()
{
    MyClass fake = Isolate.Fake.Instance<MyClass>();

    MyClass_Accessor fakeAccessor = MyClass_Accessor.AttachShadow(fake);

    Isolate.WhenCalled(() => fakeAccessor.Private()).WillReturn("FAKE");

    Isolate.WhenCalled(() => fake.Public()).CallOriginal();

    string fakePublic = fake.Public();

    Assert.AreEqual("FAKE", fakePublic);

    Isolate.Verify.WasCalledWithExactArguments(() => fake.Public());

    Isolate.Verify.WasCalledWithExactArguments(() => fakeAccessor.Private());
}

Looks almost the same but there aren’t any method names in the test code.

They were able to do it for Natural Mocks. I’m sure they will eventually do it for AAA.

Some time ago I was asked if it was possible to fake output parameters with Typemock Isolator.

It’s actually very easy using any of the APIs.

Given this class:

public class MyClass
{
    public bool MyMethod(string input, out int output1, out double output2)
    {
        throw new NotImplementedException();
    }
}

Using the new AAA API, it's as clean as:

[TestMethod]
[Isolated]
public void TestMethodIsolated()
{
    MyClass target = Isolate.Fake.Instance<MyClass>();

    string input = "test value";
    int expectedOutput1 = 1;
    double expectedOutput2 = 2;

    Isolate.WhenCalled(() => target.MyMethod(input, out expectedOutput1, out expectedOutput2)).WillReturn(true);

    int output1;
    double output2;
    bool result = target.MyMethod(input, out output1, out output2);

    Assert.IsTrue(result);
    Assert.AreEqual<int>(expectedOutput1, output1);
    Assert.AreEqual<double>(expectedOutput2, output2);
}

Using Natural Mocks, it's as easy as:

[TestMethod]
[VerifyMocks]
public void TestMethodNatural()
{
    MyClass target = RecorderManager.CreateMockedObject<MyClass>();

    string input = "test value";
    int expectedOutput1 = 1;
    double expectedOutput2 = 2;

    using (RecordExpectations recorder = RecorderManager.StartRecording())
    {
        recorder.ExpectAndReturn(target.MyMethod(input, out expectedOutput1, out expectedOutput2), true);
    }

    int output1;
    double output2;
    bool result = target.MyMethod(input, out output1, out output2);

    Assert.IsTrue(result);
    Assert.AreEqual<int>(expectedOutput1, output1);
    Assert.AreEqual<double>(expectedOutput2, output2);
}

It's also possible using Reflective Mocks:

[TestMethod]
[VerifyMocks]
public void TestMethodReflective()
{
    MockObject<MyClass> targetMock = MockManager.MockObject<MyClass>();

    string input = "test value";
    int expectedOutput1 = 1;
    double expectedOutput2 = 2;

    targetMock.ExpectAndReturn(
        "MyMethod",
        new DynamicReturnValue(delegate(object[] parameters, object context)
            {
                parameters[1] = expectedOutput1;
                parameters[2] = expectedOutput2;
                return true;
            }));

    int output1;
    double output2;
    bool result = targetMock.Object.MyMethod(input, out output1, out output2);

    Assert.IsTrue(result);
    Assert.AreEqual<int>(expectedOutput1, output1);
    Assert.AreEqual<double>(expectedOutput2, output2);
}

All you have to do is choose which one you like most.

Typemock has released an alpha version of its newest product: Typemock Racer.

Typemock Racer is the tool that uses dynamic and static analysis to find deadlocks in .NET code that had been previously announced by Roy Osherove.

Typemock has released version 5.0 of its unit testing tool: Isolator. Check out the release notes.

This new version comes with a new API: Arrange Act Assert:

• Isolator AAA API - The Basics
• Isolator AAA: Creating Fakes

I’ll have to say that I liked Isolator better over Isolate.

Also new in this version is the inclusion of the help file in the installation package.

Today Typemock released version 4.3 of Typemock Isolator. Download it from here.

What’s new?

• Support for Ivonna. For those of you who develop ASP.Net applications, Ivonna is a great tool, built on top of Isolator’s platform, to simplify writing tests for ASP.NET.
• Typemock.Integration.Packs namespace APIs added to support license management through Isolator, the way Ivonna does.
• As announced when it was released, version 4.2 was the last version of Isolator to support .NET 1.1. Version 4.3 only supports the 2.0 runtime and its Visual Studio counterparts: VS2005 and VS2008.
• For 64 bit machines, now there’s a single installer. (don’t forget to uninstall both previous 32 and 64 installers prior to installing 4.3.)
• RecorderManager.GetMockOf(instanceRef) and MockManager.GetMockOf(instanceRef). To retrieve the mock controller object based on a reference to the instance. (more...).

Bug fixes:

• Fixes to DLINQ support. LINQ Queries with data tables now work better, for example with GroupBy.
• Static constructors in Natural Mocks are now invoked correctly.
• A bug that caused an exception to be thrown when mocking interfaces ("Method XX in type IMyInterface has no matching overload that returns TypeMock.Mock+a) was fixed.
• A bug that caused an exception to be thrown when the mocked object was overriding Equals was fixed.
• A bug that caused failure in mocking explicit interface with the same name was fixed.
• A bug occurring im multithreading scenarios in VerifyWithWait was fixed.
• A bug that causes NullReferenceException to be thrown when using Auto Deploy was fixed.
