· Overview

This release mainly focuses on new features for MbUnit.
NHamcrest
NHamcrest is an idiomatic C# port of Hamcrest (java version) made by Graham Hay. It provides a nice fluent syntax for Assert.That. The library is now part of the Gallio bundle.
[Test]
public void Assert_that()
{
Assert.That(1, Is.Anything());

Assert.That(1 + 1, Is.EqualTo(2));
Assert.That("string", Is.EqualTo("string"));
Assert.That(5.0, Is.EqualTo(5.0));

Assert.That(false, Is.False());
Assert.That(true, Is.True());

Assert.That(null, Is.Null());
Assert.That("", Is.NotNull());

Assert.That(5, Is.LessThan(6));
Assert.That(5, Is.GreaterThan(4));

const string aString = "aString";
Assert.That(aString, Is.SameAs(aString));
Assert.That("the cat sat on the mat", Starts.With("the cat"));
Assert.That("the cat sat on the mat", Contains.String("sat on"));
Assert.That("the cat sat on the mat", Ends.With("the mat"));

Assert.That(1, Is.InstanceOf<int>());

Assert.That(() => { throw new ArgumentException(); }, Throws.An<ArgumentException>());
}
Assert.HasAttribute(s)
2 new assertions to check whether a code element is decorated with a specific attribute. Those assertions are particularly powerful when used in combination with the Mirror API.
[DisplayName("Item")]
public class Product
{
public int Id { get; set; }

[Required, StringLength(10)]
public string Name { get; set; }

[Required]
public string Description { get; set; }

[Required, Range(0, 1000)]
public decimal Price { get; set; }
}
[TestFixture]
public class ProductTest
{
[Test]
public void Product_has_DisplayNameAttribute()
{
Assert.HasAttribute<DisplayNameAttribute>(typeof(Product));
}

[Test]
public void Description_has_RequiredAttribute()
{
var property = Mirror.ForType<Product>()["Description"];
Assert.HasAttribute<RequiredAttribute>(property);
}
}
Case insensitive string matching.
Assert.Contains, Assert.DoesNotContain, Assert.StartsWith, and Assert.EndsWith now support case insensitive string matching.
[Test]
public void Assert_contains()
{
string actualValue = "Edgar Allan Poe (January 19, 1809 – October 7, 1849)";
string expectedSubstring = "ALLAN POE";
Assert.Contains(actualValue, expectedSubstring, StringComparison.OrdinalIgnoreCase);
}
Assert.DoesNotExist
Again a new assertion which finally brings some symmetry to Assert.Exists.
[Test]
public void Assert_doesNotExist()
{
var data = new[] { "Athos", "Porthos", "Aramis" };
Assert.DoesNotExist(data, x => x.Contains("gnan"));
}
Multiple [Impersonate] instances
Running tests under another identity is a little-known feature of MbUnit. It is now possible to provide several user credentials at once.
[Test]
[Impersonate(UserName = "Julius", Password = "Ven1V1d1V1c1")]
[Impersonate(UserName = "Brutus", Password = "F**kD4ddy")]
public void Test()
{
var identity = WindowsIdentity.GetCurrent();
TestLog.Write("User = {0}", identity.Name);
}
And many other things...
Such as improvements to contract verifiers, "Seed" property to the random data sources, easier ways to assert over inner exceptions, etc.

Multi-page Reports in Gallio/MbUnit v3.3

While the announcement of a new intermediate release of Gallio/MbUnit is imminent (next week?), we are continuing to focus on the major improvements that will be available in the future versions.

In case you are running Gallio against very large test suites (> 10000 tests), you might be interested by the following new feature. You can experiment it already by installing the latest v3.3 daily build (it's pretty stable already, IMHO)

As you may know, we dropped the XSL-based engine used for the report generation, in favor of high performing VTL templates (based on Castle NVelocity). The generation of the Text/HTML reports (Text, Text-Condensed, Html, Html-Condensed, XHtml, and XHtml-Condensed) is about 3 times faster. But more important, the report writer now supports multi-paging. Say goodbye to the heavy 20Mb reports that take hours to open in the web browser! Gallio is now able to split large reports into several smaller browsable files.



You might configure some parameters from the Gallio Control Panel. It's machine-wide settings that will affect the reports generated by every tool and test runner.

What's next?

Gallio/MbUnit v3.2.2 was released some days ago. And we've got many "thank you" for the resolution of this annoying CS1685 issue (thank you Graham for having fixed it).

Now what can you expect from the incoming releases of Gallio? The path to v3.3 is still long, but we plan to release several intermediate point releases with more fixes, more improvements and a lot of new features. In a random order, here is an overview of those future new nifty features:
  • Major performance improvements: We are in the process of replacing the XSLT-based engine which generates the test reports by a brand new and faster system based on Castle NVelocity. We also would like to do no longer rely on that damn slow .NET Remoting for IPC communications and to use the popular Google's Protobuf format instead. Those major changes should bring dramatic performance improvements while running the tests and formatting the test reports.
  • MbUnitCpp: a port of the MbUnit testing framework to the native unmanaged C++ realm; entirely integrated to the Gallio ecosystem. It’s not feature complete yet, but MbUnitCpp is already fully functional and available as part of the daily v3.3 builds. The wiki documentation is also very detailed already; with a comprehensive tutorial.
  • NHamcrest support: Graham Hay did port recently Hamcrest to C#. Assert.That is going to be extended to support that fluent API.
  • PartCover support: A new adapter for this excellent test coverage tool.
  • New assertions, new contract verifiers, and many other little enhancements (see draft release notes for detailed)
Some of those features are in fact fully or partially available in the v3.3 trunk already. Feel free to test them. Feedback and suggestions are always gratefully received.

And of course, we will continue to closely follow the continuous releases of the 3rd party tools that coexist in the Gallio ecosystem and to update the existing test adapters and plugins accordingly.

MbUnit v3 to support (N)Hamcrest

Recently, Graham Hay did port the well-known Hamcrest library to .NET. The new version of that library was judiciously ;) named NHamcrest. It is also fully integrated to Gallio/MbUnit with Assert.That.

Try it out by downloading the latest v3.3 daily build and give us feedback and suggestions.
[Test]
public void NHamcrestExample()
{
var array = new[] {"red", "green", "blue"};
Assert.That(array, Is.InstanceOf(typeof(string[])));
Assert.That(array, Has.Items(new[] { "green", "red" }));
Assert.That(array, Has.Item<string>(Starts.With("bl")));
}

Testing Custom Data Source Attributes in MbUnit v3.2

In a recent post, I explained how to create a custom data source attribute for MbUnit. But before using it, it's certainly safer to test it. The method described below is the same as the one which is applied in the MbUnit test project itself. It is widely used to verify that the built-in attributes of MbUnit behave as expected. The principle is the following:
  1. Create a nested explicit sample test fixture which consumes the attribute under test. It must be marked as explicit, so that it will not be taken in account by the primary test runner.
  2. Create a regular unit test which launches an inner isolated test runner, and runs the sample fixture.
  3. Retrieve the output of the inner test runner and assert over the test log.
The Gallio framework has everything you need to create an isolated test runner. But in order to make the things easier, the Gallio SDK (you can find the SDK under %gallio_install_path%\sdk) contains a couple of handy helper classes for that very purpose. It provides in particular a BaseTestWithSampleRunner class that you can use as a base class of you main fixture, and a [RunSample] attribute to easily target the nested explicit sample fixtures.

Here is a simple example that shows how to test the [BooleanData] attribute that we did create last time.
[TestFixture, RunSample(typeof(SampleFixture))]
public class BooleanDataAttributeTest : BaseTestWithSampleRunner
{
[Test]
public void Test()
{
var runs = GetTestStepRuns(typeof(SampleFixture), "Test");
var logs = runs.Select(GetLog).Where(x => x.Length > 0);
Assert.AreElementsEqualIgnoringOrder(new[] { "value=True", "value=False" }, logs);
}

[TestFixture, Explicit]
internal class SampleFixture
{
[Test]
public void Test([BooleanData] bool value)
{
TestLog.Write("value={0}", value);
}
}
}
