I found another reason to love open source NUnit over MSTest, NUnitEx. NUnitEx provides a fluent DSL to write NUnit assertions where Visual Studio intellisense is your guiding friend. I’m sure you’re thinking, “Yeah whatever, show me some code.”

[Test]
public void AdjacencyGraph_is_directed_by_default()
{
    var graph = new AdjacencyGraph<Task, TaskDependency>(DoNotAllowParallelEdges);
    graph.IsDirected.Should().Be.True();
}

Nice eh? graph.IsDirected is the property I want to test.  Everything after that is the NUnitEx extension methods. I know I find it much more readable than this:

[Test]
public void AdjacencyGraph_is_directed_by_default()
{
    var graph = new AdjacencyGraph<Task, TaskDependency>(DoNotAllowParallelEdges);
    Assert.IsTrue(graph.IsDirected);
}

I would also like to add that this syntax is likely to be included in NUnit 3, which would be excellent!
