When writing automated tests I get tired of typing this over and over again:

[Test]
public void when_foo_happens_then_bar() {
      //Arrange

      //Act

      //Assert
}

So I made a ReSharper Live Template:

	[Test]
	public void $NAME$() {
		//Arrange

		//Act

		//Assert
		Assert.Fail();
	}

Now getting test definitions into the test class goes more like this:

“hmm, what should I test?  How about,

testwhen_x_then_y
testwhen_i_then_j …”

With this template I found that not only do I saving typing time, but its also helped me brainstorm a bunch of tests quickly without distracting myself with the format.

You can type it yourself, or download it from github and import.

To Import:  Resharper -> Tools -> Template Explorer -> Live Templates Tab -> Import button

UPDATE 6/6/2015:  I have updated the template so that there is one for NUnit and another for the .NET Test Framework.  Get the import file here: https://github.com/brentonc/bcutils/tree/master/ReSharper
