Asserting on case classes in ScalaTest

I see there's support for the Option type, but what about custom case classes?

I sort of want to do this:

result match {
  case SuccessCase(values) => {
    values.foo should be ("bar")
  }
  case FailureCase => // should fail test, but how to say this in ScalaTest?
}

Bill Venners also suggested writing a custom matcher if writing these kinds of tests often:

Does this work, assuming the case you want is DesiredCase?

result match {
  case DesiredCase(values) => {
    values.foo should be ("bar")
  }
  case _ => {
    fail("Not DesiredCase")
  }
}

You can use fail() to fail a test on purpose, as in case FailureCase => fail("err msg"), but I'm not sure I understand what you're after. Perhaps you can show more of the code or elaborate to clarify the question?
