I actually prefer to use the DescriptionAttribute over a summary tag. The reason being that the value of the Description attribute will show up in a results file. It makes failures easier to understand when you're just looking at a log file
[TestMethod,Description("Ensure feature X doesn't regress Y")]
public void TestFeatureX42() {

}
