Since the naming of a unit test method makes its purpose more meaningful, is it necessary to add a summary to a unit test method?

Example:

```
/// <summary>
/// Check the FormatException should be thrown when a give country data line contains a invalid number.
/// </summary>
[TestMethod]
public void FormatException_Should_Thrown_When_Parse_CountryLine_Containing_InvalidNumber()
{
  ...
}

```
