name = "{0} should be a palindrome" is the whole trick: {0} is a positional reference to the
single @ValueSource argument, and the console runner always quotes a String argument's own text
when it substitutes it in -- which is why the output reads "racecar" should be a palindrome
rather than requiring quotes inside the template itself. An earlier draft of this template used
name = "''{0}'' should be a palindrome", which doubles up with the console's own quoting and
renders as the much uglier '"racecar"' should be a palindrome -- fixed here before publishing by
simply dropping the extra quote marks from the template.
