> In cases where the expected output does not match the actual output, the Errors class will treat the error message created by the TestDriver.checkTypesAndLogError(...) method as a format string.  If either the Expected or Actual Output value contains a '%' character, the String.format will result in some type of IllegalFormatException.  In my case, I received an UnknownFormatConversionException with "%D" in the expected output.
> Fortunately, this behavior is only triggered if the unit test is in error, but it can make tracking down the source of the issue hard to find.
