>
> Often, when researching intermittent regression test errors, an assertion on
> a result set fails, but the error report only shows which column in which row
> first fails to meet expectations. It would be good if the assertion methods
> could dump the actual result set in such cases so we'd have more information
> to go on when trying to understand the cause of the problem.
