/**
 * Hammer ObjectName, making sure it spots all malformed inputs.
 * <p/>
 * This may look like overkill but it's not.  I want each
 * permutation to run independantly for full test coverage.
 * <p/>
 * This suite has twice as many tests (about 60) as my last
 * testcase - and for that it caught one extra bug for me.
