Issue #3219 has been updated by fxn (Xavier Noria).


Not sure I understand this ticket.

If I write a generic predicate foo? whose return value is undocumented and irrelevant, I should be able to test it like this?

    assert obj.foo?

 Hi,
 
 Test::Unit::Assertions#assert now passes non-boolean values
 (neither true nor false).
 
 It is not only an incompatibility against former TestUnit, also
 makes wrong tests (e.g., [ruby-core:29861]) passing.
