Analogue to assert.throws. Should be used to self-document when the expected failure mode for a test case is for an exception to be thrown. Will output a stack trace through doassert (note that output generated for uncaught exceptions currently does not even include a line number).

assert.doesNotThrow = function(func, params, msg) { ... };
assert.doesNotThrow.automsg = function(func, params) { ... };

Example usage:

assert.doesNotThrow(function() { db.foo.find({a:{$gt:0}}).itcount(); },
                    [],
                    "testing that the $gt operator is recognized");
