Just FWIW, add_assertion expects a @_result object. I needed to call
assert_redirected_to, and was running into similar problems. You
could set it up before each call to assert (@_result =
Test::Unit::TestResult.new), though this adds a dependency on
Test:Unit which may or may not be desirable. You could set up a fake
object with an add_assertion method, and assign that to @_result.
...however, these are all hacks that are just there as a workaround,
and I'm guessing there's a much better way of doing this.
