#assert_throw checks for a Kernel#throw, which takes a Symbol.
Perhaps you were after #assert_raise ?

--------------------

require 'test/unit'

def f
  throw :x
end

def g
  raise
end

class T < Test::Unit::TestCase
  def test_a
    assert_throws(:x){f}  # pass
    assert_throws(:y){f}  # fail
  end
  def test_b
    assert_raise(RuntimeError ){g}  # pass
    assert_raise(ArgumentError){g}  # fail
  end
end
