Hi,

Any good examples out there (I couldn't find any) of assert_throws? I
would love to know also why its first argument is a symbol...

Thanks
Mike

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

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

require 'test/unit'

def f
throw
end

def g
raise
end

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