Assert_Select problem with * selector

Reported by diabolo | October 29th, 2008 @ 07:24 AM | in 2.x

Given a response containing the following

<div id='cart'>
</div>

and the desire to test that my cart div is empty

The following don't work

assert_select("div#cart") do
  assert_select("*",0)
end

assert_select("div#cart", 0) do
  assert_select("*")
end

Whilst

assert_select("div#cart>*", 0)

does succeed.

- State changed from “new” to “invalid”
That is normal: when given a block assert_select tries to match the element specified (in this case div#cart) and then yields the matches. so you should be doing
```
assert_select("div#cart") do |elements|
  elements.each {|element| assert_select("*",0)}
end
```
Your code on the other hand asserts that div#cart exists and then asserts that there are no elements at the top level rather than asserting that there are no elements that are children of the match.
