I found I didn’t need format.js for the assertions to work. Do you think format.js should be included anyway to ensure the header is set correctly?

I had the rails syntax confused with the ARTS plugin. in rails, you would do

assert_select_rjs :replace_html, “membership-action” do
assert_select ’span’, :text => ‘Some content’
end

You would have to wrap the content in a html element, like a span. I am not sure if assert_select can find text nodes

assert_select_rjs :replace_html, “membership-action”, “Some Content”

… but it’s not working. For example,

assert_select_rjs :replace_html, “happy_div”, “blah”

… will always pass regardless of whether the html content matches or not.


old_count = Membership.count
delete :destroy, :id => 1
assert_equal old_count-1, Membership.count


This is a fairly new method. Changeset here: http://dev.rubyonrails.org/browser/trunk/activesupport/lib/active_support/core_ext/test/difference.rb?rev=6647

Instead of

old_count = Membership.count
assert_equal old_count-1,
Membership.count


You can do something more elegant, like this:


assert_difference 'Membership.count' do
delete :destroy, :id => 1
end
