Story for Rest

Testing RSpec
1

Hello all,

I’m trying to write a story for a rest resource.

Here’s what I have so far:

Story “Get prices for specific book”, %{
As a client
I want to get a list of prices for a specific book
So that I can use it on my own application
}, :type => RailsStory do

Scenario “Requesting /books/:id/prices using GET” do
Given “a regular rest request”

When "visiting", "/books/:id/prices" do |path|
  get path
end

Then "it should return an xml file"

end
end

How would I check that the format of my response is in xml? Also, is it
possible to check the content of an xml file, to make sure that it’s not
empty? Any other suggestions on what would make this story more
efficient?

Thanks again

Olivier D.

Attached is a custom matcher using hpricot, (and the spec for it) it has
a "have_xpath matcher for
checking xml.

I has an earlier one using rexml but hpricot is faster, you can read
about that here…

This new hpricot one is moslty based on someone elses work, and I’ll
credit them when I got my blog
entry on it done.

I know a lot of people that do hpricot or xpath-style stuff to test
XML. I really like my ghetto simple Hash.from_xml approach.

hash = Hash.from_xml response.body
hash[‘book’].should_not be_nil
hash[‘book’][‘price’].should == 123.45

You could probably wrap it up a bit more, but I like how clear and
straightforward it is.
