Question

Given a controller method like:

def show   @model = Model.find(params[:id])    respond_to do |format|     format.html # show.html.erb     format.xml  { render :xml => model }   end end 

What’s the best way to write an integration test that asserts that the return has the expected XML?

Answer 1

A combination of using the format and assert_select in an integration test works great:

class ProductsTest < ActionController::IntegrationTest   def test_contents_of_xml     get '/index/1.xml'     assert_select 'product name', /widget/   end end 

For more details check out assert_select in the Rails docs.
