Testing render :text without has_text

A controller I’m trying to test simply delivers a text string to the
client, which then demarshalls it to retrieve some objects. I want to
test that the returned string is correct.

I don’t want to compare the string character-by-character with
response.has_text because that ties me to the implementation of the
Marshall class. Instead, I just want to demarshall the string and
compare that with the expected objects. To do this, I need RSpec to
give me the complete text string that’s rendered by the controller.

Here’s the controller:

class StatsController < ApplicationController
layout nil

def query
reports = StatisticsReporter.query params[:query_params]
render :text => Marshal.dump(reports)
end
end

And here’s the test:

describe StatsController do
before :each do
@query_params = { :foo => :bar }
end

it “should return a demarshallable string of the reports” do
reports = [
StatisticsReport.new(:date => nil),
StatisticsReport.new(:bytes_transferred => 0)
]
StatisticsReporter.should_receive(:query).and_return reports

get :query, :query_params => @query_params

 # PROBLEM CODE (the equality test needs tweaking, but you get the

idea)
Marshal.load(response.what_goes_here?).should == reports
end
end

(This code may look familiar to one member of this list…:slight_smile:

Can this be done?

Try this:

Marshal.load(response.body).should == reports

Dang! I dumped response.methods and tried everything that looked
likely, but I guess I missed that one. Thanks!

Just to preserve my sanity in the future, is there a place where this
is documented?
