Testing a render layout statement in a controller

Testing RSpec
1

I am new to rSpec and I am writing a test for a controller which has
already been developed

This is the example in my reports_controller_spec.rb:

it “should render the layouts/menu template” do
get :select_missing_persons
response.should render_template(“layouts/menu”)
end

and this is the method in the reports_controller.rb

def select_missing_identifiers
render(:layout => “layouts/menu”)
end

I am getting the following output when running autotest:

‘ReportsController should render the layouts/menu template’ FAILED
expected “layouts/menu”, got “reports/select_missing_persons”
./spec/controllers/reports_controller_spec.rb:39:
script/spec:4:

Here, I was trying to test if the out put displays with a layouts/menu
template.
Can somebody help on how you test the render(:layout => “layouts/
menu”) statement in a controller or this is supposed to be tested in
the view?

Try this:

render(:layout => “layouts/menu”) and return

Try to write a customized matcher, here is an example

custom matchers

#---------------------

class UseLayout

def initialize(expected)

@expected = 'layouts/' + expected + '_layout'

end

def matches?(controller)

@actual = controller.layout

#@actual.equal?(@expected)

@actual == @expected

end

def failure_message

return "use_layout expected #{@expected.inspect}, got

#{@actual.inspect}", @expected, @actual

end

def negative_failure_message

return "use_layout expected #{@expected.inspect} not to equal

#{@actual.inspect}", @expected, @actual

end

end

def use_layout(expected)

UseLayout.new(expected)

end

Thanks Bartz, I used your input to try a controller line of
format.html { render :action => “show” }
and rspec of
response.should render_template( :(controller name) => “/show”)

I tried it with and without the “and return” and both worked.
