Defined in:
lib/spec/rails/example/view_example_group.rb

Overview

View Examples live in $RAILS_ROOT/spec/views/.

View Specs use Spec::Rails::Example::ViewExampleGroup, which provides access to views without invoking any of your controllers. See Spec::Rails::Expectations::Matchers for information about specific expectations that you can set on views.

Example

describe "login/login" do
  before do
    render 'login/login'
  end

  it "should display login form" do
    response.should have_tag("form[action=/login]") do
      with_tag("input[type=text][name=email]")
      with_tag("input[type=password][name=password]")
      with_tag("input[type=submit][value=Login]")
    end
  end
end

#render(*args) ⇒ Object

Renders a template for a View Spec, which then provides access to the result through the response. Also supports render with :inline, which you can use to spec custom form builders, helpers, etc, in the context of a view.

Examples

render('/people/list')
render('/people/list', :helper => MyHelper)
render('/people/list', :helpers => [MyHelper, MyOtherHelper])
render(:partial => '/people/_address')
render(:inline => "<% custom_helper 'argument', 'another argument' %>")

See Spec::Rails::Example::ViewExampleGroup for more information.

#template ⇒ Object

This provides the template. Use this to set mock expectations for dealing with partials

Example

describe "/person/new" do
  it "should use the form partial" do
    template.should_receive(:render).with(:partial => 'form')
    render "/person/new"
  end
end
