view spec

View specs live in spec/views and render view templates in isolation.

Scenarios
passing spec that renders the described view file
Given
a file named "spec/views/widgets/index.html.erb_spec.rb" with:
require "spec_helper"

describe "widgets/index.html.erb" do
  it "displays all the widgets" do
    assign(:widgets, [
      stub_model(Widget, :name => "slicer"),
      stub_model(Widget, :name => "dicer")
    ])

    render

    rendered.should contain("slicer")
    rendered.should contain("dicer")
  end
end
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
passing spec with before and nesting
Given
a file named "spec/views/widgets/index.html.erb_spec.rb" with:
require "spec_helper"

describe "widgets/index.html.erb" do

  context "with 2 widgets" do
    before(:each) do
      assign(:widgets, [
        stub_model(Widget, :name => "slicer"),
        stub_model(Widget, :name => "dicer")
      ])
    end

    it "displays both widgets" do
      render

      rendered.should contain("slicer")
      rendered.should contain("dicer")
    end
  end
end
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
passing spec with explicit template rendering
Given
a file named "spec/views/widgets/widget.html.erb_spec.rb" with:
require "spec_helper"

describe "rendering the widget template" do
  it "displays the widget" do
    assign(:widget, stub_model(Widget, :name => "slicer"))

    render :template => "widgets/widget.html.erb"

    rendered.should contain("slicer")
  end
end
And
a file named "app/views/widgets/widget.html.erb" with:
<h2><%= @widget.name %></h2>
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
passing spec with rendering of locals in a partial
Given
a file named "spec/views/widgets/_widget.html.erb_spec.rb" with:
require "spec_helper"

describe "rendering locals in a partial" do
  it "displays the widget" do
    widget = stub_model(Widget, :name => "slicer")

    render :partial => "widgets/widget.html.erb", :locals => {:widget => widget}

    rendered.should contain("slicer")
  end
end
And
a file named "app/views/widgets/_widget.html.erb" with:
<h3><%= widget.name %></h3>
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
passing spec with rendering of locals in an implicit partial
Given
a file named "spec/views/widgets/_widget.html.erb_spec.rb" with:
require "spec_helper"

describe "rendering locals in a partial" do
  it "displays the widget" do
    widget = stub_model(Widget, :name => "slicer")

    render "widgets/widget", :widget => widget

    rendered.should contain("slicer")
  end
end
And
a file named "app/views/widgets/_widget.html.erb" with:
<h3><%= widget.name %></h3>
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
passing spec with rendering of text
Given
a file named "spec/views/widgets/direct.html.erb_spec.rb" with:
require "spec_helper"

describe "rendering text directly" do
  it "displays the given text" do

    render :text => "This is directly rendered"

    rendered.should contain("directly rendered")
  end
end
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
passing spec with rendering of Prototype helper update
Given
a file named "spec/views/widgets/prototype_update.html.erb_spec.rb" with:
require "spec_helper"

describe "render a Prototype helper update" do
  it "hides the status indicator" do

    render :update do |page|
      page.hide 'status-indicator'
    end

    rendered.should contain("Element.hide(\"status-indicator\")")
  end
end
When
I run "rspec spec/views"
Then
the output should contain "1 example, 0 failures"
spec with view that accesses helper_method helpers
Given
a file named "app/views/secrets/index.html.erb" with:
<%- if admin? %>
  <h1>Secret admin area</h1>
<%- end %>
And
a file named "spec/views/secrets/index.html.erb_spec.rb" with:
require 'spec_helper'

describe 'secrets/index.html.erb' do
  before do
    controller.singleton_class.class_eval do
      protected
        def admin?
          true
        end
        helper_method :admin?
    end
  end

  it 'checks for admin access' do
    render
    rendered.should contain('Secret admin area')
  end
end
When
I run "rspec spec/views/secrets"
