view spec

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

Scenarios
  1. passing spec that renders the described view file
  2. passing spec with before and nesting
  3. passing spec with explicit template rendering
  4. passing spec with rendering of locals in a partial
  5. passing spec with rendering of locals in an implicit partial
  6. passing spec with rendering of text
  7. passing spec with rendering of Prototype helper update
  8. spec with view that accesses helper_method helpers
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"
Then
the output should contain "1 example, 0 failures"
