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 view spec that stubs a helper method
  8. request.path_parameters should match Rails by using symbols for keys
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" do
  it "displays all the widgets" do
    assign(:widgets, [
      stub_model(Widget, :name => "slicer"),
      stub_model(Widget, :name => "dicer")
    ])

    render

    rendered.should =~ /slicer/
    rendered.should =~ /dicer/
  end
end
When
I run rspec spec/views
Then
the examples should all pass
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" 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 =~ /slicer/
      rendered.should =~ /dicer/
    end
  end
end
When
I run rspec spec/views
Then
the examples should all pass
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 =~ /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 examples should all pass
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 =~ /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 examples should all pass
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 =~ /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 examples should all pass
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 =~ /directly rendered/
  end
end
When
I run rspec spec/views
Then
the examples should all pass
passing view spec that stubs a helper method
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' do
  before do
    view.stub(:admin?).and_return(true)
  end

  it 'checks for admin access' do
    render
    rendered.should =~ /Secret admin area/
  end
end
When
I run rspec spec/views/secrets
Then
the examples should all pass
request.path_parameters should match Rails by using symbols for keys
Given
a file named "spec/views/widgets/index.html.erb_spec.rb" with: 
require "spec_helper"

describe "controller.request.path_parameters" do
  it "matches the Rails environment by using symbols for keys" do
    [:controller, :action].each { |k| controller.request.path_parameters.keys.should include(k) }
  end
end
When
I run rspec spec/views
Then
the examples should all pass
