stub template

In order to isolate view specs from the partials rendered by the primary
view, rspec-rails (since 2.2) provides the stub_template method.

Scenarios

stub template that does not exist

Given

a file named "spec/views/gadgets/list.html.erb_spec.rb" with:

require "spec_helper"

describe "gadgets/list.html.erb" do
  it "renders the gadget partial for each gadget" do
    assign(:gadgets, [
      mock_model(Gadget, :id => 1, :name => "First"),
      mock_model(Gadget, :id => 2, :name => "Second")
    ])
    stub_template "gadgets/_gadget.html.erb" => "<%= gadget.name %><br/>"
    render
    rendered.should =~ /First/
    rendered.should =~ /Second/
  end
end

And

a file named "app/views/gadgets/list.html.erb" with:

<%= render :partial => "gadget", :collection => @gadgets %>

When

I run "rspec spec/views/gadgets/list.html.erb_spec.rb"

Then

the output should contain "1 example, 0 failures"

stub template that exists

Given

a file named "spec/views/gadgets/edit.html.erb_spec.rb" with:

require "spec_helper"

describe "gadgets/edit.html.erb" do
  before(:each) do
    @gadget = assign(:gadget, stub_model(Gadget))
  end

  it "renders the form partial" do
    stub_template "gadgets/_form.html.erb" => "This content"
    render
    rendered.should =~ /This content/
  end
end

When

I run "rspec spec/views/gadgets/edit.html.erb_spec.rb"

Then

the output should contain "1 example, 0 failures"
