Feature: Views are stubbed by default
By default, controller specs stub views with a template that renders an empty
string instead of the views in the app. This allows you specify which view
template an action should try to render regardless of whether the template
compiles cleanly.
NOTE: unlike rspec-rails-1.x, the real template must exist.
Scenario: Expect a template that is rendered by controller action (passes)
Given a file named "spec/controllers/widgets_controller_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe WidgetsController, type: :controller do
describe "index" do
it "renders the index template" do
get :index
expect(response).to render_template("index")
expect(response.body).to eq ""
end
it "renders the widgets/index template" do
get :index
expect(response).to render_template("widgets/index")
expect(response.body).to eq ""
end
end
end
"""
When I run `rspec spec`
Then the examples should all pass
Scenario: Expect a template that is not rendered by controller action (fails)
Given a file named "spec/controllers/widgets_controller_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe WidgetsController, type: :controller do
describe "index" do
it "renders the 'new' template" do
get :index
expect(response).to render_template("new")
end
end
end
"""
When I run `rspec spec`
Then the output should contain "1 example, 1 failure"
Scenario: Expect empty templates to render when view path is changed at runtime (passes)
Given a file named "spec/controllers/things_controller_spec.rb" with:
"""ruby
require "rails_helper"
RSpec.describe ThingsController, type: :controller do
describe "custom_action" do
it "renders an empty custom_action template" do
controller.prepend_view_path 'app/views'
controller.append_view_path 'app/views'
get :custom_action
expect(response).to render_template("custom_action")
expect(response.body).to eq ""
end
end
