        capybara: NOT SUPPORTED
      - follow_redirect!
      - Scenarios
        
        Specify managing a Resource with Rails integration methods
        
        Ex: request to create a resource and expect
        the response
        
        Requesting a JSON response
        
        headers = { "ACCEPT" => "application/json" }
        post '/widget', params: { widget: { name: 'my widget' } }, headers: headers
        expect( response.content_type ).to eq( "application/json" )
        expect( response ).to have_http_status( :created )
        
        Providing JSON data
        
        headers = { "CONTENT_TYPE" => "application/json" }
        post "/widgets", params: ' { "widgets": { "name": "my widget" } ', headers: headers
        expect( response ).to redirect_to( assigns(:widget) )

        Scenarios
        
        Create widget drives by Capybara
        
        visit "/widgets/new"
        click_button "Create new"
        expect(page).to have_text("Success")
      - require capybara gem
  - - - test content of view template, without invoke controller
        
        assign(:widget, Widget.new)
        render
        expect(rendered).to match(/text/)
        
        assign : set instance variable in view
        
        render: render the view
        
        rendered: result of the render
        
        Scenarios
        
        with :template option
        
        render :template => "widgets/widget.html.erb"
        
        with :layout option
        
        render :template => "widgets/widget.html.erb", :layout => "layouts/inventory"
        
        render :locals in partial
        
        render :partial => "widgets/widget.html.erb", :locals => {:widget => widget}
        
        Implicit partial
        
        render "widgets/widget", :widget => widget
        
        render plain text
        
        render plain: "hello world"
        
        Stub helper method
        
        allow(view).to receive(:admin?).and_return(true)
        
        controller.request.path_parameters
        
        [:controller, :action].each { | key | expect(controller.request.path_parameters.keys).to include(key) }
        
        controller.request.fullpath
        
        expect(controller.request.fullpath).to eq widgets_path
        
        controller.request.fullpath with extra parameter
        
        controller.extra_params = { :id => widget.id }
        expect(controller.request.fullpath).to eq widget_path(widget.id)
        
        Stub Template
        
        ដើម្បី isolate primary view ពី partial
        
        Stub template ដែលមិនមាន
        
        assign(:widgets, [ double(name: "First"), double(name: "Second") ])
        stub_template "widgets/_widgets.html.erb", "<%= widget.name %>"
        render
        expect(rendered).to match(/First/)
        expect(rendered).to match(/Second/)
  - - - expose helper object
      - Access instance variable
        
        assign(:title, "My title") expect(helper.page_title).to eq "My title"
        
        module ApplicationHelper def page_title @title end end
