rspec的should方法

 

 

      第一行result应该等于5；

 

 

      第二行result应该包含5；

 

 

      第三行result应该响应hello；

 

 

      第四行lambda匿名函数应该抛出错误信息“Nothing find！”；

 

 

      第五行result应该匹配正则表达式；

 

 

      第六行期望代码块能把bug状态从“open”改为“fixed”；

 

 

      第七行result应该为空；

 

 

      Should() 方法表示肯定，还有should_not()方法表示否定，该方法的工作机制是先执行should或者should_not后边的代码，返回一个 match对象，进而把此match对象作为参数传给should()或者should_not()方法，和拥有对象句柄的本地match对象作对比校 验，若匹配不成功，返回相应信息

 

测试controller

 

classHomeController<ApplicationController  def login
    @person=Person.where(name: params[:person][:name])if@person.blank?
      redirect_to root_path          
    else
      redirect_to people_path
    end  endend

 

describe HomeControllerdo
  render_views
  it "Logs in Person with non-blank name"do
    person =Factory(:Person, name:"non-blank name")
    get :login
    response.should redirect_to(people_path)end
  it "does not log in Person with blank name"do
    person =Factory(:Person, name:"")# blank name
    get :login
    response.should redirect_to(root_path)endend

 

处理文字编码与相应的引用

 

describe "admin/roles/index"do

before(:each) do

@ability = Object.new

 @ability.extend(CanCan::Ability)

 controller.stub(:current_ability) { @ability }

  view.stub(:current_ability) { @ability }

assign(:roles, Role.paginate(:page => params[:page],:per_page => 10).order("updated_at DESC"))

end

 

it "has a create link for that role inside admin" do @ability.can :create, Role render if Role.count > 0 rendered.should have_selector("div") do |new_a| new_a.should have_selector "a", :href => new_admin_role_path, :content => "添加" end end end

 

it "has a destroy link for that role inside admin" do

  @ability.can :destroy, Role

  render

  if Role.count > 0

    rendered.should have_selector("tr td") do |destroy_a|

      destroy_a.should have_selector "a",

      :href => admin_role_path(Role.first),

      :"data-method" => "delete",

      :"data-confirm" => "删除之后，该角色下的用户将无该角色下的权限。确定删除吗?",

      :rel => "nofollow",

      :content => "删除"

    end

  end

end

 

it "has a update link for that role inside admin" do @ability.can :update, Role render if Role.count > 0 rendered.should have_selector("tr td") do |update_a| update_a.should have_selector "a", :href => "/admin/roles/"+Role.first.id+"/edit", :content => "修改" end end end

 

it "renders a list of admin/roles" do role = Role.first @ability.can :destroy, Role @ability.can :update, Role render # Run the generator again with the --webrat flag if you want to use webrat matchers allow_message_expectations_on_nil assigns[:roles].stub!(:total_pages).and_return(1) assert_select "tr>td", :text => role.name.to_s, :count => 1 assert_select "tr td", :text => role.description.to_s, :count => 1 mycount = Role.count assert_select "a", :html => "修改",:count => mycount < 10?mycount:10 assert_select "a", :html => "删除", :count => mycount < 10?mycount:10 end end
