我试图测试成功注册成功模板的条件,由以下控制器代码呈现
def create
@user = User.new(params[:user])
if @user.save
render :template => "success"
else
flash[:notice] = "Oops Somethings not quite right! :("
render :action => "new"
end
end
我使用以下规范来测试这个代码
before(:each) do
@user = User.new
@user.attributes = valid_attributes
@params = valid_attributes
@user.stub!(:save).and_return(true)
end
def do_post
post :create
end
it "should create new user " do
count = User.count
do_post
user = User.new(@params)
user.save.should eql(true)
User.count.should eql(count + 1)
end
it "should render the success page on successful signup" do
do_post
@user.save
response.should render_template("success") if @user.save
end
1) 'UsersController handling POST /users should render the success page on successful signup' Failed expected "success",got "users/new.html.erb" ./spec/controllers/users_controller_spec.rb:67:
成功视图是存储在views / users /中没有操作的模板.我猜想我犯了一个非常根本的错误,并希望得到一些帮助.
解决方法
您在测试中存储@user变量,但控制器将实例化一个新实例,因此存根不会到位.
在这种情况下使用存根不仅仅是为了模拟成功的保存调用不是一个好主意.为什么不提供有效数据,并确保操作成功？
以下代码用于RSpec> 2.1它使用expect语法.
before(:each) do
@params = valid_attributes
end
it "should create new user" do
@_before = User.count
post :create,:user => @params
expect(assigns(:user)).to_not be_new_record
expect(User.count).to eq(@_before + 1)
end
it "should render the success page on successful signup" do
post :create,:user => @params
expect(response).to be_successful
expect(response).to render_template("success")
end
最后,改变
render :template => "success"
至
render :action => "success"
对于以前的RSpec版本,或者如果您必须使用应用程序语法,请使用
before(:each) do
@params = valid_attributes
end
it "should create new user" do
@_before = User.count
post :create,:user => @params
assigns(:user).should_not be_new_record
User.count.should == (@_before + 1)
end
it "should render the success page on successful signup" do
post :create,:user => @params
response.should be_successful
response.should render_template("success")
end
