我有一个带有 3 个模型的 Rails 应用程序：模型image, profile and user
之间的关系如下：用户 has_one profile 用户 has_many images image 和 profile 属于用户
我有通过脚手架为我的初始用户模型创建的功能测试，但现在其中一些不再工作了。我想编写一个测试，它将使用嵌套属性等覆盖整个表单。 现在，所有数据库表都由单个页面上的嵌套表单填充，并且我的一些功能测试失败并出现错误。以下是相关测试和错误：
test "should create user" do
assert_difference('User.count') do
post :create, :user => { :email => "testing@gmail.com",
:first_name => "langlylo",
:last_name => "aaaaa",
:orientation => "Straight",
:password => "secret",
:password_confirmation => "secret",
:gender => "Male",
:location => "London" }
end
test "should show user" do
get :show, id: @user
assert_response :success
end
test "should update user" do
# @user = user.authenticate
put :update, :id => @user.to_param, :user => @user
assert_redirected_to @user
end
1) Failure:
test_should_create_user(UsersControllerTest) [/home/tim/fairym/test/functional/users_controller_test.rb:20]:
"User.count" didn't change by 1.
<4> expected but was
<3>.
2) Error:
