Question

我的应用程序有两个模型：用户和员工，他们的关系是用户has_many员工。

当我尝试为员工控制器编写Rspec测试用例时：

describe "GET 'edit'" do
  it "should get user/edit with log in" do
    log_in(@user)
    employee = mock_model(Employee, :id=>1, :user_id=>@user.id)
    get :edit, :id=>employee
    response.should be_success
  end
end

我的结果是：

....F

Failures:

  1) EmployeesController GET 'edit' should get user/edit with log in
     Failure/Error: get :edit, :id=>employee
       Mock "Employee_1" received unexpected message :to_ary with (no args)
     # C:in `find'
     # ./app/controllers/employees_controller.rb:41:in `edit'
     # ./spec/controllers/employees_controller_spec.rb:51:in `block (3 levels) in '

有人可以帮我解决这个问题吗？感谢

我认为问题是你正在使用mock_model，如果你在模型上调用一个你没有明确创建期望的方法，它会抛出错误。在这种情况下，您可以使用stub_model创建员工，因为您不对实际对模型进行的调用执行检查。

describe "GET 'edit'" do

  it "should get user/edit with log in" do
    log_in(@user)
    employee = stub_model(Employee, :id=>1, :user_id=>@user.id)
    get :edit, :id=>employee
    response.should be_success
  end
end

Rails能够从真实的模型实例推断ID，这就是它的工作原理：

@employee = Employee.create
get :edit, :id => @employee

这不适用于mock_model，原因我不清楚。您只需明确传入ID：

  employee = mock_model(Employee, :id => 1, :user_id=>@user.id)
  get :edit, :id => employee.id # or just :id => 1

我认为问题出在mock_model上，你可以使用double。

describe "GET 'edit'" do

  it "should get user/edit with log in" do
    log_in(@user)
    employee = double('employee', :id=>1, :user_id=>@user.id)
    get :edit, :id=>employee
    response.should be_success
  end
end

RSpec错误：模拟“Employee_1”收到意外消息：to_ary with（no args）
