routes - Ruby on Rails：如何使用具有唯一 ID 的 rspec 测试路线？

Question

我正在尝试这样做：

• 如何使用 rspec-rails 测试控制器？

我的测试如下：

describe "User pages" do

subject { page }

describe "edit" do
  let(:user) { FactoryGirl.create(:user) }
  before do
    log_in user 
    #visit edit_user_path(user) <-- did not work
  end

describe "page" do
  it "should render edit page" do
    get :edit, :id => user.id
    should have_selector('h1',    text: "Update")
    should have_selector('h2',    text: user.username)
    should have_selector('title', text: "Edit user")
  end
end

describe "with invalid information" do
  before { click_button "Save changes" }
  it { should have_content('error') }
end

结尾

我尝试添加get :edit, :id => user.id，但它引发了异常：

Failure/Error: get :edit, :id => user.id
 ArgumentError:
   bad argument (expected URI object or URI string)

还有什么我想念的吗？

Answer 1

1）确保您的测试文件有一个块，如：

 describe UsersController do
   # your tests here
 end

2）尝试像这样重写get

 it "should render edit page" do
    get :edit, :id => user.to_param
    should have_selector('h1',    text: "Update")
    # ...
 end

Answer 2

试试这个

describe "page" do
  it "should render edit page" do
    p = FactoryGirl.create(:user)
    get :edit, :id => p.id
    should have_selector('h1',    text: "Update")
    should have_selector('h2',    text: user.username)
    should have_selector('title', text: "Edit user")
  end
end

Answer 3

我最终这样做了：

visit edit_user_path(user.id) 

我不确定是否阅读了有关哪种方法（获取与访问）是首选的内容。
