查询参数和assert_generates/assert_routing - 我缺少什么？

我想我已经介绍了使用查询参数测试路由的排列，但没有一种方法通过。

在我的 paths.rb 中，我有以下内容：

resources :items

然后对于我的功能测试我有：

require 'ruby-debug'
require 'test_helper'

class ItemsControllerTest < ActionController::TestCase
  # Failure: test_assert_generates_using_params_and_extras(ItemsControllerTest) [test/functional/items_controller_test.rb:7]: The generated path <"/items/1/edit"> did not match <"/items/1/edit?q=abc">
  test "assert_generates using params and extras" do
    assert_generates '/items/1/edit?q=abc',
                     { :controller => 'items', :action => 'edit', :id => '1', :q => 'abc' },
                     {},
                     { :q => 'abc' }
  end

  # Failure: test_assert_generates_using_only_params(ItemsControllerTest) [test/functional/items_controller_test.rb:15]: found extras <{:q=>"abc"}>, not <{}>
  test "assert_generates using only params" do
    assert_generates '/items/1/edit?q=abc',
                     { :controller => 'items', :action => 'edit', :id => '1', :q => 'abc' }
  end

  # Failure: test_assert_generates_using_using_only_extras(ItemsControllerTest) [test/functional/items_controller_test.rb:21]: found extras <{}>, not <{:q=>"abc"}>
  test "assert_generates using using only extras" do
    assert_generates '/items/1/edit?q=abc',
                     { :controller => 'items', :action => 'edit', :id => '1' },
                     {},
                     { :q => 'abc' }
  end

  # Failure: test_assert_routing_using_params_and_extras(ItemsControllerTest) [test/functional/items_controller_test.rb:29]: The generated path <"/items/1/edit"> did not match <"/items/1/edit?q=abc">
  test "assert_routing using params and extras" do
    assert_routing '/items/1/edit?q=abc',
                     { :controller => 'items', :action => 'edit', :id => '1', :q => 'abc' },
                     {},
                     { :q => 'abc' }
  end

  # Failure: test_assert_routing_using_only_params(ItemsControllerTest) [test/functional/items_controller_test.rb:37]: found extras <{:q=>"abc"}>, not <{}>
  test "assert_routing using only params" do
    assert_routing '/items/1/edit?q=abc',
                     { :controller => 'items', :action => 'edit', :id => '1', :q => 'abc' }
  end

  # Failure: test_assert_routing_using_using_only_extras(ItemsControllerTest) [test/functional/items_controller_test.rb:43]: found extras <{}>, not <{:q=>"abc"}>  
  test "assert_routing using using only extras" do
    assert_routing '/items/1/edit?q=abc',
                     { :controller => 'items', :action => 'edit', :id => '1' },
                     {},
                     { :q => 'abc' }
  end
end

我本希望 *_using_params_and_extras 测试能够通过 - 我错过了什么？

也许你已经明白了这一点。我今天遇到了同样的问题，直到我发现这个问题，注意到额外选项的存在，最后再次阅读了assert_routing的文档。您必须从 url 中删除 q=abc 并将其放入 extras 哈希和 options 哈希中。

所以尝试这样的事情：

assert_routing(
  'items/1/edit',
  {:controller => 'items', :action => 'edit', :id => '1', :q => 'abc'},
  {},
  {:q => 'abc'}
)
