如何断言 Rails 集成测试中没有路由匹配？

发布于 2024-10-14 11:58:13 字数 474 浏览 2 评论 0原文

我有一个 Rails 3 集成测试来测试我的路线。它包含以下测试：

assert_routing(
    "/#{@category.url.path}/#{@foo.url.path}",
    { :controller => 'foo', :action => 'show', :category => @category.to_param, :foo => @foo.to_param }
)

我还想测试没有路由匹配的情况。显然，在这种情况下测试生成没有意义，所以我只需要断言_识别的逆。我希望能够做这样的事情：

assert_not_recognized('/adfhkljkdhasjklhjkldfahsjkhdf')

有什么想法，除了将assert_recognizes包装在assert_raises块中之外（这实际上并没有那么可怕，现在我想起来了）？

I have a Rails 3 integration test which tests my routes. It contains tests such as:

assert_routing(
    "/#{@category.url.path}/#{@foo.url.path}",
    { :controller => 'foo', :action => 'show', :category => @category.to_param, :foo => @foo.to_param }
)

I would also like to test a case where no routes should match. Obviously, testing generation has no meaning in this case, so I just need the inverse of assert_recognizes. I'd like to be able to do something like this:

assert_not_recognized('/adfhkljkdhasjklhjkldfahsjkhdf')

Any ideas, short of wrapping assert_recognizes in an assert_raises block (which is actually not so terrible, now that I think about it)?

在 Rails 4 中，有一种类似的方法可以通过在 UrlGenerationError 异常上断言来检查这一点：

def test_no_routes_match_when_neither_foo_nor_bar_exist
  assert_raises(ActionController::UrlGenerationError) do
    get '/category/this-is-neither-a-foo-nor-a-bar'
  end
end

There is a similar way for checking this in Rails 4 by asserting on the UrlGenerationError exception:

def test_no_routes_match_when_neither_foo_nor_bar_exist
  assert_raises(ActionController::UrlGenerationError) do
    get '/category/this-is-neither-a-foo-nor-a-bar'
  end
end

我最终这样做了：

  def test_no_routes_match_when_neither_foo_nor_bar_exist
    assert_raises(ActionController::RoutingError) do
      assert_recognizes({}, '/category/this-is-neither-a-foo-nor-a-bar')
    end
  end

有点傻，但它完成了工作。

请注意，这不适用于 Rails 4。请参阅下面的答案了解 Rails 4 解决方案。

I ended up doing this:

  def test_no_routes_match_when_neither_foo_nor_bar_exist
    assert_raises(ActionController::RoutingError) do
      assert_recognizes({}, '/category/this-is-neither-a-foo-nor-a-bar')
    end
  end

Slightly silly, but it gets the job done.

Note that this does not work with Rails 4. See the answer below for a Rails 4 solution.

通过调用#recognize_path，您不会收到错误。相反，您会收到错误，但随后您找到了您正在寻找的线索。

test "No routes match when neither_foo_nor_ bar exist" do
  begin 
    assert_not(Rails.application.routes.recognize_path(
        'category/this-is-neither-a-foo-nor-a-bar'))
  rescue ActionController::RoutingError => error
    assert error.message.start_with? "No route matches"
  end
end

By calling #recognize_path you wont receive a false. Instead you'll get an error, but then you found the clue you were looking for.

test "No routes match when neither_foo_nor_ bar exist" do
  begin 
    assert_not(Rails.application.routes.recognize_path(
        'category/this-is-neither-a-foo-nor-a-bar'))
  rescue ActionController::RoutingError => error
    assert error.message.start_with? "No route matches"
  end
end
