如何断定Rails集成测试中没有路由匹配? [英] How can I assert that no route matches in a Rails integration test?

问题描述

我有一个Rails 3集成测试，可以测试我的路线.它包含以下测试:

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 }
)

我还想测试一种路由不匹配的情况.显然，在这种情况下，测试生成没有任何意义，因此我只需要相反的assert_recognizes.我希望能够做这样的事情:

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')

除了将assert_recognizes包装在assert_raises块中之外，还有什么想法(实际上，考虑到我现在考虑的并不那么糟糕)?

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

推荐答案

我最终这样做:

  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，但是可以完成工作.

Slightly silly, but it gets the job done.

请注意，此不能与Rails 4一起使用.请参阅下面的答案以了解Rails 4解决方案.

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