检查 RSpec 中选择器的多个副本
我在 RSpec 中的一项测试遇到问题。有问题的测试应该通过检查页面上是否存在多个
it "should have more than one post" do
get :index
response.should have_selector("article", :class => "post", :count => 2)
end
由于某种原因，尽管在调试输出中显示
Failures:
1) PostsController GET 'index' should have more than one posts
Failure/Error: response.should have_selector("article", :class => "post", :count => 2)
expected following output to contain a <article class='post'/> tag:
请注意，如果我删除 :count =>; 2 选项测试通过，没有发生任何事件。
有谁知道为什么这个测试失败？
I'm having a problem with one of my tests in RSpec. The test in question is supposed to test whether there is more than one post on the index page, by checking for the existence of more than one <article class="post"> tag on the page. My current implementation looks like this:
it "should have more than one post" do
get :index
response.should have_selector("article", :class => "post", :count => 2)
end
For some reason this test fails, despite showing multiple instances of the <article class="post"> tag in the debug output. The specific error it give is
Failures:
1) PostsController GET 'index' should have more than one posts
Failure/Error: response.should have_selector("article", :class => "post", :count => 2)
expected following output to contain a <article class='post'/> tag:
Note that if I remove the :count => 2 option the test passes without incident.
Does anyone know why this test is failing?

我猜你在 RSpec 下使用 Capybara 或者 Webrat？使用 count 选项，您的测试断言响应恰好包含 2 个帖子，而不是至少 2 个。最小选项是否满足您的要求？
请参阅 https://github.com/jnicklas/capybara/ blob/master/lib/capybara/node/matchers.rb 和 http://rubydoc.info/github/jnicklas/capybara /master/Capybara/Node/Matchers#has_selector%3F-instance_method
I'm guessing you are using Capybara under RSpec here or Webrat? With the count option your test is asserting that the response contains exactly 2 posts, rather than at least 2. Does the minimum option do what you want?
