Question

因此，我在使某些RSpec测试失败时遇到了一些麻烦。无论我如何尝试它们总是通过，好吧，其中一项测试可以正常工作，并且我证实如果我修改正在测试的代码，它会失败。

我正在尝试测试对外部API进行的JSON响应的内容，以确保我的控制器正确地对这些返回的JSON对象进行了排序。

我在这里想念什么吗？为什么我不能让这些失败？

RSpec.describe 'Posts', type: :request do
  describe 'ping' do
      it 'returns status 200' do # This text block works correctly.
        get "/api/ping"
        expect(response.content_type).to eq("application/json; charset=utf-8")
        expect(response).to have_http_status(200)
      end
  end

  describe 'get /api/posts' do # all tests below always pass, no matter what.
    it 'should return an error json if no tag is given' do
      get "/api/posts" 
      expect(response.content_type).to eq("application/json; charset=utf-8")
      expect(response.body).to eq("{\"error\":\"The tag parameter is required\"}")
    end

    it 'should return a json of posts' do
      get "/api/posts?tags=tech" do
        expect(body_as_json.keys).to match_array(["id", "authorid", "likes", "popularity", "reads", "tags"])
      end
    end

    it 'should sort the posts by id, in ascending order when no sort order is specified' do
      get "/api/posts?tags=tech" do
        expect(JSON.parse(response.body['posts'][0]['id'].value)).to_be(1)
        expect(JSON.parse(response.body['posts'][-1]['id'].value)).to_be(99)
      end
    end

    it 'should sort the posts by id, in descending order when a descending order is specified' do
      get "/api/posts?tags=tech&direction=desc" do
        expect(JSON.parse(response.body['posts'][0]['id'].value)).to_be(99)
        expect(JSON.parse(response.body['posts'][-1]['id'].value)).to_be(1)
      end
    end
end

在get块的'如果没有给出标签的情况下应该返回一个错误的json'的do块中，我什至尝试了Expect（4）。到eq（5）甚至通过了！

在这里非常感谢您的帮助！

'get'不应有do块。这将导致测试始终通过。

所以这个：

 it 'should sort the posts by id, in descending order when a descending order is specified' do
      get "/api/posts?tags=tech&direction=desc" do. # <<< remove this
        expect(JSON.parse(response.body['posts'][0]['id'].value)).to_be(99)
        expect(JSON.parse(response.body['posts'][-1]['id'].value)).to_be(1)
      end # <<< and this from all tests.
    end

应如下所示：

 it 'should sort the posts by id, in descending order when a descending order is specified' do
      get "/api/posts?tags=tech&direction=desc"
      expect(JSON.parse(response.body['posts'][0]['id'].value)).to_be(99)
      expect(JSON.parse(response.body['posts'][-1]['id'].value)).to_be(1)
    end

RSpec HTTP请求测试始终通过
