我已经为主题控制器编写了一个api,它将执行所有操作操作,我需要使用Rspec测试该api。对于索引动作,我已经编写了一个用于http状态的测试用例。此外,我需要检查天气索引页面是否正确呈现。用于索引动作的主题Api控制器是这样的:
class Api::V1::TopicsController < ApplicationController
def index
@topics = Topic.all
render json: @topics,status: 200
end
end
用于主题控制器索引操作的Rspec是:
RSpec.describe Api::V1::TopicsController do
describe "GET #index" do
before do
get :index
end
it "returns http success" do
expect(response).to have_http_status(:success)
////expect(response).to render_template(:index)
end
end
end
运行测试时,它会显示我在注释中提到的上述代码行的错误消息。
Api::V1::TopicsController GET #index returns http success
Failure/Error: expect(response).to render_template(:index)
expecting <"index"> but rendering with <[]>
如何解决? 错误:
TypeError: no implicit conversion of String into Integer
0) Api::V1::TopicsController GET #index should return all the topics
Failure/Error: expect(response_body['topics'].length).to eq(2)
TypeError:
no implicit conversion of String into Integer
答案 0 :(得分:0)
您可以测试控制器操作的API响应,仅作为index
操作的参考。
describe TopicsController do
describe "GET 'index' " do
it "should return a successful response" do
get :index, format: :json
expect(response).to be_success
expect(response.status).to eq(200)
end
it "should return all the topics" do
FactoryGirl.create_list(:topic, 2)
get :index, format: :json
expect(assigns[:topics].size).to eq 2
end
end
end
