Rswag似乎是在集成测试中指定API的不错工具。这是我的第一次尝试，但是受制于FactoryBot。这是我所做的：
在rails_helper.rb中，添加了require和load support辅助文件：
require 'rspec/rails'
require 'factory_bot_rails'
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
在spec_helper.rb中，添加了包括支持帮助器的
RSpec.configure do |config|
config.color = true
config.order = :random
config.include RequestHelpers, type: :request
在spec / support文件夹中，一个文件用于FactoryBot，一个文件用于一些助手：
RSpec.configure do |config|
config.include FactoryBot::Syntax::Methods
end
module RequestHelpers
include Rack::Test::Methods
def json
JSON.parse(last_response.body)
end
def get_with_token(path, params={})
header "Authorization", "Bearer #{gen_jwt}"
get path, params
end
def gen_jwt
payload = {email: 'user@test.com'}
token = JWT.encode(payload, Rails.application.config.jwt_secret, 'HS256')
end
end
创建为spec / factories / node.rb的工厂文件
FactoryBot.define do
factory :node, class: Node do
fqdn { "node_single.test.com" }
Platform { "ubuntu" }
IP { "192.168.99.1" }
isDeleted { false }
end
factory :node_list .... # create a list with sequence
然后，通过了以下传统的rspec api测试：
# spec/controllers/api/v1/nodes_controller_spec.rb
RSpec.describe 'nodes', type: :request do
describe 'index' do
context 'pagination' do
before(:each) do
create_list(:node_list, 32)
end
it 'get first page' do
ops = { pageSize: 10, pageNumber: 1 }
get_with_token "/api/v1/nodes", ops
expect(json["meta"]["total-record-number"]).to eq(32)
expect(json["data"].length).to eq(10)
end
end
end
但是当尝试开发rswag测试文件时，它失败了...
require 'swagger_helper'
describe 'Nodes API', type: :request, swagger_doc: 'api/v1/swagger.json' do
TAGS_NODE = Node.freeze
path '/api/v1/nodes' do
get 'Get all servers' do
tags TAGS_NODE
produces 'application/json'
parameter name: :searchString, in: :query, type: :string
parameter name: :searchColumn, in: :query, type: :string
parameter name: :Authorization, in: :header, type: :string
let(:Authorization) { 'Bearer ' + gen_jwt }
let!(:nodes) { create_list(:node_list, 32) }
response '200', 'Servers found' do
let(:searchString) { '' }
let(:searchColumn) { '' }
run_test! do |repsonse|
data = JSON.parse(response.body)
puts data
end
end
end
end
end
它失败，并出现以下错误：
rspec spec/integration/api/v1/nodes_spec.rb
Randomized with seed 18293
F
Failures:
1) Nodes API /api/v1/nodes get Servers found returns a 200 response

跟踪很长，我想对我有用……
在stackoverflow中也进行了一些Google搜索，但是找不到任何线索。 非常感谢您的帮助！

更改为'before'而不是let时发生相同错误，在rswag集成情况下无法在数据库中创建记录，但在模型规格和控制器规格中确实有效...
答案 0 :(得分：0)
第二天，偶然发现是由于以下代码：
TAGS_NODE = Node.freeze
...
tags TAGS_NODE
在删除TAGS_NODE并更改为tags 'Nodes'之后，一切都进行顺利。
但仍然不了解潜在原因...
