RUBY-RSPEC名称错误:你是说?CategorySerializer

Question

早上好。我想了解为什么在测试我的RSPEC(类别控制器(时，它会给出以下错误消息：

An error occurred while loading ./spec/controllers/api/v1/categories_controller_spec.rb.
Failure/Error:
RSpec.describe CategoriesController, type => :controller do
describe "GET index" do
it 'has a 200 status code' do
get :index
expect(response.status).to eq(200)
end
end
end
NameError:
uninitialized constant CategoriesController
Did you mean? CategorySerializer

这是我的Factorybot

FactoryBot.define dofactory：类别do序列(：name(｛|n|"类别#｛n｝"｝终止结束

这是我的规范/controllers/api/v1/categories_controller_spec.rb

require 'rails_helper'
RSpec.describe CategoriesController, type => :controller do
describe "GET index" do
it 'has a 200 status code' do
get :index
expect(response.status).to eq(200)
end
end
end

这是我的rails_helper.rb

require 'spec_helper'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../config/environment', __dir__)
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'rspec/rails'

在我看来，您似乎忘记添加此类的所有模块。尝试更新spec/controllers/api/v1/categories_controller_spec.rb:

require 'rails_helper'
RSpec.describe Api::V1::CategoriesController, type => :controller do
describe "GET index" do
it 'has a 200 status code' do
get :index
expect(response.status).to eq(200)
end
end
end
