我正在学习rails和rsspec。我在rails应用程序上进行了rspec单元测试(请求测试(。但在谷歌上搜索后，我怀疑我的工作是否走对了路。我的代码可以是"；按功能进行单元测试(不是一种方法，网站的功能除外(创建、显示、删除。(轨道应用"？
这是我的请求测试代码。
require 'rails_helper'
RSpec.describe 'Users', type: :request do
let!(:users) { create_list(:user, 10) }
let(:user_id) { users.first.id }
let(:user) { create(:user) }
def send_request_to_store_user(name, mailaddress)
post '/users', params: {
user: {
name: users.first.name,
mailaddress: users.first.mailaddress
}
}
end
def http_status_success_and_body_element_check(body_element)
expect(response).to have_http_status(:success)
expect(response.body).to include(body_element)
end
describe 'GET' do
context 'Get /users test' do
it 'test user list page' do
get '/users'
http_status_success_and_body_element_check('User List')
end
end
context 'Get /users/create test' do
it 'test user create page' do
get '/users/create'
http_status_success_and_body_element_check('create user')
end
end
context 'Get /users/:id/edit' do
it 'test user edit page' do
get "/users/#{user_id}"
http_status_success_and_body_element_check('edit user')
end
end
context 'Get /users/:id' do
it 'test user show page' do
get "/users/#{user_id}"
http_status_success_and_body_element_check('show user')
end
end
end
describe 'POST' do
context 'test store new user' do
it 'test create new user' do
send_request_to_store_user(user.name, user.mailaddress)
expect do
create(:user)
end.to change { User.count }.from(User.count).to(User.count + 1)
end
it 'test redirect after create' do
send_request_to_store_user(user.name, user.mailaddress)
expect(response).to have_http_status(302)
end
end
end
describe 'DELETE' do
it 'test delete user' do
expect do
delete "/users/#{user_id}"
end.to change { User.count }.from(User.count).to(User.count - 1)
expect(response).to have_http_status(302)
end
end
describe 'PUT' do
context 'user update' do
it 'test user information update' do
old_name = users.first.name
new_name = 'new_name'
expect do
put "/users/#{user_id}", params: {
user: {
name: new_name
}
}
end.to change { users.first.reload.name }.from(old_name).to(new_name)
expect(response).to have_http_status(:redirect)
end
end
end
end
这是我在型号上测试的代码
require 'rails_helper'
RSpec.describe User, type: :model do
it 'user must have name and mailaddress' do
user = create(:user)
expect(user).to be_valid
expect(user.name).not_to be_nil
expect(user.mailaddress).not_to be_nil
end
it 'mailaddress must include @' do
# user = FactoryBot.create(:user)
# If rails_helper.rb has config.include FactoryBot::Syntax::Methods,
# Can use shortcut. Don't have to FactoryBot.create
user = create(:user)
# Test pass if email match with regexp
expect(user.mailaddress).to match(/A[w+-.]+@[a-zd-]+(.[a-z]+)*.[a-z]+z/)
end
end
我认为这些测试没有价值(有意义(。
以下是我的理由：
这些测试告诉你什么？Rails路由器正在工作？控制器的响应是否正确？这两者都不是您的测试责任。Rails已经涵盖了这一点。
如果你想知道"；索引页是否呈现"以及"；我可以CRUD用户吗"然后用Capybara编写系统测试，模拟整个流程。这样，您就可以测试整个系统的真实世界交互。
