ruby on rails测试

Rspec测试

Rspec(基本测试)

安装

    group :development, :test do      gem 'rspec-rails', '~> 3.5'    end    rails generate rspec:install

重要操作

• 文件: spec/rails_helper.rb
• 去掉注释(23行):...spec/support/**/*.rb..

第一个测试

• 生成模型

    rails g model book name author price 

• spec/models/book_spec.rb

    require 'rails_helper'    RSpec.describe Book, type: :model do      it "数据正确可以通过测试" do        book = Book.new(              name: 'xx',              author: 'yy',              price: 123        )        expect(book).to be_valid      end    end

运行测试

bundle exec rspec

guard-rspec(测试自动)

安装

group :development, :test do  gem 'guard-rspec', '~> 4.7'endbundle exec guard init rspecbundle exec guard

shoulda-matchers（简化测试）

安装

group :development, :test do  gem 'shoulda-matchers', '~> 3.1'end

新增文件spec/support/shoulda_matchers.rb

# https://github.com/thoughtbot/shoulda-matchers#getting-startedRSpec.configure do |config|  Shoulda::Matchers.configure do |config|    config.integrate do |with|      # test framework      with.test_framework :rspec      # libraries      with.library :rails    end  endend

结果显示格式(.rspec)

选择一个模式即可

文档模式

    --format documentation

fuubar模式

gem 'fuubar', '~> 2.2'--format Fuubar
