rspec(1) - summary

没有测试的代码就是耍流氓

1. rspec(1) - summary
2. specs(2) - model
3. specs(3) - controller
4. specs(4) - request
5. specs(5) - mock
6. [specs(6) - mailer]
7. [specs(7) - view]
8. [specs(8) - routing]
9. [specs(9) - helper]
10. [specs(10) - factory-girl]
11. [specs(11) - fake other gems]
12. [specs(12) - sidekiq]
13. [specs(13) - db migration]
14. [specs(14) - timecop]
15. [specs(15) - jenkins]

废话不多说，用代码说话。

1. 新建rails项目(不带测试， 因为rails的默认测试为minitest)

Bundle complete! 15 Gemfile dependencies, 62 gems now installed.
Use \`bundle show [gemname]\` to see where a bundled gem is installed.
run  bundle exec spring binstub --all
\* bin/rake: spring inserted
\* bin/rails: spring inserted

2. 添加测试rspec_rails gem包到Gemfile中的:development和:test group块

group :development, :test do
     gem 'rspec-rails'
end

3. 执行bundle install安装
4. 初始化spec目录

rails generate rspec:install

可以看到输出：

添加了.rspec，spec/spec_helper.rb，spec/rails_helper.rb文件

5. 运行测试

bundle exec rspec  #测试所有的
bundle exec rspec spec/models  #测试models
bundle exec rspec spec/controllers/accounts_controller_spec.rb  #测试AccountsController

结果：
