Rails测试正常，但在使用后卫运行时，它们会失败

标签： ruby-on-rails ruby minitest guard

我在这里创建了一个带有问题的示例应用程序 https://github.com/jean-francois-labbe/rails-guard-not-working

这只是一个带有rails 5.1.4和ruby 2.4.2的简单脚手架 rails g scaffold user username firstname creation:datetime rails db:migrate bundle exec rails test # => tests ok bundle exec guard # => 3 tests will fail

我在Gemfile中添加了guard和guard-minitest。

有没有人遇到过这个问题？

测试以下结果： 

~/Workspace/guard-tests-fail(master ✗) bundle exec rails test

使用与rails测试相同的种子保护

重现的步骤

1）创建一个新项目（rails new demo）

2）生成一个脚手架（rails g scaffold用户名）

3）rails test =＆gt;导轨测试没问题

4）在Gemfile中添加gem'guard'和gem'guard-minitest'。并运行bundle

5）运行警卫init minitest。

6）捆绑exec guard =＆gt;而且你的测试会很糟糕

这是guard-minitest和spring的问题。前往Guardfile并将此spring命令配置添加到初始化：

# Guardfile

guard "minitest", spring: "bin/rails test" do
  # ...
end

有一些半相关的讨论here。 guard-minitest自述文件说这是＆＃34;由于处理参数的复杂性以及对所选文件的运行测试＆＃34;。
