LoadError:无法加载此类文件-- minitest/reporters

Question

我在测试我的数据库时遇到一个错误。

我有两个模型。当我添加第二个和Active Admin gem时，我开始收到错误。

 bundle exec rake test:models --trace
** Invoke test:models (first_time)
** Invoke test:prepare (first_time)
** Execute test:prepare
** Execute test:models
rake aborted!

Answer 1

尝试在Gemfile中添加以下内容：

gem 'minitest', group: :test
gem 'minitest-reporters', group: :test

这对我很管用。

Answer 2

你有没有试过这个：

在test_helper.rb文件中，添加以下行：

require "minitest/reporters" Minitest::Reporters.use!
