NameError: 未初始化的常量 Rails::TestTask

Question

我将此代码放在我的 Rakefile 中，以便能够从附加文件夹“test/classes”（不仅仅是来自 test/models、test/controllers 等）运行测试：

# Adding test/classes directory to rake test.
namespace :test do # line 9
  desc "Test tests/classes/* code"
  Rails::TestTask.new(parsers: 'test:prepare') do |t| # line 11
    t.pattern = 'test/classes/**/*_test.rb'
  end
end

Rake::Task['test:run'].enhance ["test:classes"]

当我运行rails test.

但是当我运行时rails db:migrate，我收到此错误：

NameError: uninitialized constant Rails::TestTask
/Users/Developer/project/Rakefile:11:in `block in <top (required)>'
/Users/Developer/project/Rakefile:9:in `<top (required)>'

我该怎么做才能摆脱错误，但仍然能够从
