NameError：未初始化的常量Rails :: TestTask

Question

为了能够从一个额外的文件夹“测试/类”（不只是从测试/模型，测试/控制器等）运行测试，我把这段代码放在我的Rakefile中：

# 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时，此代码完美工作。

但是当我运行rails db:migrate，我得到这个错误：

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

我该怎么办摆脱错误的，但仍然能够从

负载测试文件中插入

require 'rake/testtask' 

进入Rakefile
