NameError：未初始化的常量Rails :: TestTask

Question

爲了能夠從一個額外的文件夾「測試/類」（不只是從測試/模型，測試/控制器等）運行測試，我把這段代碼放在我的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"] 

當我運行rails test時，此代碼完美工作。

但是當我運行rails db:migrate，我得到這個錯誤：

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

我該怎麼辦擺脫錯誤的，但仍然能夠從

Answer 1

負載測試文件中插入

require 'rake/testtask' 

進入Rakefile
