无涯教程-RSpec - Tags标签

RSpec Tags提供了一种在规范文件中运行特定测试的简便方法。假设您只想运行指定测试方法，则可以使用Tags标签实现。

describe "How to run specific Examples with Tags" do 
   it 'is a slow test', :slow=> true do 
      sleep 10 
      puts 'This test is slow!' 
   end 
   
   it 'is a fast test', :fast=> true do 
      puts 'This test is fast!' 
   end 
end

现在，将上面的代码保存在一个名为tag_spec.rb的新文件中。在命令行中，运行以下命令: rspec --tag slow tag_spec.rb

您将看到此输出-

This test is slow! 
. 
Finished in 10 seconds (files took 0.11601 seconds to load) 
1 example, 0 failures

然后，运行以下命令:rspec --tag fast tag_spec.rb

Run options: include {:fast=>true} 
This test is fast! 
. 
Finished in 0.001 seconds (files took 0.11201 seconds to load) 
1 example, 0 failures

如您所见，RSpec标签使子集测试非常容易!
