继this问题，我试过（naievely）要做到这一点：

量角器测试/功能/量角器-conf.js --params.test_set = dev_test

和

量角器-conf.js：

  exports.config = {   // ...  规格：[browser.params.test_set +'/ *功能']， 

...但当然，因为浏览器是不是在那个conf文件是解析时定义这是行不通的。

所以，我怎么能实现这样的效果：将参数传递到量角器确定的规格

使用 - 规格命令行参数：

- 规格文件，以测试的逗号分隔列表

 量角器测试/功能/量角器-conf.js --specs = dev_test / *功能 

注意 dev_test / *功能将传递到量角器的命令行界面，将根据当前的工作目录（的来源$ C ​​$ C ）。

Following the lead of this question, I tried (naievely) to do this:

protractor test/features/protractor-conf.js --params.test_set=dev_test

and

protractor-conf.js:

exports.config = {
   // ...
  specs: [browser.params.test_set+'/*.feature'],

... but of course it doesn't work because browser is not defined at the time that the conf file is parse.

So how could I achieve this effect: passing a parameter to protractor that determines the specs?

Use the --specs command-line argument:

--specs Comma-separated list of files to test

protractor test/features/protractor-conf.js --specs=dev_test/*.feature

Note that dev_test/*.feature would be passed into the protractor's command-line-interface which would resolve the paths based on the current working directory (source code).
