title: How to run single e2e test with grunt and protractor
body: <p>I'm assuming this is possible and actually pretty simple, but I'm new to both grunt and protractor and I was not able to find the answer online (maybe I used wrong search criteria).</p>
  
  <p>I have the following e2e test in file <code>test/e2e/Recipients.js</code>:</p>
  
  <pre><code>describe('Recipients Tab', function() {
  
      beforeEach(function () {
          browser.get('#/recipients');
      });
  
      it('should have no e-mail list', function () {
          expect(element(by.css('accordion')).isPresent()).toBe(false);
      });
  });
  </code></pre>
  
  <p>Currently, I'm doing this:</p>
  
  <pre><code>grunt e2e
  </code></pre>
  
  <p>My protractor config file:</p>
  
  <pre><code>exports.config = {
      seleniumAddress: 'http://localhost:4444/wd/hub',
      capabilities: {
          'browserName': 'chrome'
      },
      specs: ['../e2e/**/*.js'],
      baseUrl : 'http://localhost:8080/spr',
  
      jasmineNodeOpts: {
          showColors: true // Use colors in the command line report.
      }
  };
  </code></pre>
  
  <p>Of course this runs all my tests, but while I'm developing a specific test, I don't want to run the entire battery of tests. I want to run this one file.</p>
  
  <p>How can I do that? Is there any flag or something?</p>
  
  <p>Thanks</p>
