title: Browser automatically closed before test run in Protractor
body: <p>I'm new to Protractor. I'm writing a script to test my web site. But, Browser opens and closes. I couldn't even get to see what happens. Can someone tell me what to do?</p>
  
  <p>This is my configuration.js</p>
  
  <pre><code>  exports.config = {
        seleniumAddress: 'http://localhost:4444/wd/hub',
        specs: ['HomePageObjectSpec.js'],
        onPrepare: function () {  
           browser.driver.manage().window().setSize(1680, 1050);
        },
     }
  </code></pre>
  
  <p>Here is my test.js</p>
  
  <pre><code>describe('Protractor Demo App', function() {
    it('should have a title', function() {
      browser.get('my url');
  
      element(by.css('.btn')).click();
    });
  });
  </code></pre>
