本文将介绍如何通过Protractor测试框架实现自动化检查，确保生产代码中已清除所有console.log调用，避免应用运行时出现不必要的控制台输出。

For any reason, there is an error in your code, maybe something like undefined error. Protractor still has all the test cases passing, but our application has some problem.

Or let's say in production code, we want check whether we have cleaned all of our console.log() code in the console.

To do that we can add an afertEach() block:

  afterEach(function () {
    browser.manage().logs().get('browser').then(function (browserLog) {
      expect(browserLog.length).toEqual(0);
      if (browserLog.length) console.error('log: ' + JSON.stringify(browserLog));
    });
  });

----------------

Code:

var IndexPage = require('./IndexPage');

describe('hello-protractor', function () {

  var page = new IndexPage();

  beforeEach(function() {
      page.get();
  });

  afterEach(function () {
    browser.manage().logs().get('browser').then(function (browserLog) {
      expect(browserLog.length).toEqual(0);
      if (browserLog.length) console.error('log: ' + JSON.stringify(browserLog));
    });
  });

  describe('index', function () {
    it('should display the correct title', function () {
      expect(page.getTitle()).toBe('hello protractor');
    });

    it('should display the message when button clicked', function () {
      page.clickButton();

      expect(page.getMessageText()).toBe('button 1 clicked');
    });
  });
});
