Question

first of all the versions I'm using:

protractor v5.1.2 chromedriver v2.33 node v6.11.4 npm 3.10.10 selenium-webdriver v3.0.1

I'm new to protractor and I'm only trying to run it on the test that is already given natively by protractor. It looks like this

describe('angularjs homepage', function() {
  it('should greet the named user', function() {
    browser.get('http://www.angularjs.org');

    element(by.model('yourName')).sendKeys('Julie');

    var greeting = element(by.binding('yourName'));

    expect(greeting.getText()).toEqual('Hello Julie!');
  });

  describe('todo list', function() {
    var todoList;

    beforeEach(function() {
      browser.get('http://www.angularjs.org');

      todoList = element.all(by.repeater('todo in todoList.todos'));
    });

it('should list todos', function() {
      expect(todoList.count()).toEqual(2);
      expect(todoList.get(1).getText()).toEqual('build an AngularJS app');
    });

    it('should add a todo', function() {
      var addTodo = element(by.model('todoList.todoText'));
      var addButton = element(by.css('[value="add"]'));

  addTodo.sendKeys('write a protractor test');
  addButton.click();

  expect(todoList.count()).toEqual(3);
  expect(todoList.get(2).getText()).toEqual('write a protractor test');
     });
  });
});

This right here is the conf.js

exports.config = {
  directConnect: true,

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'chrome'
  },

  // Framework to use. Jasmine is recommended.
  framework: 'jasmine',

  // Spec patterns are relative to the current working directory when
  // protractor is called.
  specs: ['example_spec.js'],

  // Options to be passed to Jasmine.
  jasmineNodeOpts: {
    defaultTimeoutInterval: 30000
  }
};

When I try to run this it gives me the following error:

Failures:
1) angularjs homepage should greet the named user

3 specs, 1 failure

[11:34:30] I/launcher - 0 instance(s) of WebDriver still running

[11:34:30] I/launcher - overall: 1 failed spec(s)
[11:34:30] E/launcher - Process exited with error code 1

As I said, I didn't write any of this. The code was provided by protractor itself in a folder called example. Now, however, I tried switching the test cases, because I didn't understand why the first one would fail. It looked perfectly right to me. And now here is what is strange. When I put a different test case on top the new one - that is now on top - will fail, but the one that was on top before won't have any problems anymore. I can do this with every single test case, the first case will always fail, but as soon as I move it away from the top, it suddenly works.

I already tried following the link in the error message, but it didn't do anything for me. Also I've updated everything a hundred times, but nothing changed.

Does anyboby know what this is? This is really strange...

你需要告诉Protractor不要等待Angular $ http和$ timeout，就像这样：

旧的弃用方式：

browser.ignoreSynchronization = true;

新的正确方法：

browser.waitForAngularEnabled(false);

这有帮助吗？

Protractor always fails on first test
