Question

我在eclipse中运行量角器脚本时遇到问题，我的spec.js文件包括：

describe('angularjs homepage todo list', function() {
  it('should add a todo', function() {

    browser.get('https://angularjs.org');

    element(by.model('todoList.todoText')).sendKeys('write first protractor test');
    element(by.css('[value="add"]')).click();

    var todoList = element.all(by.repeater('todo in todoList.todos'));
    expect(todoList.count()).toEqual(3);
    expect(todoList.get(2).getText()).toEqual('write first protractor test');

    // You wrote your first test, cross it off the list
    todoList.get(2).element(by.css('input')).click();
    var completedAmount = element.all(by.css('.done-true'));
    expect(completedAmount.count()).toEqual(2);
  });
});

和conf.js文件包括：

// conf.js
exports.config = {
  framework: 'jasmine',
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['spec.js']
}

当我运行conf.js文件时，chrome浏览器已成功打开但在等待一段时间后，控制台上会显示以下错误：

请建议。

Answer 1

我得到了相同的错误消息，因为我在chromedriver-2.40中使用了过时版本的chrome。 chromedriver-2.40的release notes表示它支持chrome版本66-68。从较旧的版本升级到Chrome 67可以解决我的错误。
