量角器测试-失败: javascript错误：[$injector:modulerr]

Question

我正在尝试执行量角器测试，但没有成功。我得到下面的错误消息。你知道为什么我会得到这个错误吗？

我已经正确安装了nodejs、npm和protractor。

以下是我的规范文件：

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);
  });
});

下面是我的conf文件：

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['todo-spec.js']
};

当模块由于某种异常而无法加载时，就会出现此错误。上面的错误消息应该提供额外的上下文。

模块加载失败的一个常见原因是，您忘记了在定义的模块中包含该文件，或者该文件无法加载。
