【问题标题】:Error: Cannot find module 'jasmine-expect' [Protractor]错误:找不到模块 'jasmine-expect' [量角器]
【发布时间】:2016-09-04 08:58:18
【问题描述】:

我正在尝试运行一个简单地连接到我的应用程序的量角器测试。

当我运行时(git bash/终端):

   protractor conf.js

我收到以下错误:“

错误:找不到模块'jasmine-expect'

看到这个后,我继续安装模块:

npm install -g jasmine-expect

但我仍然收到同样的失败。

这是我的测试:

describe('DragAndDrop Test', function () {
require('protractor');
require('jasmine-expect');


beforeAll(function () {
    context = new Context();
    context.get();
    browser.waitForAngular();
    browser.driver.manage().window().maximize();
});

it('should drag and drop Application Experience tile', function () {

    //target is where we are dragging the box to.  Box is the Box
    var target = { x: 300, y: 50 };
    var box = element(by.cssContainingText('h3', 'Application Experience'));

    //scope is going to hold the scope variables that tell us where the box is located
    //get the standardItems Scope

    box.evaluate('dashboards').then(function(scope) {
        //make sure the box we are using is initially set in column 0 and Row 0
        expect(scope['1'].widgets[0].col).toEqual(0);
        expect(scope['1'].widgets[0].row).toEqual(0);
    });

    //drag and drop the box somewhere else.
    browser.actions().dragAndDrop(box, target).perform();
    browser.waitForAngular();
    browser.driver.sleep(5000);

    //get the updated scope
    box.evaluate('dashboards').then(function(scope) {
        //test to see that the box was actually moved to column 1 and row 0
        expect(scope['1'].widgets[0].col).toEqual(1);
        expect(scope['1'].widgets[0].row).toEqual(0);
    });
});

});

var Context = function () {
this.ignoreSynchronization = true;
    //load the website
    this.get = function () {
        browser.get('http://127.0.0.1:62734/index.html#/dashboard');
    };
};

这是我的 conf.js:

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['gridster-Test.js'],
    capabilities: {
    browserName: 'firefox'
   }
};

有什么建议吗?

    【解决方案1】:

    确保将依赖项添加到您的 package.json 文件中。

    npm install jasmine-expect --save-dev 
    

    【讨论】:

      【解决方案2】:

      首先,尝试在不使用-g 标志的情况下安装软件包:

      npm install jasmine-expect
      

      另外,将require('jasmine-expect');describe 下移动到Protractor 配置文件中的onPrepare()

      onPrepare: function () {
          require("jasmine-expect");
      },
      

      【讨论】:

      • 除了您建议的 onPrepare() 之外,尝试在没有 -g 标志的情况下进行安装。相同的错误信息。它找不到茉莉花期望。它安装成功,所以我不知道发生了什么。
