错误：找不到模块 'jasmine-expect' [Protractor]

Question

我试图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（git bash/终端）时：

   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？

Answer 1

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，移动require('jasmine-expect'); 从describe进入量角器配置文件中的onPrepare() ：

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

Answer 2

确保将依赖项添加到您的 package.json 文件中。

npm install jasmine-expect --save-dev
