Error: Cannot find module ' in Protractor

Question

所以我是量角器的新手，正在尝试使用页面对象进行测试以使代码更易于管理。这方面有一些问题。

下面是我的主要规范文件 'example_spec.js'

describe('angularjs homepage', function() {

  var home_page = require('../home_page.js');

  it('should greet the named user', function() {
    home_page.enterFieldValue('Jack Sparrow');
    var getHomePageText = home_page.getDyanmaicText();
    expect(getHomePageText).toBe('Hello Steve!');
  });
});

下一个文件是名为 'home_page.js'

的页面对象

var home_page = function(){

    //Send in a value.
    this.enterFieldValue = function(value){
        element(by.model('youName')).sendKeys(value);
    };

    this.getDyanmaicText = function(){
      return element(by.binding('yourName')).getText();

    };

};

module.exports = new home_page();

问题是运行这个测试我得到下面的错误。即使在为文件尝试不同的路径时，我也会不断收到错误消息。任何帮助，将不胜感激。

Answer 1

不是问题的直接答案，而是在导入 Page 对象或 Helper 函数时解决 Protractor 中 "require" 问题的一般方法。

我们所做的是 - 一个用于页面对象，另一个用于助手。将其放入您的配置中的 onPrepare()：

// helper require function to import page objects
global.requirePO = function (relativePath) {
    return require(__dirname + '/../po/' + relativePath + '.po');
};

// helper require function to import helpers
global.requireHelper = function (relativePath) {
    return require(__dirname + '/../helpers/' + relativePath + '.js');
};

相应地调整路径 - __dirname 是您的配置所在的位置。提供的函数适用于以下结构：

- e2e
  - config
     protractor.conf.js
  - po
     home_page.js
  - helpers
     helpers.js
  - specs
     example_spec.js

那么，你就可以拥有：

var home_page = requirePO('home_page');

在您的规范文件中。

要使用热键，您需要安装该程序包。从 https://www.npmjs.com/package/protractor-hotkeys 获取。请在下面输入命令

npm install -g protractor-hotkeys

然后在您的 spec.js 中您需要提及模块路径。按照下面的代码。请试用并提供反馈。

//keyeventexample.spec.js
var hotkeys = require('C:/Users/sam/AppData/Roaming/npm/node_modules/protractor-hotkeys'); 
describe('My first test class', function() {
    it('My function', function() {
        browser.driver.get('https://material.angular.io/cdk/text-field/overview');
       //Can send the value directly 
        //hotkeys.trigger('ctrl+a', { targetElement: element(by.id('text')) });
//Or pass it via element
    var txtfield=element(by.className('mat-form-field-autofill-control mat-input-element cdk-textarea-autosize ng-tns-c98-5 cdk-text-field-autofill-monitored'));

    txtfield.sendKeys("Hello 66");
        hotkeys.trigger('ctrl+a', { targetElement: txtfield });
        hotkeys.trigger('ctrl+c', { targetElement: txtfield });

        console.log("key event is fired");
        browser.sleep(5000);
        txtfield.clear();
        hotkeys.trigger('ctrl+v', { targetElement: txtfield });
        browser.sleep(5000);

    });

})
