使用jasmine在量角器中使用javascript原型（继承）概念

大家好，我正在尝试使用POM概念，我的代码是第一个文件basefile.JS

var basefile = function() {
};
basefile.prototype.elementClick = function(locator) {
 element(by.xpath(locator)).click();
};
//module.exports = new basefile();

require("./basefile.js");

var tempPageOne = function(){

 var BaseMethod = new basefile();
 this.ddselection = function(locOne,locTwo){
  BaseMethod.elementClick(locOne);
  BaseMethod.elementClick(locTwo);
 };
};
module.exports = new tempPageOne();

describe("sample to check inheritance",function(){
 var testOne = require("./tempPageOne.js");

 it("working with inheritance",function(){
  browser.get("http://www.protractortest.org/#/");
  testOne.ddselection("html/body/nav/div/div[2]/div/ul/li[3]/a","html/body/nav/div/div[2]/div/ul/li[3]/ul/li[4]/a");
  console.log("Working fine");
 });

});

此文件包含用户可以在任何web应用程序上执行的常用方法。 第二个js文件tempPageOne.js我的代码是

var basefile = function() {
};
basefile.prototype.elementClick = function(locator) {
 element(by.xpath(locator)).click();
};
//module.exports = new basefile();

require("./basefile.js");

var tempPageOne = function(){

 var BaseMethod = new basefile();
 this.ddselection = function(locOne,locTwo){
  BaseMethod.elementClick(locOne);
  BaseMethod.elementClick(locTwo);
 };
};
module.exports = new tempPageOne();

describe("sample to check inheritance",function(){
 var testOne = require("./tempPageOne.js");

 it("working with inheritance",function(){
  browser.get("http://www.protractortest.org/#/");
  testOne.ddselection("html/body/nav/div/div[2]/div/ul/li[3]/a","html/body/nav/div/div[2]/div/ul/li[3]/ul/li[4]/a");
  console.log("Working fine");
 });

});

在这里，我调用我的basefile.JS并使用thirdd JS文件testMethod.JS中定义的方法，我的代码是

var basefile = function() {
};
basefile.prototype.elementClick = function(locator) {
 element(by.xpath(locator)).click();
};
//module.exports = new basefile();

require("./basefile.js");

var tempPageOne = function(){

 var BaseMethod = new basefile();
 this.ddselection = function(locOne,locTwo){
  BaseMethod.elementClick(locOne);
  BaseMethod.elementClick(locTwo);
 };
};
module.exports = new tempPageOne();

describe("sample to check inheritance",function(){
 var testOne = require("./tempPageOne.js");

 it("working with inheritance",function(){
  browser.get("http://www.protractortest.org/#/");
  testOne.ddselection("html/body/nav/div/div[2]/div/ul/li[3]/a","html/body/nav/div/div[2]/div/ul/li[3]/ul/li[4]/a");
  console.log("Working fine");
 });

});

这是我的规范文件，用于一个简单的测试，但遇到错误时不知道该怎么办 失败： 1） 检查继承的示例遇到声明异常 信息： ReferenceError:未定义基本文件 堆栈： ReferenceError:未定义基本文件 在新的tempPageOne上（D:\eclipseProject\JavaScriptInheritation\tempPageOne.js:4:23） 反对。（D:\eclipseProject\JavaScriptInheritation\tempPageOne.js:10:18） 根据需要（module.js:385:17） 在套房。（D:\eclipseProject\JavaScriptInheritation\testMethod.js:3:16）

您还可以扩展basefile以便

var basefile = function() {
};

basefile.prototype.elementClick = function(locator) {
  element(by.xpath(locator)).click();
};  
module.exports = new basefile();

然后

var basefile = require("./basefile.js");

var tempPageOne = function(){
  this.ddselection = function(locOne,locTwo){
    this.elementClick(locOne);
    this.elementClick(locTwo);
  };
};
tempPageOne.prototype = basefile; // extend basefile
module.exports = new tempPageOne();

---

保持所有内容不变在任何Js文件中都不做任何更改，只需像这样更改tempPageOne.Js，即可正常工作

   var basefile = require("./basefile.js");

var tempPageOne = function(){

/*  // Comination One : works this way also
    var BaseMethod = Object.create(basefile);
    this.ddselection = function(locOne,locTwo){
        BaseMethod.elementClick(locOne);
        BaseMethod.elementClick(locTwo);
    };*/


    /*
    // Comination Two :works this way also
    var BaseMethod = basefile;
    this.ddselection = function(locOne,locTwo){
        BaseMethod.elementClick(locOne);
        BaseMethod.elementClick(locTwo);
    };
    */

    // Comination Three :works this way also
    //var BaseMethod = basefile;
    this.ddselection = function(locOne,locTwo){
        basefile.elementClick(locOne);
        basefile.elementClick(locTwo);
    };

};

module.exports = new tempPageOne();
