object不是构造函数Protractor Javascript

Posted 2021-04-19

我一直收到这条消息说Newpage不是构造函数我在过去的5个小时里绞尽脑汁试图解决这个问题并没有进展我看了下面的网站How to call a function in another function in protractor

'TypeError: undefined is not a function' using Protractor也许这是我不知道的简单事情。我所要做的就是从我的页面对象文件中调用一个函数。仍然没有成功任何帮助将不胜感激。

我的代码：

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

describe('Get Payroll Information', function() {

  beforeAll(function(){
        var newPageObj = new newPage();
    });

          var EC = protractor.ExpectedConditions;
          var status;
          var clientid, weeknum, pdate;


it('Get CycleStatus, Paydate, Weeknumber, Clientid - completed', function () {
              const fs = require('fs');
              const cycle = $('#cycleStatusID'); // cycle status
              const client = $('#clientID'); // clientid
              const week = $('#companyIdBar_weekId'); // week number
              const payDate = $('#companyIdBar_processDateId');


                //------------Get PayDate --------------------------------
                              .then(() => {
                              payDate.isPresent().then(function(present){
                                if(present){
                                       payDate.getText().then(function(text){
                                         pDate = text;
                                        console.log('paydate (' + pDate + ') is displayed');
                                      });
                                          } else {
                                            console.log('pay date not present');
                                            //return;// breaks for loop like (break)
                                        }
                                      })
                                    })
                                  .then(() => {
                                      writeValueToFile(cycleStatus,clientID,weekNum,pDate);
                                  })
                                  .then(() => {
                                      newPageObj.goBack();
                                      console.log('return to support');
                                  });


                    });// master then promise

              });//spec function

量角器控制台消息

newPage.js代码：

newPage = function(){
    function goBack(){
      var returnbtn = $('#returnToADPClick');
      var search1 = ($$('input[id="toolbarQuickSearch"]').get(0));
      returnbtn.click();
      browser.wait(EC.elementToBeClickable(search1),20,000);
};
};
module.exports = new newPage();

更改为module.exports = new newPage; //这项工作现在我得到

答案

你的newPage.js正在输出一个物体，而不是function/class/constructor。像这样将module.exports更改为newPage：

newPage = function(){
    function goBack(){
      var returnbtn = $('#returnToADPClick');
      var search1 = ($$('input[id="toolbarQuickSearch"]').get(0));
      returnbtn.click();
      browser.wait(EC.elementToBeClickable(search1),20,000);
};
};
module.exports = newPage;

另一答案

Failed: newPageObj Object not defined

这是因为newPageObj变量的范围 - 目前它仅在beforeAll的范围内定义。在更高级别声明您的变量：

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

var newPageObj;

describe('Get Payroll Information', function() {
    beforeAll(function() {
        newPageObj = new newPage();
    });

    // ...
});
