无法 return 在量角器框架中承诺来自从另一个文件调用的 javascript 函数

Failed to return promise in protractor framework from javascript function called from another file

我是量角器和 javascript 的新手。我正在构建一个测试框架,其中每个测试套件都有相应的模块文件和定位器文件。在测试套件文件的测试用例中,通过传递参数调用测试模块。 当我试图嵌套调用的函数时,我得到 "TypeError: Cannot read property 'then' of undefined"。我看到许多关于堆栈溢出的解决方案,其中未返回 promise,但我从被调用函数返回 promise。以下是代码文件。

UserPage.js // Test suit from where modules are called

var d = require("../Data/TestCaseData.js");
var login = require("../Modules/LoginPageModule.js");
var user = require("../Modules/UserPageModule.js");
var userl = require("../Locators/UserPageLocators");

describe('first test suit',function(){

    beforeEach(function(){

           browser.get(d.iManUrl).then(function(){
            browser.manage().window().maximize();
            login.OSPLogin(d.username,d.password);
        })
    });

    it ('Creating user',function(){
        var person = {'Username' : 'u6' , 'Context' : 'novell' , 'Last name' : 'last' , 'Password' : 'n'};

        user.InputData(person).then(function(){
        //some steps
        };

    })


})

以下是模块:

/**
 * UserPageModule.js
 */
var obj = require("../Locators/LoginPageLocators");
var landing = require("../Locators/LandingPageLocators");
var user = require("../Locators/UserPageLocators");

var usercreated = false;

function UserPageModule(){

    this.InputData = function(person){

        this.InputUserPasswordContext(person).then(function(person){

            this.fill =function(data){
                for (var key in data) {
                      console.log(key);
                      element(by.xpath(user.identificationAddValueButtonXpath.replace("Input Field", key))).click();
                      element(by.css(user.identificationValueInputCss)).sendKeys(person [ key ]);
                      element(by.buttonText(user.identificationAcceptValueButtonText)).click();               
                    }
            }
            return new Promise(function(resolve,request){
                 return resolve(this.fill(person));
            })
        });
    }

    /*this.InputData = function(person){
        this.InputUserPasswordContext(person).then(function(person){
            this.InputFields(person);
        });
    }*/


    this.InputUserPasswordContext = function(person){
            return new Promise(function(resolve,reject){
                //Navigating to user page
                element(by.css(landing.userLinkCss)).click();

                //Clicking on add button
                element(by.css(user.createuserButtonCss)).click();

                //Inputting Username
                element(by.css(user.usernameInputCss)).sendKeys(person.Username).then(function(){
                    delete person.Username;
                });

                //Input password
                element(by.css(user.identificationPasswordInputCss)).sendKeys(person.Password);
                element(by.css(user.identificationRetypeInputCss)).sendKeys(person.Password).then(function(){
                    delete person.Password;
                });

                //Inputting context
                element(by.css(user.contextInputCss)).sendKeys(person.Context).then(function(){
                    delete person.Context;
                }).then(function(){
                    resolve(person);
                })
            })                  
    }




}

module.exports = new UserPageModule

现在我感觉到用 java 和 selenium 制作模块化测试框架是多么容易。

您遇到的错误很常见,可能是因为 beforeEach 函数中缺少 return;如果要向其中添加 .then(),则很可能在 browser.get() 之前需要 return。我不太确定,但请尝试以下操作:

beforeEach(function(){
    return browser.get(d.iManUrl).then(function(){
        browser.manage().window().maximize();
        login.OSPLogin(d.username,d.password);
    });
});

您错过了函数 InputData 顶层的 return

this.InputData = function(person){

        return this.InputUserPasswordContext(person).then(function(person){....
