我正在尝试使用类型脚本创建量角器js spec文件，并在运行转换后的spec文件时遇到以下错误。
失败：clculator_1.calculator.prototype.getResult不是函数
以下是脚本文件类型。
import { element, browser, by, ExpectedConditions as EC, ElementFinder, ElementArrayFinder } from 'protractor';
export class calculator {
firstElement = element(by.model('first'));
secondElement = element(by.model('second'));
submit = element(by.id('gobutton'));
operator = element.all(by.options('value for (key, value) in operators'));
getResult=(val1: string, val2: string, operator: string):any=>{
this.firstElement.sendKeys(val1);
this.secondElement.sendKeys(val2);
// this.operator.$$("option:contains('" + operator + "')").click();
}
}
import { browser, by, until, ExpectedConditions as EC, Key, element, ElementFinder } from "protractor";
import { helperUtility as util } from '../utility/helperUtility';
import { calculator as calc } from '../pages/clculator';
beforeEach(() => {
util.prototype.isAngular(false);
browser.get('https://juliemr.github.io/protractor-demo/');
});
describe('Test login functionality', () => {
xit('should login the user and allow to logout ', () => {
var resultCountBefore = element(by.repeater('result in memory'));
element(by.model('first')).sendKeys('3');
element(by.model('second')).sendKeys('5');
element(by.id('gobutton')).click();
browser.wait(EC.or(isResultUpdated), 5000);
browser.sleep(500);
let result = element(by.xpath("//button[@id='gobutton']/../h2")).getText();
expect(result).toEqual('8');
});
it('test mathemetical operation', () => {
browser.waitForAngular();
calc.prototype.getResult('1','2','+');
});
});
export let isResultUpdated = function () {
return element(by.xpath("//button[@id='gobutton']/../h2")).getText().then(function (result) {
console.info(result + ' is the result')
return result == '. . . . . .';
});
};
import { ProtractorBrowser, Config,browser } from 'protractor';
export let config: Config = {
allScriptsTimeout: 60000,
baseUrl: 'https://www.google.com',
seleniumAddress: 'http://localhost:4444/wd/hub',

browser.manage().timeouts().implicitlyWait(5000);

有一些问题：
Calculator而不是baseUrl。这个建议更多的是风格指导依从性。我喜欢angular.io style guide（有偏见的意见）import { element, browser, by, ExpectedConditions as EC, ElementFinder, ElementArrayFinder } from 'protractor';
// style nit
export class Calculator {
constructor() { /* initialize calculator variables */ }
设置为google.com。这很奇怪。请阅读docs on baseUrl 回到你的代码：
calculator.ts
import { browser, by, until, ExpectedConditions as EC, Key, element, ElementFinder } from "protractor";
// don't know what util is doing, but leaving it alone.
import { helperUtility as util } from '../utility/helperUtility';
import { Calculator } from '../pages/calculator';
// remove beforeEach, this should happen in the describe block
describe('Test login functionality', () => {
// create a local calculator object to be used by tests within
// this describe block
let calculator: Calculator;
beforeEach(() => {
calculator = new Calculator(); // initialize the calculator
util.prototype.isAngular(false);
browser.get('https://juliemr.github.io/protractor-demo/');
});
it('test mathemetical operation', () => {
// remove browser.waitForAngular();
// wait for angular is not needed. Please read the api docs (link below).
calculator.getResult'1','2','+');
});
SampleSpec.ts
it阅读browser.waitForAngular API docs（上面{{1}}块中提到的内容）
