Question

我正在尝试运行以打字稿编写的量角器测试脚本。但是当我这样做时，我得到的是“ ManagedPromise ”。它不显示任何错误，只是返回“ ManagedPromise”

我的打字稿测试：

   //import {describe, it} from "selenium-webdriver/testing";
import {browser, by, element} from "protractor";

describe("For testing purpose", () => {
    it('should pass', () => {
        browser.get("https://angularjs.org");
        element(by.model('todoList.todoText')).sendKeys('write first 
        protractor test');
        element(by.css('[value="add"]')).click();
        let title = browser.getTitle();
        console.log(title);
    });
});

我的conf.js文件：

  import {browser} from "protractor";

  exports.config = {

    directConnect: true,
    capabilities: {
        'browserName': 'chrome'
    },

    framework: 'jasmine2',

    specs: ['./JSfiles/appExample.js'],

    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 9000
        /* getPageTimeout: 3000,
         allScriptsTimeout: 2000*/
    },

    onPreapre: () => {
        browser.driver.manage().window().maximize();
    }
};

我的package.json文件：

    {
  "name": "typescript-dev-project",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "@types/jasminewd2": "^2.0.3",
    "jasmine": "^3.1.0",
    "jasminewd2": "^2.2.0",
    "protractor": "^5.3.2"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

我的tsconfig.json文件：

"compilerOptions": {
/* Basic Options */
"target": "es5",                          
"module": "commonjs",
"esModuleInterop": true,
"strict": true,
"outDir": "./JSfiles",

尝试运行测试时得到的响应：

Gunderson 在评论中说：You are console.logging a promise. You need to resolve it
发生在以下代码段：

let title = browser.getTitle();
console.log(title);

为了解决这个问题，您可以

browser.getTitle().then(function(text) {
  console.log(text);
});

Protractor console log有更深入的解释。

如何通过异步执行：

it('should pass', async() => {
  //other codez here
  let title = await browser.getTitle();
  console.log(title);
}

无法使用打字稿运行量角器测试脚本
