Question

当我尝试通过Protractor运行Jasmine测试时，它给我一个错误：

Debugger listening on ws://127.0.0.1:51610/4a264fb5-0c3d-4952-b511-309442659f88

angularTest1.e2e-spec.ts：

import {browser, by, element} from "protractor";

describe('Protractor Demo App', function() {
  var firstNumber = element(by.model('first'));
  var secondNumber = element(by.model('second'));
  var goButton = element(by.id('gobutton'));
  var latestResult = element(by.binding('latest'));
  var history = element.all(by.repeater('result in memory'));

  function add(a, b) {
    firstNumber.sendKeys(a);
    secondNumber.sendKeys(b);
    goButton.click();
  }

  beforeEach(function() {
    browser.get('http://juliemr.github.io/protractor-demo/');
  });

  it('should have a history', function() {
    add(1, 2);
    add(3, 4);

    expect(history.last().getText()).toContain('1 + 2');
    expect(history.first().getText()).toContain('foo'); // This is wrong!
  });
});

protractor.conf.js：

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/angularTest1.e2e-spec.ts'
  ],
  capabilities: {
    'browserName': 'chrome'
  },
  directConnect: false,
  baseUrl: 'https://angular.io/',
  seleniumAddress: 'http://localhost:4444/wd/hub',
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    defaultTimeoutInterval: 30000,
    print: function() {}
  }
};

尝试从8.9.1更新节点 - ＆gt; 8.9.4并得到同样的错误。在8.9.4之后的更新节点之后 - ＆gt; 9.5.0仍然相同。寻找其他类似的主题，但即使在重新安装项目之后也没有发生任何事情。

Nodejs无法直接执行typescript，必须通过在下面执行更多项目来将typecript转换为javascript。

1）在软件包下面安装更多：

@types/node
@types/selenium-webdriver
ts-node
typescript

2）在项目文件夹中创建tsconfig.json，并在其中添加以下内容：

{
  "compileOnSave": false,
  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "outDir": "typeScript",
    "sourceMap": true,
    "allowJs": true,
    "target": "es6",
    "typeRoots": [
      "node_modules/@types"
    ],
    "types": ["node"]
  },
  "exclude": [
    "node_modules",
    "typescript"
  ]
}
