失败：this.runnable 不是函数

Question

当我尝试运行我的量角器测试时，浏览器 window 启动并在几秒钟后关闭，上面没有任何 activity。控制台显示错误

1) Mail suite Send email
  - Failed: this.runnable is not a function
  - Failed: this.runnable is not a function

Executed 1 of 1 spec (1 FAILED) in 0.074 sec.
[08:01:26] I/launcher - 0 instance(s) of WebDriver still running
[08:01:26] I/launcher - chrome #01 failed 1 test(s)
[08:01:26] I/launcher - overall: 1 failed spec(s)

npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the protractor-example@1.0.0 e2e script.
npm ERR! This is probably not a problem with npm. There is likely additional 
logging output above.

这是我的"spec.ts"

import {LoginPage} from '../page-objects/pages/login/login.po';
import {LoginPageHelper} from '../page-objects/pages/login/login-page.helper';
import {browser, By, element, ExpectedConditions} from 'protractor';
import {beforeEach, describe, it} from 'selenium-webdriver/testing';

describe('Mail suite', () => {
let loginPageHelper: LoginPageHelper;

beforeEach(() => {
    loginPageHelper = new LoginPageHelper();
});

it('Send email', async () => {
    const user1 = browser.params.user1;
    await loginPageHelper.goToPage();
    await LoginPage.username.sendKeys(user1.username);
    await element(By.id('identifierNext')).click();
    await browser.wait(ExpectedConditions.visibilityOf(LoginPage.password));
    await LoginPage.password.sendKeys(user1.password);
});
});

请帮我调试这个错误。提前致谢

Answer 1

中定义的内容

protractor.conf.js

函数this.runnable？也许你想定义它

var runnable

而不是

this.runnable

Answer 2

啊，我终于明白了。正是我的 "spec.js" 中的这一行导致了上述错误

import {beforeEach, describe, it} from 'selenium-webdriver/testing';

我一用beforeEach，webstorm就警告了。当我尝试使用 webstorm 的自动建议时，它要求做 "Alt+Enter"。它自动导入了这一行。

删除此行已解决问题。
