Question

使用Angular 5，CLI v1.5，运行e2e测试。我在另一个终端窗口运行服务。当我运行测试时，它打开浏览器，登录，然后开始执行 - 但它总是在大约10秒后给出错误failed to connect, please retry。

我们有一个假的STS登录页面，它不是Angular，所以我已经禁用，然后重新启用Angular。这一切都有效，它会登录并点击，但10秒后会出错。

app.e2e-spec.ts：

import { AppPage } from "./page-objects/app.po";
import { OrderPage } from "./page-objects/order.po";

describe("tslint App", () => {
    let homePage: AppPage;
    let orderPage: OrderPage;

    beforeEach(() => {
        homePage = new AppPage();
        orderPage = new OrderPage();
    });

    it("should navigate around orders", () => {
        homePage.disableAngular();
        homePage.navigateToSTS();
        homePage.selectUser();
        homePage.clickSignIn();
        homePage.enableAngular();
        expect(homePage.getParagraphText()).toEqual("First LAST");
        homePage.clickOrder();
        expect(orderPage.selectHeader()).toEqual("Orders");
        orderDashboardPage.clickCreateOrder();

        [.... etc]
    });
});

protractor.conf.js：

// Protractor configuration file, see link for more information
// https://github.com/angular/protractor/blob/master/lib/config.ts

const { SpecReporter } = require("jasmine-spec-reporter");

exports.config = {
    allScriptsTimeout: 21000,
    specs: ["./js/e2e/**/*.e2e-spec.ts"],
    capabilities: {
        browserName: "chrome"
    },
    useAllAngular2AppRoots: true,
    directConnect: true,
    baseUrl: "http://localhost/",
    framework: "jasmine",
    jasmineNodeOpts: {
        showColors: true,
        defaultTimeoutInterval: 30000,        
        print: function() {}
    },
    onPrepare() {
        require("ts-node").register({
            project: "./js/e2e/tsconfig.e2e.json"
        });
        jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
    },
    debug: true,
    nodeDebug: true,
    troubleshoot: true,
};

终端输出：

尝试运行webdriver-manager update来安装本地chromedriver，然后您不需要在量角器配置中设置 chromeDriver 设置

exports.config = {
  directConnect: true,
  chromeDriver: chromeDriverPath, <--
  specs: [
    'features/*.feature'
  ],
  capabilities: {
    browserName: 'chrome',
    platform: 'ANY',
    chromeOptions: {
      args: ['--test-type']
    }
  }
}

量角器错误：无法连接，请重试
