无法使用量角器运行Angular 2的端到端测试

Question

我使用的是Angular 2和Angular 2的Seed包。我正在尝试运行端到端测试。我遵循了种子页面上列出的步骤。

我的量角器配置如下:

const config = {
  baseUrl: 'http://localhost:6563/',
  specs: [
    './dist/dev/**/*.e2e-spec.js'
  ],
  framework: 'jasmine',
  jasmineNodeOpts: {
    showColors: true,
    isVerbose: false,
    includeStackTrace: false,
  },
  directConnect: true,
  capabilities: {
    browserName: 'chrome'
  },
  onPrepare: function() {
    const SpecReporter = require('jasmine-spec-reporter');
    jasmine.getEnv().addReporter(new SpecReporter({ displayStacktrace: true }));
    browser.ignoreSynchronization = false;
  },
  useAllAngular2AppRoots: true
};
if (process.env.TRAVIS) {
  config.capabilities = {
    browserName: 'firefox'
  };
}
exports.config = config;

我在一个终端上使用npm run webdriver-start启动web驱动程序。我可以看到selenium服务器启动并运行消息:

我可以从chrome到达http://127.0.0.1:4444/wd/hub并创建会话，但当我在另一个终端上运行E2E测试时，我得到以下错误:

node_modulesselenium-webdriverhttpindex.js:365
      onError(new Error(message));

    at acquireSession (C:Users..node_modulesselenium-webdriverlibwebdriver.js:62:22)
    at Function.createSession (C:Users..node_modulesselenium-webdriverlibwebdriver.js:295:12)

有什么建议可以给我指路吗?

Answer 1

这个错误今天早上才开始。我怀疑是昨晚安装的windows更新造成的。在禁用windows防火墙后，我停止收到ECONNREFUSED.

我得到了另一个错误，不得不更新chromedriver到2.24得到量角器运行

Answer 2

我最近也有这个问题，并通过更新量角器和webdriver来修复它，该版本似乎很旧

Answer 3

这个问题是由于angular 2版本(beta版本或RC版本)。如果你正在做的代码在测试版，并将尝试运行代码在RC版本，我们需要改变配置和版本相应。请更新您的标识符和selenium webdriver版本。
