javascript - BrowserStack - Node.js 并发测试

Question

我一直在寻找方法，专门使用 BrowserStack 在 Node.js 中创建合理的可扩展测试结构。

请在此处查看源代码:

https://gist.github.com/Palgie/10886008

我在尝试关闭 session 或退出驱动程序时遇到问题，因此在运行并发测试时它会经常告诉我我的最大 session 正在使用中(见下文)。

这感觉像是一种竞争条件，但它可能非常明显。

  Now testing Chrome - 22.0
  Now testing IE - 10.0
  ․․․․
  Stopping test
  Stopping test
  ․

    4 passing (14s)
    1 failing

    1)  "after all" hook:
       Error: This driver instance does not have a valid session ID (did you call WebDriver.quit()?) and may no longer be used.

        at Timer.listOnTimeout [as ontimeout] (timers.js:110:15)

在我引用的源代码中，据我所知它应该执行 session ，但感觉不像它。

test.after(function() {
  console.log('Stopping test');
  driver.quit();
});

据我所知，在该浏览器中运行所有 mocha 测试或 webdriver 测试后，它将终止驱动程序，然后在 before 方法中初始化一个新实例。

如有任何帮助，我们将不胜感激!

干杯

Answer 1

您可以使用 selenium-runner 并行运行测试。以下文档中提供了使用 selenium-runner 在 BrowserStack 上并行运行测试的示例:https://www.browserstack.com/automate/node .

此外，如果 selenium-runner 不能满足您的需求，能否请您分享您的需求(您想并行运行哪个特定框架或库代码)以便我们研究问题
