haskell - 如何让 WebDriver 在 Haskell 的 Mac 上工作？

所以(在我不断尝试成为 Haskell 程序员的过程中)我想我会尝试使用 Haskell 来自动控制 Mac 上的 Firefox。前往https://github.com/kallisti-dev/hs-webdriver ，安装 webdriver，安装独立的 java selenium 服务器并尝试运行简单的 Hello World 测试(修复语法错误后，runSession 的 'config' 参数应该是(我假设)'myConfig')

看起来 Firefox 打开了一会儿，然后消失了。基于 Java 的 selenium 服务器产生了大量的错误消息。见下文。

有谁知道怎么了？

值得一提的是，在尝试了这个之后，我安装了 python 绑定(bind)并在大约 10 秒内完成了一个 python 版本!

最佳答案

好的，看来图书馆大约一年没有更新了，但这里是我的建议:

  • 使用homebrew安装 selenium-standalone-server 和 chromedriver。然后使用配置选择standard Chrome configuration .
  • 请注意，该库的 0.6.1 版本落后于当前的 master，该 master 具有重要的修复以与最新的 selenium-server-standalone 一起使用。你会发现它几乎是兼容的，但我遇到了一个问题:https://github.com/kallisti-dev/hs-webdriver/issues/60

    • 从那里您应该能够启动并运行测试。我知道它已在我的机器上成功运行。如果您对这种方法有更多疑问，请询问。
