如何在作为Windows服务运行的Jenkins上以无头模式运行Selenium测试（C＃，.NET）

标签： c# firefox jenkins selenium-webdriver headless-browser

我正在尝试设置Jenkins（版本2.117）并使用Selenium在Windows 10中的.NET堆栈上运行自动化测试，Jenkins作为Windows服务运行。

我正在尝试使用支持无头模式的Firefox 56的Firefox网络驱动程序。

机器和软件

  • Windows 10专业版
  • Jenkins 2.117
  • Selenium Webdriver（此问题的最新版本）
  • Firefox 56,32位
  • GeckoDriver v0.16.1
  • Visual Studio 2017 Enterprise

硒测试

[TestClass]
public class SeleniumTest
{
    [TestMethod]
    [TestProperty("Selenium", "Google")]
    public void GoToGoogle()
    {
        var options = new FirefoxOptions();
        options.AddArgument("-headless");
        var driver = new FirefoxDriver(options);

        driver.Navigate().GoToUrl("https://www.google.com");
        StringAssert.Contains(driver.PageSource, "Google");
    }
}

我可以通过Visual Studio进行测试，但在Jenkins构建期间失败。

用于运行测试的命令：

"C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\TestPlatform\vstest.console.exe" C:\Jenkins\workspace\WorkSpaceName\Tests\bin\ContinuousIntegration\Tests.dll /tests:Google /logger:trx

Jenkins构建输出

以下是构建日志的缩写输出：

当浏览到日志输出中提到的URL（http://localhost:58807/session）时，我得到以下回复：

{
  "value": {
    "error": "unknown command",
    "message": "GET /session did not match a known command",
    "stacktrace": "stack backtrace:\n   0:           0x489f6f - <no info>\n   1:           0x48ad59 - <no info>\n   2:           0x43a15d - <no info>\n   3:           0x42ec0f - <no info>\n   4:           0x423c30 - <no info>\n   5:           0x4078fa - <no info>\n   6:           0x6bc939 - <no info>\n   7:           0x415d0d - <no info>\n   8:           0x6b6e43 - <no info>\n   9:     0x7fff56fe8364 - BaseThreadInitThunk"
  }
}

现在上述回复可能是由于浏览器发出GET请求而不是POST。

Jenkins服务属性

我已经为Jenkins服务尝试了几次配置迭代：

默认配置

  1. 使用“本地系统”帐户
  2. 没有与桌面交互

    3. 结果：与上述相同

    调整本地系统帐户

    1. 使用“本地系统”帐户
    2. 允许与桌面交互的服务已标记为

      3. 结果：与上述相同

      使用本地“Jenkins”用户

      结果：在初始化阶段无法找到活动目录BEAN的异常

      使用我的Active Directory用户

      1. 我自己的用户和密码
      2. 我在机器上拥有管理员权限

        3. 结果：与上面的原始问题相同

        在将Jenkins作为Windows服务运行时，如何在Firefox无头模式下运行Selenium测试？

        更新1：看起来我的Firefox版本（v56）或GeckoDriver（v0.16.1）可能存在问题切换到Chrome 66和ChromeDriver 2.38.552522似乎工作正常。

1 个答案:

答案 0 :(得分：0)

我是Selenium的新手，与我的Firefox版本相比，我没有意识到我正在使用的GeckoDriver版本。更新GeckoDriver（现在称为Firefox驱动程序）可以解决该问题。

如果您认为驱动程序正确，请检查浏览器版本。现代浏览器供应商已启用自动更新。要么禁用该功能并遭受未修补的安全漏洞的后果，要么只是定期检查Web驱动程序是否为最新。
