StdOut 充斥着 'C:\fakepath' 警告整数除法可能要慢得多，如果可能，请尝试使用 uints 通过 C# 使用 Selenium
StdOut is spammed with 'C:\fakepath' warnings integer divides may be much slower, try using uints if possible using Selenium through C#
我正在使用 Selenium Firefox Web 驱动程序。它工作正常，但是当我使用命令行 "dotnet run" 时，命令行上出现了一些我没有解决的警告日志。我该如何解决这个问题？
var options = new FirefoxOptions();
options.AddArguments("--headless");
IWebDriver driver = new FirefoxDriver(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), options);
var link = "ANY LINK";
driver.Navigate().GoToUrl(link);
driver.FindElement(By.ClassName("ANY CLASS NAME")).Click();
driver.Dispose();
由于图像损坏，这里有一些警告 link

...是 StdOut 在 Webrender 启用时被 C:\fakepath 垃圾邮件的结果。
分析
在启用 WebRender 的情况下打开 Firefox 时，如果 stdout 被捕获，则会观察到这些 warning 消息。这些 warning 消息是 shader 在 GPU -> ANGLE 模块中的 WebRender 更改的结果。
我们在以下主题中详细分析和讨论了这个问题：
- Mozilla - Bugzilla：StdOut is spammed with 'C:\fakepath' when Webrender is enabled
- Chromium - 错误：Issue 765576: WARNING:angle_platform_impl.cc(51)
解决了这个问题
解决方案
确保：
- 将 JDK 升级到最近的水平 JDK 8u222。
- 将 Selenium 升级到当前级别 Version 3.141.59。
- 将 GeckoDriver 升级到 GeckoDriver v0.26.0 级别。
- GeckoDriver 出现在所需位置。
- GeckoDriver 拥有非 root 用户的可执行权限。
- 将 Firefox 版本升级到 Firefox v70.0 级别。
- 清理你的项目工作区通过你的IDE和重建你的项目只需要依赖。
- (WindowsOS only) 使用 CCleaner 工具清除执行 OS 之前和之后的所有琐事 测试套件.
- (LinuxOS only) Free Up and Release the Unused/Cached Memory in Ubuntu/Linux Mint 在你的测试套件执行之前和之后。
- 如果您的基础 Web 客户端 版本太旧，则通过 Revo Uninstaller 卸载它并安装最新的 GA 和发布版本的 Web 客户端.
- 系统重启。
- 以非 root 用户身份执行
Test。
- 始终在
tearDown(){} 方法中调用 driver.quit() 以优雅地关闭和销毁 WebDriver 和 Web Client 实例.
