【中文标题】org.openqa.selenium.WebDriverException: disconnected: received Inspector.detached event error during test execution using Selenium and Chromedriver【英文标题】： 【发布时间】：2020-04-09 15:39:17 【问题描述】：我知道 Selenium 是一种自动化测试工具，但我正在尝试将它用于 RPA（与我的工作环境有关）
我已经下载了 java 代码，它完全按照我想要的方式运行。它从 Excel 表中获取数据，将数据转换为 Java 对象，然后将数据输入到 Web 应用程序中。它在前 20-25 个条目中运行良好，然后开始变慢，最终导致应用程序崩溃。我有几千行要输入。
我尝试使用禁用缓存启动 chrome webdriver，但没有解决问题。
这是禁用缓存的代码。
System.setProperty("webdriver.chrome.driver","C:\\\\DRIVERS\\\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability("applicationCacheEnabled", false);
WebDriver webDriver = new ChromeDriver(cap);
WebDriverWait wait = new WebDriverWait(webDriver, 20);
javascriptExecutor js = (JavascriptExecutor) webDriver;
我正在使用 for each 循环来键入数据。

我了解到在测试期间尝试打开 Chrome DevTools 时会发生这种情况，但我的代码根本没有这样做。请指教。
是 chrome 缓存已满的问题吗？如果是这样，我必须每 30 个左右的条目清除一次吗？
【问题讨论】：
请添加错误和您描述的代码。 使用完整的错误堆栈跟踪更新问题。 您的资源可能用完了？尝试在测试开始/结束时调用 System.gc() 添加了超时的代码 @Jonx，谢谢，会尝试并在此处更新 【参考方案1】：只需添加这一行：
chromeOptions.setPageLoadStrategy(PageLoadStrategy.NONE);
这应该可以解决问题。
【讨论】：
【参考方案2】：此错误消息...
org.openqa.selenium.WebDriverException: disconnected: received Inspector.detached event
...暗示 WebDriverException 是由于 Inspector.detached 事件而引发的。
从您的代码试验来看，很明显您使用Thread.sleep(n); 等待元素可点击 / interacable 调用sendKeys() 这不是理想的方式，如：
Thread.sleep() 将当前线程的执行挂起给定的秒数。该参数可以是一个浮点数，以指示更精确的睡眠时间。实际的挂起时间可能少于请求的时间，因为任何捕获的信号都会在执行该信号的捕获例程后终止 sleep()。此外，由于系统中其他活动的调度，暂停时间可能比请求的时间长。
背靠背调用sendKeys() 和Thread.sleep() 可能会模拟发送以下任一内容：
每个都将尝试打开google-chrome-devtools
现在，根据文章DevTools window keeps closing，如果您尝试打开google-chrome-devtools，ChromeDriver 会自动断开连接。
解决方案
完整的证明解决方案是将Thread.sleep() 和ImplicitWait 的所有实例替换为ExplicitWait
其他注意事项
根据DesiredCapabilities 的文档，applicationCacheEnabled 是一种读/写功能，它采用 boolean 值并配置会话是否可以与应用程序缓存交互。 p>
实施
applicationCacheEnabled可以通过以下两种方式进行配置：
DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability("applicationCacheEnabled", false);
或者
DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, false);
因此，您的代码块将是：
System.setProperty("webdriver.chrome.driver","C:\\DRIVERS\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, false);
ChromeOptions opt = new ChromeOptions();
opt.merge(cap);
WebDriver driver = new ChromeDriver(opt);
