java - WebDriver 使 Chrome 随机崩溃

Question

在使用 Selenium ChromeDriver 在 Google Chrome 中运行我的测试套件时，它经常使浏览器崩溃，并显示消息“哇!Chrome 崩溃了。现在重新启动？”。基本上会导致代码中的不确定行为。

import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

// Set chromeDriver path
System.setProperty("webdriver.chrome.driver", "chromedriver.exe");

ChromeOptions options = new ChromeOptions();

// Force english
options.addArguments("--lang=en");

// Launch chrome
WebDriver driver = new ChromeDriver(options);
... // Click elements, fill text fields, etc.

下面是抛出的异常示例:

Answer 1

我发现的一件事是，如果您在关闭 chromeDriver 完成之前停止测试，假设您正在调试器模式下运行并终止运行，则 chromeDriver 进程仍然存在于您的任务管理器中。这可能会累积并耗尽您的所有资源。当我摆脱所有这些仍然存在的进程时，这个问题就不再发生。
