JavaScript 错误：resource://gre/modules/XULStore.jsm，第 66 行：错误：使用 GeckoDriver Firefox 和 Selenium 找不到配置文件目录错误

Question

即使我为壁虎驱动程序设置了正确的路径，我仍然遇到错误。

主要：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.Test;

public class firstCase {
    @Test
    static void titleControl(){
        System.setProperty("webdriver.gecko.driver", "D:\\Program Exe's\\geckodriver-v0.26.0-win64\\geckodriver.exe");          // Wee need that as Intellij doesn't know where it looks for browser
        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.google.com");
        Assert.assertEquals(driver.getTitle(),"Google");
    }
}

错误：

Answer 1

此错误消息...

JavaScript error: resource://gre/modules/XULStore.jsm, line 66: Error: Can't find profile directory.

...暗示GeckoDriver 启动/产生了一个新的浏览上下文 即Firefox 浏览会话时出现JavaScript 错误。

---

当Selenium 驱动的GeckoDriver 启动Firefox 浏览会话时，可能会有几个JavaScript 相关WARNINGS 和 ERRORS 作为初始化期间 TRACE 级别日志的一部分。您可以放心地忽略这些初始化错误，直到 GeckoDriver 能够成功启动 Firefox 浏览 会话。

结论

当createSession 成功并且检测到W3C 方言时，您可以放心地忽略错误。
