org.openqa.selenium.SessionNotCreatedException：无法找到与 Selenium v​​3.14.0 和 GeckoDriver v0.23.0 匹配的一组功能

Question

我的版本是selenium-java-3.14.0和geckodriver-v0.23.0-win64。 我正在使用以下代码。

WebDriver driver;
System.setProperty("webdriver.gecko.driver", "D:\\Try out files\\geckodriver.exe");
driver = new FirefoxDriver();
String baseURL = "http://www.google.com";
driver.get(baseURL);

当我 运行 它时，我收到以下错误消息。

Answer 1

使用 firefox 版本 56 或 61 和 gecko 驱动程序版本 0.21。并添加 firefox 选项使用配置文件。

FirefoxOptions fo = new FirefoxOptions();
fo.setBinary("C:\Users\ChawlaSh\AppData\Local\Mozilla Firefox\firefox.exe");
ProfilesIni profile = new ProfilesIni();
FirefoxProfile myprofile = profile.getProfile("default");
fo.setProfile(myprofile);
driver = new FirefoxDriver(fo);

我希望这一定会有所帮助。

Answer 2

这个错误信息...

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to find a matching set of capabilities

...表示您的程序无法创建新的 Firefox 浏览器 会话..

分析

有如下几个问题：

• file.separator：分隔文件路径组成部分的字符。在 UNIX 上是 /，在 Windows 上是 \。你也需要逃离他们。
• 您的 JDK 版本 是 1.8.0_151 非常 古老.

---

解决方案

• 使用file.separator作为\与另一个\.[=57=转义]
• 将JDK升级到最近的水平JDK 8u191。
• 确保 GeckoDriver-Firefox 映射

• 您的有效代码块将是：

  WebDriver driver;
  System.setProperty("webdriver.gecko.driver", "D:\Try out files\geckodriver.exe");
  driver = new FirefoxDriver();
  String baseURL = "http://www.google.com";
  driver.get(baseURL);
