Selenium webdriver 无法使用 Firefox 26+ 启动

Question

在更新到版本 Firefox 26.0 之前，我使用 selenium 2.35 和以前版本的 firefox。我的测试之前运行良好，但现在我最终收到以下错误。

 org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

我尝试降级 firefox 的版本，但无法从 mozilla 站点获取任何以前的版本。

我还尝试了所有 selenium 版本 2.36、2.37、2.38、2.39，但似乎没有一个与 firefox 26.0 兼容。一旦我尝试将 selenium 2.35 替换为 2.36 到 2.39，代码中就会出现错误。当我再次用 2.35 替换时，这些错误就会消失。

谁能帮我解决 Selenium 和 Firefox 的兼容版本？

Answer 1

原因：

无法在端口 7055 上连接到主机 127.0.0.1

错误是 Selenium Server 的版本不知道如何与较新版本的 Firefox 一起工作。您需要下载支持较新版本 Firefox 的较新版本的 Selenium Server。

请参阅：Unable to connect to host 127.0.0.1 on port 7055 at GitHub。

Answer 2

Firefox 26 与 selenium 2.39 配合使用

<seleniumVersion>2.39.0</seleniumVersion>

Answer 3

您可以使用从 2.XX 开始的任何版本的 selenium，但唯一的限制是我们只能使用 firefox25 或 firefox 14.01 到 17.XX

Answer 4

使用 firefox 25 ，在 FF25 上运行良好
