Selenium webdriver无法启动Firefox 26+

Question

我使用selenium 2.35与之前版本的firefox更新到版本firefox 26.0之前。我的测试以前运行正常，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:

我试图降级firefox的版本，但无法从mozilla网站获得任何以前的版本。

我也尝试了所有的selenium版本2.36,2.37,2.38,2.39，但它们似乎都没有与firefox 26.0兼容。 一旦我尝试用2.36到2.39替换selenium 2.35，代码中就会出现错误。 当我再次使用2.35替换时，这些错误消失了。

任何人都可以帮助我使用Selenium和Firefox的兼容版本吗？

Answer 1

你可以使用2.XX的任何版本的selenium，但只有我们只能使用firefox25或firefox 14.01到17.XX的限制

Answer 2

原因是：

无法在端口7055上连接到主机127.0.0.1

错误是Selenium Server的版本不知道如何使用较新版本的Firefox。 您需要下载支持较新版本Firefox的较新版本的Selenium Server。

请参阅： 无法在GitHub上的端口7055上连接到主机127.0.0.1 。

Answer 3

Firefox 26与selenium 2.39一起使用

<seleniumVersion>2.39.0</seleniumVersion>

Answer 4

使用firefox 25，它在FF25上运行正常
