Selenium创建了空白的firefox浏览器窗口，然后不执行任何操作，而不是运行selenium浏览器测试

Question

我遇到问题，在运行自动化测试时，我无法让firefox与selenium同步。当我运行selenium服务器＆amp; firefox phpunit测试，firefox不断超时（显然），因为它无法连接到适当的端口。当我连接自己时，我得到某种码头403错误“禁止代理”，但我真的不知道如何纠正这个问题。

如何调试此问题以确定问题所在？

有关日志和以下错误消息的更多详细信息：

我启动了selenium服务器：

java -jar selenium-server-standalone-2.42.2.jar

然后我将firefox的功能性selenium测试作为www-data用户运行：

sudo -u www-data ../../vendor/bin/phpunit -c refox.xml functional
PHPUnit 3.7.37 by Sebastian Bergmann.

Configuration read from /srv/xxx/protected/tests/firefox.xml

PHP Notice:  Undefined offset: 1 in /srv/xxx/protected/extensions/webdriver-bindings/phpwebdriver/WebDriver.php on line 58

Screenshot file: /srv/xxx/protected/tests/output/test.failed.1413831941.6997.png

现在，据我所知，硒的相关错误是：

当我在google chrome或firefox中手动连接到127.0.0.1:7055时，会出现错误页面：

HTTP ERROR: 403

Forbidden for Proxy

RequestURI=/

Powered by Jetty://

但我可以连接到显示此selenium小部件的http://127.0.0.1:4444/wd/hub/

点击“创建会话”会创建一个空白的firefox页面，就像测试一样。

所以是的，我如何强制firefox测试使用适当的端口，并确保代理端口全部设置为selenium？

Answer 1

似乎Selenium的每个版本仅支持最新的稳定版Firefox。如下所述：

  

每个版本的Selenium仅支持Firefox N，N-1，ESR和＆amp; ESR-1，其中N是Firefox稳定版＆gt;发布时的频道和ESR是当前的ESR版本。这意味着对于Selenium 2.42我们>支持Firefox 31（N / ESR），30（N-1），24（ESR - 1）。我们应该在＆gt;范围内发布2.43版本。一周，将支持32（N），31（N-1 / ESR），24（ESR -1）

您是否厌倦了更新Selenium或尝试使用较旧版本的Firefox？
