Selenium 创建空白的 firefox 浏览器窗口，然后它什么都不做，而不是运行 selenium 浏览器测试

Question

在运行自动化测试时，我遇到了无法让 firefox 与 selenium 同步的问题。当我运行 selenium 服务器和 firefox phpunit 测试时，firefox 不断超时（显然），因为它无法连接到适当的端口。当我自己连接时，我收到某种码头 403 错误“禁止代理”，但我真的不知道如何解决这个问题。

如何调试它以确定问题出在哪里？

有关日志和错误消息的更多详细信息如下：

我启动 selenium 服务器：

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

然后我以 www-data 用户身份运行 firefox 的功能硒测试：

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
FCurrent URL: (Unknown)
Current Title: (Unknown)
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，它会得到错误页面：

HTTP ERROR: 403

Forbidden for Proxy

RequestURI=/

Powered by Jetty://

但我可以连接到显示这个 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。

是的，我如何强制 firefox 测试使用适当的端口，并确保该代理端口已全部设置为 selenium？

Answer 1

似乎每个版本的 Selenium 都只支持最新的稳定版 Firefox。如下所述：

每个 Selenium 版本仅支持 Firefox N、N-1、ESR 和 ESR-1，其中 N 是发布时的 Firefox stable > 频道，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 > 周内发布 2.43 版本，它将支持 32 (N)、31 (N-1/ESR)、24 (ESR -1)

您是否厌倦了更新 Selenium 或尝试使用旧版本的 Firefox？
