升级到3.9版后，无法启动Selenium IE驱动程序 [英] Can't launch Selenium IE Driver after upgrading to version 3.9
问题描述
从此处，尝试使用IE(版本:11.0.9600.17842，Win8.1)运行任何测试时，出现以下异常.有谁知道如何解决这个问题，还是我应该降级到3.8?
OpenQA.Selenium.WebDriverException:具有空响应的异常 被引发向远程WebDriver服务器发送HTTP请求以用于 URL http://localhost:53379/session .
该异常的状态为 ReceiveFailure，并且消息为:基础连接为 已关闭:接收时发生意外错误. ---->

从 尽管使用IEDriverServer_Win32_3.9.0进行的快速测试不会显示任何错误.
尽管设置了 IEDriverServer_Win32_3.9.0 和 IEDriverServer_x64_3.9.0 ，但从未明确地将其推送/发布
CHANGELOG IEDriverServer.exe 的内容明确提到了以下免责声明:
The "major" and "minor" fields are synchronized to releases of the Selenium
project. Changes in the "build" field indicate interim releases made publicly
available via the project downloads page. Changes in "revision" field indicate
private releases checked into the prebuilts directory of the source tree, but
not made generally available on the downloads page.
此外， CHANGELOG IEDriverServer.exe v3.9.0.1 的a>提到了以下免责声明:
Finally, there is every chance that, despite all efforts to the contrary,
it's possible that there are new regressions introduced by this change.
Multiple test suites have been run using this change, and none have
failed thus far due to the changes herein. Claims that this change is
causing a specific failure should be accompanied by a full test case, or
issues reported against this change will be summarily closed.
解决方案
简单的解决方案是:
- 在32位和64位平台上均使用 IEDriverServer_Win32_3.9.0 .
- 恢复为 IEDriverServer_x64_3.8.0
After updating to IEDriverServer 3.9 for 64-bit from here, I'm getting the following exception when trying to run any tests with IE (version: 11.0.9600.17842, Win8.1). Does anyone know how to get around this, or should I just downgrade back to 3.8?
OpenQA.Selenium.WebDriverException : A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://localhost:53379/session.
The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected error occurred on a receive. ---->

Using IEDriverServer 3.9.0.0 for Windows 64-bit from http://selenium-release.storage.googleapis.com I am able to reproduce the issue with IEDriverServer_x64_3.9.0.

Though a quick test with IEDriverServer_Win32_3.9.0 doesn't shows any error.
Though IEDriverServer_Win32_3.9.0 and IEDriverServer_x64_3.9.0 are put up but was never explicitly pushed/published to be available on the Download tab of seleniumhq.org page.
The CHANGELOG of IEDriverServer.exe clearly mentions the following disclaimer :
The "major" and "minor" fields are synchronized to releases of the Selenium
project. Changes in the "build" field indicate interim releases made publicly
available via the project downloads page. Changes in "revision" field indicate
private releases checked into the prebuilts directory of the source tree, but
not made generally available on the downloads page.
Additionally, the CHANGELOG of IEDriverServer.exe v3.9.0.1 mentions the following disclaimer :
Finally, there is every chance that, despite all efforts to the contrary,
it's possible that there are new regressions introduced by this change.
Multiple test suites have been run using this change, and none have
failed thus far due to the changes herein. Claims that this change is
causing a specific failure should be accompanied by a full test case, or
issues reported against this change will be summarily closed.
Solution
The simple solution would be either to :
- Use IEDriverServer_Win32_3.9.0 on both 32bit and 64-bit platforms.
- Revert back to IEDriverServer_x64_3.8.0
