当我们使用域帐户来控制访问时,没有用户名/密码登录屏幕.当前用户的凭据由浏览器自动传递到该站点.

所以对于我的Selenium测试,我需要能够以特定的用户身份运行Internet Explorer.

我发现了一些关于Windows模拟的文章,我可以在测试运行期间切换到我的测试用户(使用http://support.microsoft.com/kb/306158的代码).但是,如果我创建一个InternetExplorerDriver它启动Internet Explorer与我的凭据,而不是测试用户(虽然这个问题和答案表明它应该工作https://sqa.stackexchange.com/questions/2277/using-selenium-webdriver-with-windows-authentication).

我也可以显式地启动Internet Explorer进程作为我的测试用户,但是我看不到将InternetExplorerDriver绑定到已经运行的Internet Explorer进程的方式,所以这可能是一个死胡同.

我的代码,基本上是从上面的MSDN页面下面的.在调试器中,我可以看到WindowsIdentity.GetCurrent().Name在测试的所有步骤中都是“testUser”.
