asp.net-mvc – 如何运行Internet Explorer Selenium测试作为一个特定的域用户？

我有一个ASP.NET MVC网站使用 Windows身份验证来控制访问.我想要有一个specflow selenium测试,通过尝试作为非授权用户访问该站点来检查配置是否正确.

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”.

解决方法

>在后台使用其他用户凭据手动启动浏览器驱动

Process driverProcess;
string driverPath; // The path to Selenium's IE driver.
ProcessStartInfo info = new ProcessStartInfo(driverPath)
{
    UserName = "UserName",// The user name.
    Password = new SecureString(),// The password for the user.
    UseShellExecute = false,LoadUserProfile = true,Arguments = "about:blank"
};
// Start the driver in background thread
Thread startThread = new Thread(
    () => {
        try
        {
            driverProcess = Process.Start(info);
            driverProcess.WaitForExit();
        }
        catch
        {
            // Close the process.
        }
    })
{
    IsBackground = true
};
startThread.Start();

>使用远程Web驱动程序来连接手动启动的浏览器驱动程序实例.

var remoteDriver = new RemoteWebDriver(Uri("http://localhost:5555"),DesiredCapabilities.InternetExplorer());

>记住在完成后关闭/退出/终止驱动程序进程和浏览器实例.

// Close the process when done.
if (driverProcess != null)
{
    // Free managed resources
    if (!driverProcess.HasExited)
    {
        driverProcess.CloseMainWindow();
        driverProcess.WaitForExit(5000);
        // Kill the process if the process still alive after the wait
        if (!driverProcess.HasExited)
        {
            driverProcess.Kill();
        }

        driverProcess.Close();
    }

    driverProcess.Dispose();
    driverProcess = null;
}
