Using multiple membership providers for testing

I would like to add another membership provider in my webconfig.   what I need to do is look at a Boolean true or false and change the system that they log into.  This is for testing purposes.  So they log into a membership database that is located on another server.  Any ideas how to handle this in vb code dealing with login request and create request as well as the roles.  Here is what I have tried.

   Dim myProvider As SqlMembershipProvider

        If mTestMode = False Then
            myProvider = Membership.Providers("DefaultMembershipProvider")

            myProvider = Membership.Providers("DefaultMembershipProviderDemo")

        End If

        If myProvider.ValidateUser(mUserName, mPassword) Then

In web.config, configure multiple memberships:

<membership defaultProvider="Server1Provider">
<providers >
<add connectionStringName="DBConnectionStr"
<add connectionStringName="DBConnectionStr2"
name="Server2Provider" type="System.Web.Security.SqlMembershipProvider"/>

In code you can choose:

Dim myProvider As MembershipProvider

If mTestMode = False Then
            myProvider = Membership.Providers.Item("Server1Provider")

            myProvider = Membership.Providers.Item("Server2Provider")

        End If

        If myProvider.ValidateUser(mUserName, mPassword) Then
