Unit Testing a Membership Provider Implementation...

[Guest]

I recently developed a membership provider and wondered how to unit test it
with NUnit. I came up with this simple solution. I do not try to update
config files at runtime and thus I have only used this for reading settings
(no writing).

public static MyMembershipProvider GenerateProvider( )
{
MyMembershipProvider mp = new MyMembershipProvider( );

//Try the web.config file first...
string path = HostingEnvironment.ApplicationVirtualPath;

System.Configuration.Configuration config =
WebConfigurationManager.OpenWebConfiguration (path);

MembershipSection configSection = ( MembershipSection
)config.GetSection( "system.web/membership" );
ProviderSettings settings = ( ProviderSettings
)configSection.Providers[mp.Name];

if ( settings == null )
{
//try the web.config file at the root of the default web site
config = WebConfigurationManager.OpenWebConfiguration( "/" );

configSection = ( MembershipSection )config.GetSection(
"system.web/membership" );
settings = ( ProviderSettings
)configSection.Providers[mp.Name];

if ( settings == null )
{
//try the app.config
config = ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None );
configSection = ( MembershipSection )config.GetSection(
"system.web/membership" );
settings = ( ProviderSettings
)configSection.Providers[mp.Name];
}
}

if ( settings != null )
{
NameValueCollection collection = settings.Parameters;
mp.Initialize( mp.Name, collection );
}
return mp;
}

I hope this helps someone unit test there custom membership providers.
