Unit testing some methods that aren't required by outside objects.

I have my database layer:

public class DataBaseLayer
{
    public Result runQuery(Query q)
    {
        this.openSession(); 
        this.runPackage(q);
        Results r = this.fetchResults();
        this.closeSession();
        return r;
    }

}

Currently all those methods are private methods.

But I want to be able to test them.

for example

private void testOpenSession_wrongUserNamePassword_returnsBadUserNamePassWordError();
private void testrunPackage_insufficientPrivileges_returnsInsufficientPrivlegesError();

The question is what's the nicest way of doing this?

I figure I could either:

• Just test the runQuery method for bad username password etc.


• Make those methods protected.


• Make those methods public.
