Hi,

I would like to test my BO biz rule. However, I don't want to connect to actual database, so that the testing can completed faster. Additionally, I would like to have "dependecy injection" for data layer so that I could prepare my test data there.



What is the recommended approach to do this in SF environment?



Thank you

You would need to overload the GetCustomerType() method to allow you to pass a parameter that would tell whether it can use database access.  So, if you call GetCustomerType(false) and you have all the information you need in memory, then it won't need to connect to the database again, just return the cached value.  Otherwise, if you don't have the data already retrieved then you're still going to probably need to retrieve the value from the database.
