First post so hi all :slight_smile:

can anyone tell my how can i test my custom repositories?
i have a repo which is using umbraco database:

public class MyRepository : IMyRepository
{
protected readonly UmbracoDatabase db;

    public MyRepository()
    {
        db = ApplicationContext.Current.DatabaseContext.Database;
    }

    public void EditRestaurant(Restaurant restaurant)
    {
        var updatedRestaurant = db.SingleOrDefault<RestaurantPoco>("SELECT * FROM Restaurants WHERE Id = @0", restaurant.ID);
        if (updatedRestaurant == null)
        {
            throw new KeyNotFoundException("Restaurant has not been found.");
        }

        db.Update("Restaurants", "Id", Mapper.Map<Restaurant, RestaurantPoco>(restaurant, updatedRestaurant));
    }
}

i would like to use test database for my unit tests.

How can i do this?

thx in advance for help
