You can unit test your mapster configuration by created a new mapper instance and adding your implementation classes of the IRegister to the config.

This code will search for IRegister interfaces and inject them into a instance of the mapster mapper.

public static class AddMapsterForUnitTests
{
    public static Mapper GetMapper()
    {
        var config = TypeAdapterConfig.GlobalSettings;
        config.Scan(typeof(ImplementationOfIRegisterClass).Assembly);
        return new Mapper(config);
    }
}

And then in your unit test Arrange method:

// Arrange
var mapper = AddMapsterForUnitTests.GetMapper();
