Question

I wrote my own settings manager, serialization is provided by BinaryFormatter. It is cool becouse, it can load and save class with missing/added property and I can define default value in missing property. But I have problem to test it with unit test.

I am doing this by myself. How to do this scenario automatically?

1. Write class with 1 property.
2. Serialize this class by my settings manager.

Before run new test:

1. Manualy edit class and add new property, so we have two properties. New one with setted default value in [OnDeserialized] method.
2. Run completely new test after rebuild new class.
3. Class is deserialized from binary file.
4. New property has default value.

It works like a charm, but I dont want to do this by myself. I need some automatic test.

Please, dont question my architecture, focus on my problem.

Posible way:
Reclection? Other class? What about namespaces?

Answer 1

You can make two classes one for serialization and one for de-serialization and use SerializationBinder while de-serializing to the other class.
