# Video: Designing For Testability

By Roy Osherove September 1, 2006 In [Agile](https://osherove.com/blog/category/agile), [Agile Related](https://osherove.com/blog/category/agile-related)

**Historical article** · Originally published September 1, 2006; technical details may be outdated.

You can now download my presentation video from DevDays Belgium Entitled "Designing For Testability" from last year.

Stuff I cover in this talk:

- Basic design principles that help make sure your code will be testable
- Using "Fake" objects (Stubs and Mocks) and how Interfaces play a role
- Overcoming common hurdles such as Singletons, static methods, private methods, constructor logic and more

You can download this via a torrent file _(Be kind, **keep seeding** it after you've downloaded it)_:

The more people download, the better the download speed. Thanks for helping to  seed this thing.
