# New Online Course: TDD and BDD in Ruby

By Roy Osherove September 15, 2013 In [BDD](https://osherove.com/blog/category/bdd), [course](https://osherove.com/blog/category/course)

**Historical article** · Originally published September 15, 2013; technical details may be outdated.

If you are just coming into the Ruby community, you might think “man; everyone here does unit testing and TDD already”. But the truth is, that is very far from reality. Most people in Ruby seem to talk the talk, but very few that I’ve seen actually walk the walk.

Yes, many of them do have tests, but very few do things test driven. It’s just very difficult without a guiding hand sometimes. So many developers slack off and write the tests after.

Worst, many developers do not know how to write anything but integration tests. There is lots of good stuff in integration tests, but they can also be very slow for a good feedback cycle.

Unit testing is necessary to learn, and doing things test driven can make you more productive in the long run (I discuss some numbers during the course).

**YOU DO NOT NEED ANY PREVIOUS UNIT TESTING EXPERIENCE.**

I will teach you from zero how to write your first unit test with RSpec (and why RSpec) , all the way to making you a master of the craft with mock objects, stubs, and how to choose an isolation (mocking) framework.

You will also learn about making a continuous delivery solution and some patterns for getting started with a project on the right path.
