Test Driven Development

• incremental process
• drives implementation with tests
• results in an exhaustive regression test suite
• should focus on design
• should focus on documentation
• should focus on behavior

Behavior Driven Development is like TDD, but with the following added:

• includes focus on design
• includes focus on documentation
• includes focus on behavior

Short demo on ping-pong pair programming. You write the smallest test you can to cause failure. The other person writes the simplest code to make the test pass.

Overview of the BDD/RSpec Timeline.

November 2007 (knock on wood): RSpec-1.1.0

Story Framework - Executable User Stories

Something about rbehave flashed on the screen.

Demo of the Story Framework. Testing that read as prose (same concepts as Hoare Logic, but reads better). This looks pretty cool and useful.

Demo of a tool in its infancy that Tech Support, QA, and business people can use to poke the system.

Quick look at RSpec Results. You can have pending tests.

Something about integrating with legacy projects flashed on the screen.

miniunit/minirspec will be shipped with Ruby 1.9.
