Use Cases, User Stories and Test-Driven Development (TDD)

"Test-driven development (TDD) is a software development technique that uses short development iterations based on pre-written test cases that define desired improvements or new functions. Each iteration produces code necessary to pass that iteration's tests. Finally, the programmer or team refactors the code to accommodate changes. A key TDD concept is that preparing tests before coding facilitates rapid feedback changes. Note that test-driven development is a software design method, not merely a method of testing.

To write a test, the developer must clearly understand the feature's specification and requirements. The developer can accomplish this through use cases and user stories that cover the requirements and exception conditions. This could also imply a variant, or modification of an existing test. This is a differentiating feature of test-driven development versus writing unit tests after the code is written: it makes the developer focus on the requirements before writing the code, a subtle but important difference."

    Interesting meeting. A little unorganized, but this was by design, and as the meetup progresses it will likely become more organized. The other attendees were a hardcore group of programmers, and networking opportunities with interesting people abound. I did in fact learn a bunch about TDD. The collective mind is a valuable tool.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
