Ruby: An Introduction to Behavioral Driven Development with RSpec and Cucumber

On October 20, 2009 at 6:30, I'm going to be giving a talk for the East Bay Ruby Meetup Group called "An Introduction to Behavioral Driven Development with RSpec and Cucumber". This is an introduction to behavioral driven development in Rails using Cucumber, RSpec, Webrat, and factory_girl.

For the second time in my life, I finished preparing several days before the actual talk. If you're interested, here are the slides.

Happy testing! :-D

I'm glad to see you've fully embraced the dark side. ;-)

Haha. Thankfully, I'm still multilingual. I work at two startups--one Python and one Ruby. I gave two talks this month--one Python and one Ruby ;)

Thanks for this talk! I recommended your slides to some of my former colleagues, because I like your setup and I think you have some good and concise comments on testing in general.

Thanks, Ben!

How did the talk go? Did you really present all 75 of the slides? That must have been a very long talk :p

Even though I am a python guy I like the exploratory path you've taken. In particular I would love to have something instead of "fixtures" in django that can make it easier for me to populate the db for testing.

Also liked your discussion on ruby vs. haskel, lack of interfaces and misspellings.

If I may suggest in the future to focus on one particular topic (your presentation seems to go back and forth sometimes). 20 slides should do it ;-)

Also - I am really curious by reading your blog whether you have read Code Complete 2? Either you've read it (in which case great) or you haven't (in which case I think you should) :-)

Hey Andriy,

> How did the talk go? Did you really present all 75 of the slides? That must have been a very long talk :p

The talk went very well. We made it through all the slides, and the questions were pretty good. We had to speed up a bit toward the end, but everyone seemed to really enjoy the talk.

Yep.

Thanks.

Thanks for the suggestion, but I was actually doing what they asked me to do. They wanted a) an introduction to BDD, RSpec, and Cucumber b) some opinions and advice c) (at least implicitly) an explanation of why they should test. You're right, there are 3 20 minute talks in there, but I only get one shot to talk, and it's for 60 minutes ;) As for 20 slides, I wrote the slides for people like you who couldn't be at the talk. Hence, I went way overboard on purpose. My guess is that more people will read the slides than were actually at the talk.

> Also - I am really curious by reading your blog whether you have read Code Complete 2? Either you've read it (in which case great) or you haven't (in which case I think you should) :-)

I read his other book, "Professional Software Development" (I blogged a summary of it here: http://jjinux.blogspot.com/2006/04/software-engineering-professional.html). I've been hesitant to read "Code Complete" because I read really slowly, and it would take me forever. The massive book I'm committed to right now is "Concepts, Techniques, and Models of Computer Programming".

"I read his other book"
Well the reason I asked is because he explores and presents a lot of facts about testing, and how it is relevant or not. One of the more interesting things for example is that code reviews or pair programming eradicates more bugs than unit testing.

Regarding long read - it reads very easy.

Yep, he said the same thing in "Profession Software Development". That matches my own experience too, which is why I'm such a fan of code review.

Okay, okay, I'll put it on my reading list ;)

Drawing Sierpinski's Triangle in Minecraft Using Python

In his keynote at PyCon, Eben Upton, the Executive Director of the Rasberry Pi Foundation, mentioned that not only has Minecraft been ported to the Rasberry Pi, but you can even control it with Python. Since four of my kids are avid Minecraft fans, I figured this might be a good time to teach them to program using Python. So I started yesterday with the goal of programming something cool for Minecraft and then showing it off at the San Francisco Python Meetup in the evening.

The first problem that I faced was that I didn't have a Rasberry Pi. You can't hack Minecraft by just installing the Minecraft client. Speaking of which, I didn't have the Minecraft client installed either ;) My kids always play it on their Nexus 7s. I found an open source Minecraft server called Bukkit that "provides the means to extend the popular Minecraft multiplayer server." Then I found a plugin called RaspberryJuice that implements a subset of the Minecraft Pi modding API for Bukkit s…

Apple: iPad and Emacs

Someone asked my boss's buddy Art Medlar if he was going to buy an iPad. He said, "I figure as soon as it runs Emacs, that will be the sign to buy." I think he was just trying to be funny, but his statement is actually fairly profound.

It's well known that submitting iPhone and iPad applications for sale on Apple's store is a huge pain--even if they're free and open source. Apple is acting as a gatekeeper for what is and isn't allowed on your device. I heard that Apple would never allow a scripting language to be installed on your iPad because it would allow end users to run code that they hadn't verified. (I don't have a reference for this, but if you do, please post it below.) Emacs is mostly written in Emacs Lisp. Per Apple's policy, I don't think it'll ever be possible to run Emacs on the iPad.

Emacs was written by Richard Stallman, and it practically defines the Free Software movement (in a manner of speaking at least). Stal…

ERNOS: Erlang Networked Operating System

I've been reading Dreaming in Code lately, and I really like it. If you're not a dreamer, you may safely skip the rest of this post ;)

In Chapter 10, "Engineers and Artists", Alan Kay, John Backus, and Jaron Lanier really got me thinking. I've also been thinking a lot about Minix 3, Erlang, and the original Lisp machine. The ideas are beginning to synthesize into something cohesive--more than just the sum of their parts.

Now, I'm sure that many of these ideas have already been envisioned within Tunes.org, LLVM, Microsoft's Singularity project, or in some other place that I haven't managed to discover or fully read, but I'm going to blog them anyway.

Rather than wax philosophical, let me just dump out some ideas:Start with Minix 3. It's a new microkernel, and it's meant for real use, unlike the original Minix. "This new OS is extremely small, with the part that runs in kernel mode under 4000 lines of executable code." I bet it&…
