Learning about test automation with Lego
“Hold on, did you say that I can learn about test automation by playing with Lego? Shut up and take my money!” Yes, I am indeed saying that you can. It will cost you a couple hundred Euro’s, because Lego isn’t cheap, especially the Mindstorm EV3 Lego. It turns out that Lego robots eat at a lot of AA batteries, so buy a couple of packs of these as well. On the software side you need to have a computer with a Java development environment and an IDE of your choice (the free edition of IntelliJ IDEA will do).
“Okay, hold on a second. Why do you need Java? I thought Lego had its own programming language?”. Yes, that’s true. Orginally, Lego provides you with their own visual programming language. I mean, the audience for the EV3 is actually kids, but it will be our little secret. Because Lego is awesome, even for adults. Some hero made a Java library that can communicate with the EV3 hardware, LeJos, so you can do more awesome stuff with it. Another hero dedicated a whole website to his Mindstorm projects, including instructions on how to build them.
