Mruby: Errors in Ruby code and how to find them

As developers, we love our booleans. They map perfectly into how computers work at a low level and play nicely with if statements, our primary control-flow tool. They are simple to reason about. What's not to like? We actually like them so much that we use them for domain modeling. And that's where things get problematic. I would like to show you...

And if it is a storytelling act, perhaps we should look into narrative principles to make our tests better? One of the first...

Now it’s time to try to look further and build something more complex. But first, let me just acknowledge how really basic the mruby is. It supports almost all Ruby syntax...

I knew that DragonRuby has some kind of relation to mruby - be it written in it or using some kind of fork of it. But that’s pretty much it.
