I’ve checked them and they do, but in my opinion test_name_sticks should fail as every call to name will append a new random name to the previous one instead of returning the same string.

Just like every other time I have to deal with XML, I do two things: Throw up a little bit. gem install nokogiri I found lots of code samples, including in the Nokogiri tutorials, that discussed how to create a new node and then insert a string as the node contents. This would have been ok if my node contents didn’t contain more nodes. Nokogiri tried to be helpful and escaped the node contents. So, not very many < and >, but lots of &gt; and &lt;. ...

Rather than writing object.map{ |o| o.action }, I just found out that I could write object.map(&:action). I’m currently attempting to suppress a very strong urge to refactor everything in my current project. No curly braces, no pipes? Sign me up! src & in the Ruby docs

As the bot goes on, its algorithm degrades as elements of randomness are introduced.

XML is like violence - if it doesn’t solve your problems, you are not using enough of it. Nokogiri project page Starting a new project today that will heavily involve, you guessed it, XML.
