#11 Refactoring User Name Part 2

Hi Ryan,

Testing is about proving that the code is fit for purpose.

Regression testing is about proving that the modified/new code does not impact on the existing code - which is what you are hinting at above.

One other thing to consider is if first name or last name is an empty string. You can do something like:

[first_name, middle_initial_with_period, last_name].reject(&:blank?) * ' '

This will reject all blank values.

I think you mean something like this:

[f, m, l].reject{|i| i.empty?}.compact.join(" ")

Yay Ruby. ^.^

Hello,
  Great site and great coding! I would like to see a railscast on Rspec. Any plans for that?

I cannot get autotest to work on XP. I get error message "couldn't find HOME environment.." What should I add to the environment variable setting in Window?
