Masaru Ishii, a great Japanese Rubyist, died at the rail disaster, where 106 people died. He introduced RubyUnit with the author1, Suketa-san. It was the predecessor of the current Test::Unit in Ruby 1.8.
I love unit testing. I pay his last respects. I don’t know what to say in English. I hope I don’t use incorrect words. I learned RubyUnit from Suketa-san’s book.
1 According to this blog, Ishii-san asked Suketa-san to create a Ruby implementation of xUnit.
