100% test coverage with rcov

Further to my previous post, coverage is now at 100%.

Fixing that last 4% was mostly a matter of:

• finishing the writing of my tests (obviously). The missing ones were for the post actions in my main controller
• excluding the standard config files boot.rb and environment.rb from the report, the former because of some standard platform-specific stuff (unreachable in my setup) and the second because (bizarrely) it reported that I wasn't achieving full coverage of its comments! Added --exclude boot.rb,environment.rb as the first argument to rcov.

There was also an issue with code of the following form:

  x = y.collect do |i|
    i.to_s
  end.join("/")

For some reason, rcov failed to recognise the execution of the last line. I had good reason to rewrite this, so I haven't investigated this any further.
