pass_nils_to

Pass nils to your methods and see if they explode.

Installation

Install the gem directly:

gem sources -a http://gems.github.com (you only have to do this once)
sudo gem install pelargir-pass_nils_to

Or install the gem in your Rails project:

gem sources -a http://gems.github.com
script/plugin install pelargir-pass_nils_to

Or clone the project:

git clone git://github.com/pelargir/pass_nils_to.git

Pass nils to your methods thusly:

class Parser
  def parse(arg1, arg2)
    ...
  end
end

parser = Parser.new
pass_nils_to(:parse, parser)

This would pass nils to the #parse method in these combinations:

parse(nil, "foo")
parse("foo", nil)
parse(nil, nil)

An arbitrary number of arguments are supported, so you can try passing nils to methods with three arguments, four, five, etc.

Use the rake command to run the unit tests for the plugin. The tests require that the Mocha gem be installed locally:

sudo gem install mocha
