Hello,

Is Test::Unit always producing 0 errors?

I have the solution!

Stir in a packet of RandomMethod and "Hey Presto!", a return to the
delights of indeterminacy!

# RandomMethod mixin
# 0.0.6
# by thoran
# 20060319
# Raison D'etre: Because I can!?
# Acknowledgements: I used a bit of John W. Long's posting to ruby-talk
from 2004-07-31 for the random bit although it looks a bit different
now.
# Changes: It is within a begin-rescue block now, since no parameters
are being passed it would sometimes fail and so will now try until it
finds a method that works without parameters.

module RandomMethod
def random_method
begin
methods = self.methods
random_method = methods[rand(methods.size)]
self.send(random_method)
rescue
random_method
end
end
end

Perhaps this can be my entry into Ruby Quiz of the Week's as yet
unannounced 'quiz': 'Stupidest Ruby Code Ever Competition?' Perl has
competitions for obfuscation; how about we go for obtuseness?

Actually is there *any* good purpose to this?

P.S. I've already started thinking about the next version, or a similar
thing, which will automatically randomize methods on object creation or
method call using meta-classes...

None I can think of? :)

you call() on a string rather than on the object.
Improved version with 'usecase' :

module RandomMethod
def random_method
m = methods - Object.new.methods -
Object.methods - ["random_method"]

m.reject{|n| method(n).arity.nonzero?}
method(m[rand(m.size)]).call() if m.size > 0
end
end

class Dice
include RandomMethod
def one; 1;end
def two; 2;end
def three; 3;end
def four; 4;end
def five; 5;end
def six; 6;end
end

dice = Dice.new
10.times{puts dice.random_method}

Nah :)

Im putting in Method objects in the collect block.

Your version, however, looks nicer.

Why stop there?

$DEBUG=false
$SAFE=3

# On the theory that if something goes wrong, you should just
# try something else until you find something that works.
module DuckDebugging
def method_missing(meth, *args, &block)
m = methods
meth2 = m[rand(m.size)]
result = send(meth2, *args, &block)
rescue => ex
p [self, meth2, args, ex] if $DEBUG
retry
else
p [self, meth2, args] if $DEBUG
result
end
end

class Object
include DuckDebugging
end

result = (now your program can be any batch of garbage
just enter words at random and you will get something)

p result

Willie is a sad example of what too much of Usenet has become; a
playground for sad little wankers whose only self-validation is the
volume of their squalling, no matter how stupid they appear.

Tired, Freddie, tired. Even for you.

And that pronouncement comes from one of the Usenet's best known, and
most discredited, trolls. What a hoot.
