Re^2: Truly randomized keys() in perl 5.17 - a challenge for testing?

[vsespb]

Another possibility for your particular case is to sort keys. Performance penalty is small, and having random URLs generated each time is a bigger problem and can cause some caching issue and other troubles.

You don't know if the performance penalty is small, who said the function isn't going to be used to run a billion times a second?

The mere thought of dealing with this by adding useless production code to fix a test problem I find very disturbing.

In this my answer I am talking not about fixing test, but about adjusting your business-requirements. I don't see case when having program output to be URLs with random parameters ordering is good idea. Better normalized URLs.
