Sequence Tweaking Spock Extension

Quick and easy generation of int[] sequences for Codility and Leetcode algorithm challenge test cases

Recently I've been catching up on modern Java.. I haven't used it on the job since Java 5 came out. I've been practicing algorithms on Codility and Leetcode.

The algorithm puzzles on these sites almost always use int and/or int[] arguments and return types, and sometimes have BigO performance requirements. To test your algorithms properly, you need to generate very large input arrays, of sizes up to 100,000 with values from +/- 1 billion. My test cases weren't anywhere near as comprehensive as those run by Codility when you submit you solution, and I wanted a way to quickly create tests to cover edge cases and very large inputs.

I started using the data tables feature in the awesome Spock testing fram

	* How to install it:
	* - go to page [[roam/js]]
	* - create a node with: { {[[roam/js]]}}
	* - create a clode block under it, and change its type from clojure to javascript
	* - allow the running of the javascript on the {{[[roam/js]]}} node

	# put this in your .bash_profile
	if [ $ITERM_SESSION_ID ]; then
	export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
	fi

	# Piece-by-Piece Explanation:
	# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
	# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
	# the $PROMPT_COMMAND environment variable is executed every time a command is run
