Commandline

bin/ has some commandline scripts to generating diffs

Either use the following scripts

node bin/gen.screenshots.js --help
node bin/diff.screenshots.js --help

OR this script

node bin/gen.visual_diff.js --help

Testreduce client

testreduce/ has client scripts and example config for mass testing of visual diffs by getting titles from a testreduce server (either from the Parsoid codebase or from the testreduce repo on github once that is ready for use).

There is an example testreduce server settings file there as well.

Diff server

Thin server for generating diffs to be used in combination with testreduce server to look at diffs (since the server doesn't have the actual images, just a numeric score).
