[LRUG] API automation / load testing

[Alex Reis]

Might be overkill for your needs, but I tend to use Apache JMeter a
lot, since that lets you record (and edit) user sessions, then play
them back with a ramping up number of threads, different scenarios and
with some programming capabilities (loops, ifs, variables). It can
also be used to coordinate a test launching in multiple hosts so you
don't get to exaust the capacity on your machine before the server
feels it like others said.

There's also the Tourbus library for what it's worth -
https://github.com/dbrady/tourbus/ - if you have good capybara-ish
tests, you can turn them into realistic load test scenarios easily.

Cheers,

Alex
