marvin-js
Just another web testing framework
In the beginning the universe was created.
This has made a lot of people very angry, and
been widely regarded as a bad move.
It's 2000 A.D.
We survived the millenium bug, and F. Marchetti created YOOX
One of the most recent opportunities was
improve our quality assurance process
Time consuming
Repetitive work
Regressions
Docs
Legacy Browsers
Internet Explorer
Bug Triage
Bottleneck
Late discovery
An increasing HUGE number of online stores,
A lot of localizations, and sometime even exceptions.
Quality assurance is not a game for the weak of heart.
Automation
[aw-tuh-mey-shuh n]
The technique, method, or system of operating or controlling a process by highly automatic means, as by electronic devices, reducing human intervention to a minimum.
