Testing:
- Testing
is paramount for V&A. We are obsessive about conducting rigorous
tests. We test in an environment that mirrors real world conditions as
close as possible. We will stress test every object at each step
extensively for days and/or millions of transactions before
deployment.
- White-box,
black-box, regressive, volume and other tests are performed according
to the application.
- We
use existing testing tools and/or the ones we build
ourselves.
- Hardware
is tested for reliability, response time, bottlenecks, uptime,
recovery, component hot-swapping, redundant power, ventilation, etc.
- Software
is tested for reliability, capacity, error handling, data validation,
consistency, irregular termination and recovery, backup routines,
archiving, purging, etc.
User
issues and error logs will be kept for review. We go as far as
creating a complete audit trail with automatic notifications to
administrators via email/pager or other alarms, according to the
severity and the user’s preferences. Issue escalation will be built-in
when no response or inadequate response is
provided.
