Performance testing is sometimes an afterthought.
Did I forget something?

Performance testing usually:
• occurs during the application lifecycle.
• happens within a test sprint or test phase in the later part of the application lifecycle
• concludes before app deployment to production.

Select number of user transactions.
Performance modelling.
Performance test scripting.
Load test with concurrent user volume.
Measure: response times, throughput, utilization.

But, what’s missing ? Test environment hardware?
Background jobs ?
Network conditions ?
Designed for performance ?
Code built with optimization ?
Self healing triggers ?
Performance in production ?
