Test Driven Microservices System Confidence through Journeys, Traces & Contracts… @russmiles
Biker me… TBD
Say “Microservices” one more time… Reactive…
TBD
A Definition…
The kingdom of heaven is like a mustard seed, which a man took and planted in his field. Though it is the smallest of all seeds, yet when it grows, it is the largest of garden plants and becomes a tree, so that the birds come and perch in its branches (Matthew 13:31-32). - Of Mustard Seeds and Microservices (Micah Blalock) -- https://www.credera.com/blog/technology- insights/java/mustard-seeds-microservices/
“Loosely coupled service oriented architecture with bounded contexts”
Loosely Coupled Services that   can change
Which is GREAT! but…

The problem?
Front-end Only sucks
Acceptance in Microservices is Across Pipeline
Introducing ‘Journeys’
Introducing   ‘Pipeline Journeys’
Just expectation?
‘Live too’
That’s all good but…
Change?
Even Drop-in Replacement can be a Challenge!?
But there’s worse…
Contract Change.
*?it Happens…
We need to deal!
Event Sourcing is Key!
Size   doesn’t matter
SLOC doesn’t matter
Cognitive Overhead DOES
What can your System DO?

The real problem?
The general problem…
