DevOps, not programmer.
Why not? Why doesn't the programmer want to test a container?
True. Nothing beats running your unit tests in the actual container image that will be run in production.
Race condition that only happens on the much faster production hardware: Allow me to introduce myself

Unit tests can’t win ’em all. That’s where things like integration tests, staging environments, and load testing come in.
The final layer of protection is the deployment strategy, be it rolling, canary, or blue-geen.
