Production tests requirements:

• Less coverage than automated test suites
• Quick and simple
• Reliable (no flakiness / false allerts)
• Not too functionality-specific (unlikely to be broken by feature changes)

Advantages of production tests:

• Real world testing
• Troubleshooting
• Observability for low traffic regions
• Safer Deployments
• Reuse in other environments

Disadvantages of production tests:

• Setup and teardown challenges
• They sometimes need setup of scenarios
• They can be flaky
• They cause resource usage and costs
• Human cost in maintaining tests

Monitoring real traffic on production allows for locating problems with:

• Latency
• Reliability
• Assertions
• Failures

So, designers, please find the players everyone else hates. Find them and coerce them into play games with you. Don’t guide them or help them or anything else, let them make the most ridiculous and broken interpretations and then fix them afterwards.
