When Handwritten Mocks Stop Scaling
Part 9 of Getting Started with Mocks: a decision framework for stubs, fakes, fake servers, mock servers, record-and-replay, and real dependencies.
Your First Useful Mock
Part 2 of Getting Started with Mocks: a test you cannot write, one seam, and the smallest mock that makes a delayed package happen. Java, Node, Go, Python.
Your Mock Is Lying
Part 8 of Getting Started with Mocks: the carrier renames a field, production breaks, and every mocked test still passes. Java, Node, Go, Python.
The Compounding Platform Tax
Security controls rarely break a banking platform alone. Their cumulative divergence from Kubernetes standards creates a compounding maintenance tax.
Your Observability Stack Found the Fire. Congratulations.
Observability tells you when production is on fire. Capturing and replaying real traffic lets you recreate the incident, verify the fix, and keep it fixed.
Application Level Dependency Chaos Testing
A scoped chaos rule takes one dependency down and nothing else, so the fallback branch in your code executes on demand instead of during an outage.
Break One Dependency, Not The Whole Cluster
Scoped chaos rules are now in proxymock: pick traffic with a filter query, perturb it, and label every injected failure so it is never mistaken for a real one.
I built an API traffic classifier for business workflows
I pointed a classifier at 7,943 API calls to find business workflows. It worked, then showed where my assumptions about sessions and patterns fell apart.
