What Keploy Gets Wrong About Speedscale
Keploy's Speedscale comparison gets the architecture wrong. Check its claims against the docs for eBPF capture, TLS, automatic mocks, and local testing.
What Mocks Are Actually For
Part 1 of Getting Started with Mocks: the one job a mock does, the five situations where you need one, and what a green mocked test does not prove.
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.
WireMock alternatives: pick the one that fits your problem
A 2026 take on WireMock alternatives. Keep WireMock for what it's good at; add Microcks (now CNCF Incubating) or proxymock for the gaps. The honest map.
Build WireMock mappings fast from real traffic
Generate WireMock mappings from recorded HTTP traffic. Review matching fields, sensitive values, eligible pairs, and custom changes before reuse.
Capture Encrypted Microservice Traffic with Speedscale eBPF
Inspect encrypted microservice traffic with Speedscale’s eBPF collector. Check TLS support, node permissions, and Java-agent rollout requirements first.
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.
