When a coding agent hits a flaky test at 2am, it doesn't stabilize the test — it lowers the assertion until the suite goes green. Here's what that actually costs you, and the cheap gate that catches it.
Read articleWhen the model writes both the handler and the test, green CI proves almost nothing. Here's the cheap structural fix that catches the failure mode.
Read articleA clean architecture diagram can hide a broken transition. Trace one failure boundary, verify it in code, and turn it into an API scenario test.
Read articleA failing request needs its environment, caller, and starting state. Preserve those conditions when handing an API investigation to AI.
Read articleA create-read-check scenario connects an API contract, MCP tools, and observable outcomes. Here is how to make completion something you can verify.
Read articleMCP connects agents to tools; A2A connects agents to other agents. Debugging A2A means pinning the incompatible 1.0/0.3 wire version, reading the Agent Card, walking the task lifecycle, streaming events over SSE, and pinning the JWKS out of band.
Read articleYour favorite saved request probably exercises the easiest path. Change one input at a time to find the assumptions hiding behind a green Send button.
Read articleA green status code can hide a broken integration. Here are five checks that reveal what your happy-path request misses, with a small contract test you can run today.
Read articleThe same example payload is usually hand-copied into docs, a mock server, a Postman collection, and test fixtures, and then they drift. OpenAPI examples can drive all four from one document, but only if they are realistic, schema-valid, and cover success, empty, and error states.
Read articleAn MCP server is just JSON-RPC over a transport, which means it is fully testable without an AI in the loop. Here is a practical ladder: Inspector for discovery, curl for the protocol, and deterministic automated tests for schemas, errors, and side effects in CI.
Read articleA scanned document is only worth something if the team exercises it. Start a mock for blocked consumers, chain real scenario tests against staging, and serve the spec as an MCP server for internal agents.
Read articleConsumer-driven contracts with Pact are powerful but bring a broker, pactfiles, and a workflow small teams never maintain. Here is what contract testing is really protecting, and a lighter OpenAPI-based setup that catches the same integration bugs with tools you already run.
