Show HN: Tusk Drift - Turn production traffic into API tests
Hi HN! In the past few months my team and I have been working on
Tusk Drift, a system that records real API traffic from your
service, then replays those requests as deterministic tests.
Outbound I/O (databases, HTTP calls, etc.) gets automatically
mocked using the recorded data. Problem we're trying to solve:
Writing API tests is tedious, and hand-written mocks drift from
reality. We wanted tests that stay realistic because they come from
real traffic. versus mocking libraries: Tools like VCR/Nock
intercept HTTP within your tests. Tusk Drift records full
request/response traces externally (HTTP, DB, Redis, etc.) and
replays them against your running service, no test code or fixtures
to write/maintain. How it works: 1. Add a lightweight SDK (we
currently support Python and Node.js) 2. Record traffic in any
environment. 3. Run `tusk run`, the CLI sandboxes your service and
serves mocks via Unix socket We run this in CI on every PR. Also
been using it as a test harness for AI coding agents, they can make
changes, run `tusk run`, and get immediate feedback without needing
live dependencies. Source: https://github.com/Use-Tusk/tusk-drift-
