How Keploy uses eBPF to capture your API calls and auto-generate tests and mocks — without changing a line of code. Writing API tests is the thing every developer knows they should do and nobody wants to do. The setup is tedious, the mocks go stale, and the tests break every time a schema changes. By the time you’ve written tests for one endpoint, three more have shipped without coverage. Keploy takes a different approach: instead of writing tests, you run your app and let real traffic become your test suite. Here’s how it works and how to get it running in under ten minutes. What Keploy Actually Does Keploy sits at the network layer using eBPF — it intercepts API calls, database queries, and service-to-service traffic at the kernel level. No SDK to install. No code to modify. No language-specific instrumentation. When you run your app under keploy record , every real API call becomes a test case. Every database query, external API call, and service dependency gets captured as a mock.…
