# Fuzzing Istio Code

The Istio (Go) code base is fuzzed using native Go fuzzing.
For general docs on how to fuzz in Go, see [Getting started with fuzzing](https://go.dev/doc/tutorial/fuzz).

## Writing a test

Generally, writing a fuzz test for Istio is the same as any other Go program.
However, because most of our fuzzing is based on complex structs rather than the primitives Go supports natively,
the `pkg/fuzz` package contains a number of helpers to fuzz.
