API Fuzzing Examples

This repo created for the LASCON '2023 conference talk shows simple APIs with automated tests including unit and fuzz tests.

The reverse service implementation is based on the Getting started with fuzzing tutorial.

Compile

You can compile the app using go build.

Unit Tests

Execute them using the standard go test command.

Run The Fuzzing Tests

For example, this command runs the reverse server fuzzing tests for 10 seconds

go test -v --skip Test -fuzz=FuzzReverseServer --fuzztime 10s

Illustrating Buggy Implementation

In reverseserver.go, change the Reverse function to use Reverse_Buggy. The fuzzing tests will quickly find an issue.
