restler-fuzzer

It is popular in domains where it’s effective but it’s not as useful when it’s hard to know if an output is correct. I know several tools which fuzz mobile app UIs to see if you can cause crashes or irrecoverable states with random inputs because those are easy to detect, but beyond that you start needing to have more traditional QA approaches to say whether the resulting state is correct. One area which is very interesting is the use of OpenAPI schemas to help with APIs since you can use the schemas to guide generation and validation. It’s non-trivial to do with authentication but I found this project of interest: https://github.com/microsoft/restler-fuzzer

There's another one here by Microsoft - this is cool though! great to see more Rust tools. https://github.com/microsoft/restler-fuzzer
