CWE Top Most Dangerous Software Weaknesses
Out of this frustration I've built: https://github.com/Endava/cats. It's for APIs, but mostly addressing exactly this case: don't use strings for everything, if you choose to use it though, make sure you add patterns for checking if things are valid, make sure you think about all the corner cases and all the weird characters that can brake you app, and so on.

Cucumber Maintainer out of Job and future of the project is uncertain
This is why we need better tools which will give benefits for the added complexity. If you need to create both the feature files AND the code, it's just complexity with little benefits. But frameworks like https://github.com/karatelabs/karate or https://github.com/Endava/cats are hiding this complexity and remove the code layer entirely. Which, in my view, this is where you need to be in 2023, particularly for API testing.

Invisible Characters
I've built a tool specifically to test if these kind of characters will reach API backends: https://github.com/Endava/cats. My idea was that APIs should explicitly reject or sanitise input containing such characters.

Hey Rustaceans! Got a question? Ask here! (32/2022)!
Hi, I'm working on a fuzzer, that fuzzes APIs based on OpenAPI specification. I'd like to implement shrinking. It means that when an interesting input (for the API) is found, I'd like to create the smallest possible input that still causes the same behaviour of the API. I'd like to implement a payload generation via proptest, because it already has the shrinking ability. I'm having issues implementing the JSON object as a proptest strategy. Here is what I tried so far. I explained it in a detail in stackoverflow question but it did not reach many people. Thanks for your help!

Show HN: OpenAPI fuzzer – fuzzing APIs based on OpenAPI specification
Thanks for the report. However, without more information I'm not able to help you. What is your setup? How did you run it? could you please share the specification file? Also, let's probably move this discussion to GitHub issues: https://github.com/matusf/openapi-fuzzer/issues
What are some alternatives?
