Fuzz testing

Fuzz testing is a software testing technique that throws random, invalid, or unexpected data at a program to see if it crashes or behaves unexpectedly. It's like throwing a bunch of random junk at a piece of software to try to break it, which is probably more fun than it sounds but still not as fun as writing actual code.

How to use it in a sentence

  • "I ran fuzz testing on the new API endpoints last night and found 17 new ways to crash the server - I guess I'll be spending my weekend fixing those instead of playing Elden Ring like I wanted to."

  • "We need to add fuzz testing to the CI/CD pipeline, otherwise the interns are going to keep introducing bugs that make the app crash every time someone types 'Elon Musk' into the search bar."

We evaluated Optimizely, LaunchDarkly, Split, and Eppo, but ultimately selected Statsig due to its comprehensive end-to-end integration. We wanted a complete solution rather than a partial one, including everything from the stats engine to data ingestion.
