Fuzz Testing Go HTTP Services

Fuzz testing, or fuzzing, is an automated software testing technique used to find bugs, crashes, and security vulnerabilities by inputting large amounts of random data into a program. It is now integrated into Go’s standard library as of Go 1.18, making it part of the regular testing package. Fuzz testing can reveal bugs that traditional testing might miss and is a recommended practice for improving the robustness of code, including HTTP services. The post provides step-by-step instructions for creating fuzz tests in Go, including an example for fuzzing HTTP handlers using Go's `httptest` package.
