GoSemanticFuzz is a library for populating go objects with semantically correct random values.
This is useful for testing:
- Do your project's objects really serialize/unserialize correctly in all cases?
- Is there an incorrectly formatted object that will cause your project to panic?
Import with import "github.com/rajatmjain/GoSemanticFuzz/gosemanticfuzz"
You can use it on single variables:
// String Fuzzer
var A string
unicodeRange := goSemanticFuzz.UnicodeRange{First: '0', Last: 'ӿ',MinLength:12,MaxLength: 25}
stringFuzzer := goSemanticFuzz.New().Funcs(unicodeRange.CustomStringFuzzFunc())
stringFuzzer.Fuzz(&A)
fmt.Println("Fuzzed string: ",A)// Integer64 Fuzzer
var B int64
int64Schema := goSemanticFuzz.Int64Schema{Minimum: 0,Maximum: 10000}
int64Fuzzer := goSemanticFuzz.New().Funcs(int64Schema.CustomInt64FuzzFunc())
int64Fuzzer.Fuzz(&B)
fmt.Println("Fuzzed integer64: ",B)// Integer32 Fuzzer
var C int32
int32Schema := goSemanticFuzz.Int32Schema{Minimum: 0,Maximum: 10000}
int32Fuzzer := goSemanticFuzz.New().Funcs(int32Schema.CustomInt32FuzzFunc())
int32Fuzzer.Fuzz(&C)
fmt.Println("Fuzzed integer32: ",C)//Float64 Fuzzer
var D float64
float64Schema := goSemanticFuzz.Float64Schema{Minimum: 0,Maximum: 10000,Precision: 9}
float64Fuzzer := goSemanticFuzz.New().Funcs(float64Schema.CustomFloat64FuzzFunc())
float64Fuzzer.Fuzz(&D)
fmt.Println("Fuzzed float64: ",D)//Float32 Fuzzer
var E float32
float32Schema := goSemanticFuzz.Float32Schema{Minimum: 0,Maximum: 10000,Precision: 2}
float32Fuzzer := goSemanticFuzz.New().Funcs(float32Schema.CustomFloat32FuzzFunc())
float32Fuzzer.Fuzz(&E)
fmt.Println("Fuzzed float32: ",E)Happy testing!
