开源软件名称:google/gofuzz开源软件地址:https://github.com/google/gofuzz开源编程语言:Go 100.0%开源软件介绍:gofuzzgofuzz is a library for populating go objects with random values. This is useful for testing:
Import with You can use it on single variables: f := fuzz.New()
var myInt int
f.Fuzz(&myInt) // myInt gets a random value. You can use it on maps: f := fuzz.New().NilChance(0).NumElements(1, 1)
var myMap map[ComplexKeyType]string
f.Fuzz(&myMap) // myMap will have exactly one element. Customize the chance of getting a nil pointer: f := fuzz.New().NilChance(.5)
var fancyStruct struct {
A, B, C, D *string
}
f.Fuzz(&fancyStruct) // About half the pointers should be set. You can even customize the randomization completely if needed: type MyEnum string
const (
A MyEnum = "A"
B MyEnum = "B"
)
type MyInfo struct {
Type MyEnum
AInfo *string
BInfo *string
}
f := fuzz.New().NilChance(0).Funcs(
func(e *MyInfo, c fuzz.Continue) {
switch c.Intn(2) {
case 0:
e.Type = A
c.Fuzz(&e.AInfo)
case 1:
e.Type = B
c.Fuzz(&e.BInfo)
}
},
)
var myObject MyInfo
f.Fuzz(&myObject) // Type will correspond to whether A or B info is set. See more examples in You can use this library for easier go-fuzzing.
go-fuzz provides the user a byte-slice, which should be converted to different inputs
for the tested function. This library can help convert the byte slice. Consider for
example a fuzz test for a the function // +build gofuzz
package mypackage
import fuzz "github.com/google/gofuzz"
func Fuzz(data []byte) int {
var i int
fuzz.NewFromGoFuzz(data).Fuzz(&i)
MyFunc(i)
return 0
} Happy testing! |
