gofuzz is a library for populating go objects with random values.
This is useful for testing:
Import with import "github.com/google/gofuzz"
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 example_test.go

Happy testing!
