Gofakeit
Random data generator written in go Features
Installationgo get github.com/brianvoe/gofakeit/v6Simple Usageimport "github.com/brianvoe/gofakeit/v6"
gofakeit.Name() // Markus Moen
gofakeit.Email() // [email protected]
gofakeit.Phone() // (570)245-7485
gofakeit.BS() // front-end
gofakeit.BeerName() // Duvel
gofakeit.Color() // MediumOrchid
gofakeit.Company() // Moen, Pagac and Wuckert
gofakeit.CreditCardNumber() // 4287271570245748
gofakeit.HackerPhrase() // Connecting the array won't do anything, we need to generate the haptic COM driver!
gofakeit.JobTitle() // Director
gofakeit.CurrencyShort() // USDSeedIf you are using the default global usage and dont care about seeding no need to set anything. Gofakeit will seed it with a cryptographically secure number. If you need a reproducible outcome you can set it via the Seed function call. Every example in this repo sets it for testing purposes. import "github.com/brianvoe/gofakeit/v6"
gofakeit.Seed(0) // If 0 will use crypto/rand to generate a number
// or
gofakeit.Seed(8675309) // Set it to whatever number you wantRandom SourcesGofakeit has a few rand sources, by default it uses math.Rand and uses mutex locking to allow for safe goroutines. If you want to use a more performant source please use NewUnlocked. Be aware that it is not goroutine safe. import "github.com/brianvoe/gofakeit/v6"
// Uses math/rand(Pseudo) with mutex locking
faker := gofakeit.New(0)
// Uses math/rand(Pseudo) with NO mutext locking
// More performant but not goroutine safe.
faker := gofakeit.NewUnlocked(0)
// Uses crypto/rand(cryptographically secure) with mutext locking
faker := gofakeit.NewCrypto()
// Pass in your own random source
faker := gofakeit.NewCustom()Global Rand SetIf you would like to use the simple function calls but need to use something like crypto/rand you can override the default global with the random source that you want. import "github.com/brianvoe/gofakeit/v6"
faker := gofakeit.NewCrypto()
gofakeit.SetGlobalFaker(faker)StructGofakeit can generate random data for struct fields. For the most part it covers all the basic type as well as some non basic like time.Time. Struct fields can also use tags to more specifically generate data for that field type. import "github.com/brianvoe/gofakeit/v6"
// Create structs with random injected data
type Foo struct {
Str string
Int int
Pointer *int
Name string `fake:"{firstname}"` // Any available function all lowercase
Sentence string `fake:"{sentence:3}"` // Can call with parameters
RandStr string `fake:"{randomstring:[hello,world]}"`
Number string `fake:"{number:1,10}"` // Comma separated for multiple values
Regex string `fake:"{regex:[abcdef]{5}}"` // Generate string from regex
Map map[string]int `fakesize:"2"`
Array []string `fakesize:"2"`
Bar Bar
Skip *string `fake:"skip"` // Set to "skip" to not generate data for
Created time.Time // Can take in a fake tag as well as a format tag
CreatedFormat time.Time `fake:"{year}-{month}-{day}" format:"2006-01-02"`
}
type Bar struct {
Name string
Number int
Float float32
}
// Pass your struct as a pointer
var f Foo
gofakeit.Struct(&f)
fmt.Println(f.Str) // hrukpttuezptneuvunh
fmt.Println(f.Int) // -7825289004089916589
fmt.Println(*f.Pointer) // -343806609094473732
fmt.Println(f.Name) // fred
fmt.Println(f.Sentence) // Record river mind.
fmt.Println(f.RandStr) // world
fmt.Println(f.Number) // 4
fmt.Println(f.Regex) // cbdfc
fmt.Println(f.Map) // map[PxLIo:52 lxwnqhqc:846]
fmt.Println(f.Array) // cbdfc
fmt.Printf("%+v", f.Bar) // {Name:QFpZ Number:-2882647639396178786 Float:1.7636692e+37}
fmt.Println(f.Skip) // <nil>
fmt.Println(f.Created.String()) // 1908-12-07 04:14:25.685339029 +0000 UTC
// Supported formats
// int, int8, int16, int32, int64,
// uint, uint8, uint16, uint32, uint64,
// float32, float64,
// bool, string,
// array, pointers, map
// time.Time // If setting time you can also set a format tag
// Nested Struct Fields and Embeded FieldsCustom FunctionsIn a lot of sitations you may need to use your own random function usage for your specific needs. If you would like to extend the usage of struct tags, generate function, available usages in the gofakeit server or gofakeit command sub packages. You can do so via the AddFuncLookup. Each function has their own lookup, if you need more reference examples you can look at each files lookups. // Simple
gofakeit.AddFuncLookup("friendname", Info{
Category: "custom",
Description: "Random friend name",
Example: "bill",
Output: "string",
Generate: func(r *rand.Rand, m *MapParams, info *Info) (interface{}, error) {
return RandomString([]string{"bill", "bob", "sally"}), nil
},
})
// With Params
gofakeit.AddFuncLookup("jumbleword", Info{
Category: "jumbleword",
Description: "Take a word and jumple it up",
Example: "loredlowlh",
Output: "string",
Params: []Param{
{Field: "word", Type: "string", Description: "Word you want to jumble"},
},
Generate: func(r *rand.Rand, m *MapParams, info *Info) (interface{}, error) {
word, err := info.GetString(m, "word")
if err != nil {
return nil, err
}
split := strings.Split(word, "")
ShuffleStrings(split)
return strings.Join(split, ""), nil
},
})
type Foo struct {
FriendName string `fake:"{friendname}"`
JumbleWord string `fake:"{jumbleword:helloworld}"`
}
var f Foo
gofakeit.Struct(&f)
fmt.Printf("%s", f.FriendName) // bill
fmt.Printf("%s", f.JumbleWord) // loredlowlhFunctionsAll functions also exist as methods on the Faker struct FileJSON(jo *JSONOptions) ([]byte, error)
