Gofakeit 是一款Go语言编写的随机数据生成工具，使用更易用的接口设计，可满足日常开发中绝大多数数据生成场景
Gofakeit让您以更优雅的姿势生成测试数据。Gofakeit内置160+函数，同时也很方便自定义。
功能
160+内置函数!!! 多个rand源 全局rand 支持struct tag 支持自定义函数 内置http server 内置command line tool 0依赖 高性能
安装
import "github.com/brianvoe/gofakeit/v6"
Usage
快速开始
import "github.com/brianvoe/gofakeit/v6"
gofakeit.Name() // Markus Moen
gofakeit.Email() // alaynawuckert@kozey.biz
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() // USD切换Random源
Gofakeit有多个rand源，默认是math.Rand，并且使用互斥锁实现并发安全。// Uses crypto/rand(cryptographically secure) with mutext locking
faker := gofakeit.NewCrypto()
// Pass in your own random source
faker := gofakeit.NewCustom()如果你需要更高的性能，可以手动解除互斥锁，注意这不是并发安全
// Uses math/rand(Pseudo) with NO mutext locking
// More performant but not goroutine safe.
faker := gofakeit.NewUnlocked(0)全局设置rand 如果你需要全局替换rand源，只需要简单设置即可：
faker := gofakeit.NewCrypto()
gofakeit.SetGlobalFaker(faker)Struct 生成
Gofakeit可以为struct生成随机数据，并且可以覆盖所有基本类型，还可以使用tag定制数据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) //
fmt.Println(f.Created.String()) // 1908-12-07 04:14:25.685339029 +0000 UTC自定义函数 你可以实现自己的生成函数，如果想要在http server和command line中使用，需要通过
AddFuncLookup来实现自定义功能// 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: "int", 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) // loredlowlh
