Gofakeit 是一款Go語言編寫的隨機(jī)數(shù)據(jù)生成工具，使用更易用的接口設(shè)計，可滿足日常開發(fā)中絕大多數(shù)數(shù)據(jù)生成場景

Gofakeit讓您以更優(yōu)雅的姿勢生成測試數(shù)據(jù)。
Gofakeit內(nèi)置160+函數(shù)，同時也很方便自定義。

功能

160+內(nèi)置函數(shù)!!!
多個rand源
全局rand
支持struct tag
支持自定義函數(shù)
內(nèi)置http server
內(nèi)置command line tool
0依賴
高性能

安裝

????import?"github.com/brianvoe/gofakeit/v6"

Usage

快速開始

??import?"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()????//?USD

切換Random源Gofakeit有多個rand源，默認(rèn)是math.Rand，并且使用互斥鎖實現(xiàn)并發(fā)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，可以手動解除互斥鎖，注意這不是并發(fā)安全

??//?Uses?math/rand(Pseudo)?with?NO?mutext?locking
??//?More?performant?but?not?goroutine?safe.
??faker?:=?gofakeit.NewUnlocked(0)

全局設(shè)置rand 如果你需要全局替換rand源，只需要簡單設(shè)置即可：
```
??faker?:=?gofakeit.NewCrypto()
??gofakeit.SetGlobalFaker(faker)
```

Struct 生成Gofakeit可以為struct生成隨機(jī)數(shù)據(jù)，并且可以覆蓋所有基本類型，還可以使用tag定制數(shù)據(jù)

??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

自定義函數(shù) 你可以實現(xiàn)自己的生成函數(shù)，如果想要在http server和command line中使用，需要通過AddFuncLookup來實現(xiàn)自定義功能

??//?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

《酷Go推薦》招募：

各位Gopher同學(xué)，最近我們社區(qū)打算推出一個類似GoCN每日新聞的新欄目《酷Go推薦》，主要是每周推薦一個庫或者好的項目，然后寫一點這個庫使用方法或者優(yōu)點之類的，這樣可以真正的幫助到大家能夠?qū)W習(xí)到

新的庫，并且知道怎么用。

大概規(guī)則和每日新聞類似，如果報名人多的話每個人一個月輪到一次，歡迎大家報名！戳「閱讀原文」，即可報名

掃碼也可以加入 GoCN 的大家族喲～
