Fake Data Generator for Golang

Generates random data compatible with Postman dynamic variables.

Ddosify open-source load testing tool uses this faker library for dynamic variables.

Note: This library uses jaswdr/faker. There are also some constants from faker-js to generate random values.

Usage

package main

import (
	"fmt"

	"github.com/ddosify/go-faker/faker"
)

func main() {
	faker := faker.NewFaker()
	fmt.Println(faker.RandomBankAccountIban()) // DE15534524466712768735
	fmt.Println(faker.RandomMimeTypes())       // audio/mpeg
	fmt.Println(faker.RandomAdjective())       // open-source
	fmt.Println(faker.RandomAbstractImage())   // http://placeimg.com/640/480/abstract
	fmt.Println(faker.RandomCountryCode())     // GF
	fmt.Println(faker.RandomUsername())        // Charlie.Hansen
	fmt.Println(faker.RandomSemver())          // 3.5.3
}
