Writing a factory in Laravel.

By using the factory we can generate some fake data for the testing

<?php

/** @var \Illuminate\Database\Eloquent\Factory $factory */

use App\Product;

use Faker\Generator as Faker;

$factory->define(Product::class, function (Faker $faker) {

    return [

        'name' => $faker->name, // generate a random name 

        'brand'=>$faker->randomElement, //generate a random elemtn

        'description'=> $faker->text, // bunch of text

        'hsn'=> $faker->numberBetween($min = 1000, $max = 9000), 

// number between 1000 -90000 to 9000

        'tax'=> $faker->randomElement(['18%','12%','5%','NILL','28%']) 

// pic a value from this array 

    ];

});.
