Warning

With the release of Laravel 10, there is an official Pennant package that can replace the current one. So consider upgrading to it.

Experiment

An A/B Testing suite for Laravel, which allows multiple experiments.

Installation

Download using Composer:

$ composer require orchid/experiment

Base Usage

Your cache driver will be used by default.

use Orchid\Experiment\Experiment;

$experiment = new Experiment();

// Distribution
$ab = $experiment->start([
    'A' => 1,
    'B' => 1,
]); // A or B

The experiment is transmitted in an array, where the keys are the names, and the values are the required ratios. For example, if you specify two values containing A -> 50 and B -> 100, there will be 50 users with the value A, then there will be 100 users with the value B. It allows us to define how the testing will be distributed clearly.

use Orchid\Experiment\Experiment;
use Illuminate\Support\Facades\Cache;

$storage = Cache::store('redis');
$experiment = new Experiment('my-key', $storage);

$ab = $experiment->start([
    'A' => 50,
    'B' => 100,
]); // A or B

You can also install via your request:

http:://example.com?my-key=A

Cookie

I recommend putting this on middleware and immediately install a cookie using.

namespace App\Http\Middleware;

use Closure;
use Orchid\Experiment\Experiment;

class Experiments
{
    
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     *
     * @return mixed
     * @throws \Exception
     */
    public function handle($request, Closure $next)
    {
        $experiment = new Experiment('AB');

        $experiment->startAndSaveCookie([
            'A' => 50,
            'B' => 50,
        ]);
        
        return $next($request);
    }
}

It allows you to transfer data to Google analytics and similar services using javascript.

alert( document.cookie );

Laravel encrypts all cookies by default, so do not forget to specify your key in the exceptions app/Http/Middleware/EncryptCookies.php:

namespace App\Http\Middleware;

use Illuminate\Cookie\Middleware\EncryptCookies as Middleware;

class EncryptCookies extends Middleware
{
    /**
     * The names of the cookies that should not be encrypted.
     *
     * @var array
     */
    protected $except = [
        'AB'
    ];
}

Blade

If you want to use the blade, you still must install the middleware after this call is as example:

@experiment('my-key', 'A')
    <button>Click me</button>
@else
    <button>Push me</button>
@endexperiment
