Laravel Collection Testing Helpers

This package adds several convenience methods to your Laravel collections to make assertions against them more fluent and readable.

Installation

You'll have to follow a couple of simple steps to install this package.

Downloading

Via composer:

$ composer require sven/laravel-collection-testing-helpers --dev

Or add the package to your development dependencies in composer.json and run composer update on the command line to download the package:

{
    "require-dev": {
        "sven/laravel-collection-testing-helpers": "^1.0"
    }
}

Usage

To use this package in your tests, you must first call the \Sven\LaravelCollectionTestingHelpers\Helpers::enable() method where you want to use the assertions. You may then use the methods directly on your collections:

<?php

use Sven\LaravelCollectionTestingHelpers\Helpers;
use Illuminate\Foundation\Testing\TestCase;

class ExampleTest extends TestCase
{
    public function test_collections()
    {
        Helpers::enable();
        
        collect(['apple', 'pear', 'banana'])
            ->assertContains('apple')
            ->assertNotContains('orange');
    }

    public function test_callable_filtering()
    {
        Helpers::enable();
        
        collect(['apple', 'pear', 'banana'])
            ->assertContains(fn ($fruit) => $fruit === 'pear')
            ->assertNotContains(fn ($fruit) => $fruit === 'kiwi');
    }

    public function test_keyed_collections()
    {
        Helpers::enable();
        
        collect([['name' => 'apple'], ['name' => 'pear'], ['name' => 'banana']])
            ->assertContains('name', 'apple')
            ->assertNotContains('name', 'grape');
    }
}
