JSON - Associaive Array assertions for PHPUnit

The intentions of this library is provide easy/intuitive assertions when we are a dealing with nested associative
arrays or JSON responses. It based on PHPUnit.

Installation

$ composer require --dev nordin74/associative-json-assertions

Usage

Add the trait use AssociativeAssertions\AssociativeArrayTrait or extend the class AbstractAssociativeArray and use the defined assertions AssociativeAssertions\AssociativeAssertions in your test case

<?php

use PHPUnit\Framework\TestCase;
use AssociativeAssertions\AssociativeArrayTrait;
use AssociativeAssertions\AssociativeAssertions as AA;

class MyTestCase extends TestCase
{
    use AssociativeArrayTrait;

    public function testSuccessfulJSONResponse()
    {
        $json =
                '{
                    "id"       : 11,
                    "extId"    : "111",
                    "isActive" : true,
                    "value"    : 12,
                    "firstname": "Seiya",
                    "surname"  : "unknown",
                    "height"   : 1.70,
                    "cloth"    : "Pegasus",
                    "deeper"   : {
                        "key1": "val1",
                        "key2": "2018-02-28 11:11:11",
                        "key3": ["val1", "val2", 11]
                    },
                    "optionalDateTimeStr": "2018-11-11 11:11:11"
                 }';

        $expected = [
            'id'        => AA::assertInt(),
            'extId'     => AA::assertDigit(),
            'isActive'  => AA::assertBoolean(),
            'value'     => 12,
            'firstname' => 'Seiya',
            'surname'   => AA::assertRegExp('~\w+known~'),
            'height'    => AA::assertFloat(),
            'cloth'     => AA::assertScalar(),
            'deeper'    => [
                'key1' => 'val1',
                'key2' => AA::assertDateTimeStr('Y-m-d H:i:s'),
                'key3' => function () {
                    $actual = func_get_args()[0];
                    $this::assertCount(3, $actual);
                }
            ],
            'optionalDateTimeStr' => AA::assertOptional(AA::assertDateTimeStr('Y-m-d H:i:s'))
        ];

        $this->assertAssociativeArray($expected, json_decode($json, true));
    }
}

You can define your own assertions. Example:

<?php
    [
        'key' => function () {
            $valueForBeingTested = func_get_args()[0];
            // Some awesome assertion
        }
    ];

If the assertion logic is complex you can also extend the class AssociativeAssertions.
