[2.x] Implementation to the `at` method

[Tiskiel]

What:

• [ ] Bug Fix
• [x] New Feature

Description:

Implementation of the at method. This will allow you to target an index or key on an iterable and apply other expectation methods to the value. It provides better readability and works on nested arrays.

Example below:

it('ensures it work with nested array', function () {
    $nestedArray = [
        [1, 2, 3],
        ['foo' => 'bar', 'john' => 'doe'],
    ];

    expect($nestedArray)
        ->at(0)->at(1)->toBe(2)
        ->and($nestedArray)
        ->at(1)->foo->toBe('bar');
});

Hi there,

I have implemented the dot notation as spoked above.

Here is an example :

it('ensures it work with dot notation', function () {
    $nestedDictionary = [
        'foo' => [
            'bar' => [
                'john' => 'doe',
            ],
        ],
    ];

    expect($nestedDictionary)
        ->at('foo.bar.john')->toBe('doe');
});

No plans for this.
