README

mock instance's properties via Mockery's overload keyword

installation

use composer to install mockery-overload-properties

$ composer require --dev hermeslin/mockery-overload-properties

test legacy sample code

under the example folder, you can see the sample code taht we want to test:

1. User.php
2. Vip.php

and you'll find the hard dependencies in Vip.php.

hard dependencies are not a big deal, you can use Mockery's overload keyword to mock User instance easily, but it difficult to mock User instance properties when User set the properties on its __construct phase.

test case

under the tests folder, there are two test cases here:

1. LegacyCodeFailTest.php
2. LegacyCodeSuccessTest.php

see tests\LegacyCodeSuccessTest.php will show you how to use mockery-overload-properties to mock User

    /**
     * @test
     */
    public function notVipUserBonusShouldCorrect()
    {
        $properties = [
            'id' => 2,
            'isVip' => false,
            'rank' => 99
        ];
        $user = mop::mock('\User', $properties);

        // bounus should be 149
        $bunus = 100 * 0.5 + 99;

        $vip = new Vip;
        $this->assertEquals($bunus, $vip->bonus($userId = 2));
    }

when mock instance whith properties, you still can use Expectation Declarations from Mockery to test you code.

    /**
     * @test
     */
    public function notVipUserBonusShouldCorrect()
    {
        $properties = [
            'id' => 2,
            'isVip' => false,
            'rank' => 99
        ];
        $user = mop::mock('\User', $properties);

        // Expectation
        $user->shouldReceive('name_of_method');
            ->with($arg1, $arg2, ...);
            ->andReturn($value);

        // etc...
    }
