What you can do by reading this article

You will be able to do Unit Test using Mockery in Laravel.

• Since it was made quite a while ago, please feel free to point out mm

What is Mockery in the first place?

A PHP mock object framework that makes it easy to create mock with PHPUnit. https://readouble.com/mockery/1.0/ja/index.html

#Environment laravel 5.3 phpunit 5.7.3 Use mockery

Thing you want to do

• -I want to Mock an unimplemented static method called Test :: getInfo () and test it with phpunit.
• -I want to confirm at the same time through validation of laravel by sending post

The existing laravel validation is done in the store (IdRequest $ request) part of the code below. I’m doing a POST using $ this-> call () to test here. The situation that Test :: getInfo (), which is a part of the series of processing, is not implemented by external connection.

#Procedure

1. Routing settings

Route :: resource ('info','info @ store');

2. $ this-> call Controller call

<? php
namespace App \ Http \ Controllers;
use Illuminate \ Http \ Request;
use App \ Http \ Controllers \ Controller;
use App \ Http \ Requests \ Rlog \ IdRequest;
use App \ Http \ Models \ InfoLogic;
     
class InfoController extends Controller {
    public function store (IdRequest $ request) {
            $ info = new InfoLogic ($ request)
            $ info-> setInfo ();
            return $ info-> getInfo ();
    }
}

3. Validate with IdRequest

<? php
namespace App \ Http \ Requests;
 
use Illuminate \ Foundation \ Http \ FormRequest;
use Illuminate \ Contracts \ Validation \ Validator;

class IdRequest extends FormRequest
{
    public function authorize ()
    {
        return true;
    }
    public function rules ()
    {
        return [
            'id' =>' required | max: 255 | alpha_num',
        ];;
    }
}

4. Calling information from Model associated with ID

<? php
namespace App \ Models;

use Illuminate \ Database \ Eloquent \ Model;

class Infologic extends Model {
    public function __construct ($ request) {
        $ this-> id = $ request ['id'];
    }
    public function setInfo () {
        $ this-> info = Test :: getInfo ($ this-> id);
    }
    public function getInfo () {
        return $ this-> info;
    }
}

5. Call information from DB (Test :: getInfo ($ this-> id);, not implemented)

Mock this part.

6. Write test code based on the above

<? php
use Mockery as m;
use App \ Models \ InfoLogic;
class InfoValidateTest extends TestCase
{
    public function tearDown ()
    {
        parent :: tearDown ();
        m :: close ();
    }
    / **
     * @runInSeparateProcess
     * /
    public function test_id_name ()
    {
        // Create mock to get id
        $ mocker = m :: mock ('alias: App \ Models \ Test');
        $ return = 123456;
        $ argument ='yamada';
        $ mocker-> shouldReceive ('getInfo')-> andReturn ($ return);
        $ expected = 123456;
        $ actual = $ this-> call ('POST','info', array ('id' =>'tanaka'));
        $ this-> assertEquals ($ expected, $ actual);
    }
}

7. Test command execution

$ cd [Laravel project]
$ ./vendor/bin/phpunit tests / InfoValidateTest.php
