README

A package to facilitate the testing of classes/methods which uses ORM Repository and ORM Entity objects.

Installation

composer require --dev mgleska/repositorymock:"^1"

Features

1. Provides ready-made mocks for functions:

   • find()
   • findOneBy()
   • findBy()
     • by scalar value
     • by list of values
     • by object
   • save()
   • remove()

2. Allow to create mocks for Entity objects from array of values.

   • simple Entity (without relations)
   • multi-level Entity
     • Doctrine\ORM\Mapping\OneToOne
     • Doctrine\ORM\Mapping\ManyToOne
     • Doctrine\ORM\Mapping\OneToMany

3. Full compatibility with PHPUnit mock. An object of type RepositoryMock can be treated as a regular mock created by PHPUnit.
   For example, you can use $mockedRepository->method('myCustomMethod')->willReturn(...).

4. Provides the createFakeObject(string $className, array $objData) method which can be used to create Entity object for use in willReturn().
   Particularly useful for multi-level Entities and those where the id field has no setter (because it is autoincrement).

5. Provides the ability to create test scenarios for update/edit and create/delete actions.
   The mock for the save() function stores the data sent towards the database. Which gives the possibility to observe the "state of the database" after the tested operation $sut->action() is completed.

   • save() does:
     • update if entity exists
     • insert with autoincrement for id
   • than getStoreContent() method allow to make assertions on entities stored in database.

Usage

1. Mock for simple find().

// src/Service/SutService.php

class SutService
{
    public function __construct(
        private readonly Repository $repository,
    ) {
    }

    public function getFirst(): ?Entity
    {
        return $this->repository->find(1);
    }
}

// tests/Service/SutServiceTest.php

use RepositoryMock\RepositoryMockObject;
use RepositoryMock\RepositoryMockTrait;
...

class SutServiceTest extends TestCase
{
    use RepositoryMockTrait;

    private Sutservice $sut;

    private Repository|RepositoryMockObject $repository;

    protected function setUp(): void
    {
        $this->repository = $this->createRepositoryMock(Repository::class);

        $this->sut = new SutService(
            $this->repository,
        );
    }

    #[Test]
    public function getFirstFound(): void
    {
        $this->repository->loadStore([
            [ // values of selected properties of Entity
                'id' => 1,
                'name' => 'test',
            ],
        ]);

        $result = $this->sut->getFirst();

        $this->assertInstanceOf(Entity::class, $result);
    }

    #[Test]
    public function getFirstNotFound(): void
    {
        $this->repository->loadStore([
            [
                'id' => 22,
                'name' => 'test 22',
            ],
        ]);

        $result = $this->sut->getFirst();

        $this->assertNull($result);
    }
}
