How can I test a store function with Laravel and Mockery - laravel

Question

I want to test a repository pattern in Laravel 5.6 using PHPUnit and Mockery.
This is my code:
// PackageControllerTest.php
namespace Tests\Feature;
use Tests\TestCase;
use App\Contracts\PackageInterface;
use App\Http\Controllers\PackageController;
use Illuminate\Database\Eloquent\Collection;
class PackageControllerTest extends TestCase
{
protected $mock;
protected $target;
public function setUp()
{
parent::setUp();
parent::initDatabase();
$this->mock = $this->initMock(PackageInterface::class);
$this->target = $this->app->make(PackageController::class);
}
public function testIndex()
{
$expected = new Collection([
['name' => 'Name 1', 'html_url' => 'HTML URL 1'],
['name' => 'Name 2', 'html_url' => 'HTML URL 2'],
['name' => 'Name 3', 'html_url' => 'HTML URL 3'],
]);
$this->mock
->shouldReceive('getAllPackages')
->once()
->andReturn($expected);
$actual = $this->target->index()->packages;
$this->assertEquals($expected, $actual);
}
public function testUpdate()
{
//
}
public function tearDown()
{
parent::resetDatabase();
$this->mock = null;
$this->target = null;
}
}
// PackageControllerTest.php
...
public function index()
{
$packages = $this->package->getAllPackages();
return view('package.index', compact('packages'));
}
public function update($package_id)
{
$package = $this->package->updatePackage($package_id);
return redirect()->back();
}
// PackageRepository.php
...
public function getAllPackages()
{
$packages = $this->package->all();
return $packages;
}
public function updatePackage($package_id)
{
$package = $this->package->find($package_id);
$package->description = $this->request->description;
$package->save();
return $package;
}
The part of "testIndex()" works.
But next, I want to test the part of "testUpdate()".
How can I do?
Please help, thanks.

like this
$this->mock
->shouldReceive('updatePackage')
->with(1)
->once()
->andReturn($expected);
$actual = $this->target->update(1);
$this->assertRedirect('edit page url');
or
use DatabaseTransactions in top of class
$id = DB::table('your_table')->insertGetId(['description' => 'old'])
request()->set('description', 'test');
$actual = $this->target->update(id);
$this->assertDatabaseHas('your_table', [
'id' => $id,
'description' => 'test'
]);
