Test case

class MakeTest extends \PHPUnit\Framework\TestCase
{
    public function testCheck()
    {
        static::assertTrue(true);
    }
}

{
  "require": {
    "php": ">=7.1.3",
  },
  "require-dev": {
    "phpunit/phpunit": "~7.0"
  },
  "autoload": {

}

Date time

Laravel

Validation

$data = [
    'name' => 'Daniel'
];

$rule = [
    'name'  => 'required'
];

$v = $this->app['validator']->make(
        $data,
        $rule
    );

static::assertTrue($v->passes());

Console Command

This way can check output.

$this->artisan('command', [
            'param1' => 'value1',
            '--param2' => 'value2',
        ]);
$output = Artisan::output();

static::assertContains('output wording', $output);

Command tester

This way can use debug and output.

$command = new \App\Console\Commands\CommandClass();
$command->setLaravel($this->app);

$tester = new \Symfony\Component\Console\Tester\CommandTester($command);
$tester->execute([
            'param1' => 'value1',
            '--param2' => 'value2',
        ]);
$output = $tester->getDisplay();
self::assertContains('Wording that expected.', $output);

Controller

Two ways to test controller

$response = $this->get(action('Controller@edit', [$retailer->id]))
            ->assertSuccessful();

$this->get(route("route.name"))
            ->assertSuccessful();

Middleware

Middleware class

namespace App\Http\Middleware;

use Closure;

class Sample
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request $request
     * @param  \Closure $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        return $next($request);
    }
}

Test case

use App\Http\Middleware\Sample;
use Mockery;

class SampleMiTest extends \TestCase
{
    public function test_sample_middleware()
    {
        $response = $this->faker->md5;

        $request = Mockery::mock(\App\Http\Requests\Request::class);

        $request->shouldReceive('test')
            ->once()
            ->andReturn($response);

        $middleware = new Sample();

        $result = $middleware->handle($request, function ($r) {
            return $r->test();
        });

        $this->assertSame($response, $result);
    }
}

Model

Code

$productProvider = new Product;

$product = $productProvider->where('id', 1)->first();
 
$product->name = 'name';

$productNumber = $product->number;

$product->save();

Test


$model = \Mockery::mock(Product::class);

$model->shouldReceive('where')
    ->once()
    ->andReturnSelf();

$model->->shouldReceive('first')
    ->once()
    ->andReturnSelf();

$model->shouldReceive('setAttribute')
    ->once();

$model->shouldReceive('getAttribute')
    ->with('number')
    ->andReturn($this->faker->numberBetween(1,10));

$model->shouldReceive('save')
    ->once();

Abstract Class

Abstract Class

abstract class AbstractClass
{
    public function method()
    {
        return $this->property;
    }
}

Test case

class SampleMiTest extends \TestCase
{
    private function getSubclass($property)
    {
        $subclass = new class($property) extends AbstractClass
        {
            protected $property;

            public function __construct($property)
            {
                $this->property = $property;
            }
        };

        return $subclass;
    }

    public function testMethod()
    {
        $property = 'string';

        $sub = $this->getSubclass($property);

        static::assertSame($property, $sub->getMethod());
    }
}

Request

Test Code

// Create request and set attribute
use Illuminate\Http\Request;

$request = new Request;
$request->attribute = 'value';

// Mockery request
$request = Mockery::mock(\Illuminate\Http\Request::class);
$request->shouldReceive('hasSession')
    ->andReturn(true)
    ->shouldReceive('getSession')
    ->andReturn(md5(''))
    ->shouldReceive('get')
    ->andReturn('test')
    ->shouldReceive('has')
    ->andReturn(false)
    ;

// Mockery request with upload file

$expected = [
    'path' => sprintf('csv-storage://%s/%s', $this->getUploadPath(), __FILE__),
    'size' => 0,
    'mimeType' => $csv ? 'text/csv' : 'application/pdf'
]

$uploadedFile = Mockery::mock(\Illuminate\Http\UploadedFile::class);
$uploadedFile
    ->shouldReceive('hashName')
    ->andReturn(__FILE__)
    ->shouldReceive('getMimeType')
    ->andReturn($expected['mimeType'])
    ->shouldReceive('getSize')
    ->andReturn($expected['size']);

$request = Mockery::mock(\Illuminate\Http\Request::class);
$request->shouldReceive('hasFile')
->andReturn(true)
->shouldReceive('file')
->andReturn($inputFile);


// MOckery request with getting file
$file = new \stdClass();
$file->name = 'name';
$file->uuid = 'uuid';
$file->mimeType = 'mimeType';
$file->size = 100;
$file->isImage = $image;

if ($image) {
    $file->originalImageInfo = new \stdClass();
    $file->originalImageInfo->height = 100;
    $file->originalImageInfo->width = 100;
}

$requestFile = json_encode($file);
$request = Mockery::mock(Request::class);
$request->shouldReceive('get')->andReturn($requestFile);

app() helper

test code


$this->app->bind(ClassName::class, function () {
    return Mockery::mock()
            ->shouldReceive('setMethod')->with('x')->once()
            ->shouldReceive('getMethod')->once()->andReturn('y')
            ->getMock();
});

Filesystem (AwsS3Adapter)

use Aws\S3\S3Client;
use League\Flysystem\AwsS3v3\AwsS3Adapter;
use League\Flysystem\Filesystem;

$filename = 'filename';
$content = 'content';
$client = new S3Client([
    'credentials' => [
        'key'    => 'aws-key',
        'secret' => 'aws-secret'
    ],
    'region' => 'aws-region',
    'version' => 'latest|version',
]);

$adapter = new AwsS3Adapter($client, 'aws-s3-bucket');

$filesystem = new Filesystem($adapter);

return $filesystem->write($filename, $content, [
    'Metadata' => [
        'mode' => 0666 + 0100000,
        'gid' => 1000,
        'uid' => 1000
    ]
]);

Test private method

Using ReflectionClass to test a private or protect method in a class2.

$reflection = new \ReflectionClass(get_class($object));
$method = $reflection->getMethod($methodName);
$method->setAccessible(true);
$method->invoke($object, $args);

Test event and listener

In EventServiceProvider

EventClass::class => [
    Listener1Class::class,
    Listener2Class::class,
    Listener3Class::class,
],

Test case

$event = new EventClass();

$this->registerListenersInApp([
    Listener1Class::class,
    Listener2Class::class,
    Listener3Class::class
]);

event($event);

Mock external static methods 3


namespace Library;


class SomeClass
{
    public static function work()
    {
        return time();
    }
}

class Foo
{
    public function __construct()
    {
    }

    public function connect()
    {
        return SomeClass::work();
    }
}

Aliasing and Overloading

Alias mocks create a class alias with the given classname to stdClass and are generally used to enable the mocking of public static methods. Expectations set on the new mock object which refer to static methods will be used by all static calls to this class. 4

Test case

namespace Tests\Unit;
class TestClass extends TestCase
{
    public function test_connect()
    {
        $ab = \Mockery::mock('overload:Library\SomeClass')
            ->shouldReceive('work')
            ->once()
            ->andReturn(true);


        $foo = new Foo();
        static::assertTrue($foo->connect());
    }
}
