Testing Feature

1. Make Feature Test and Unit Test

   php artisan make:test NoteTest
   php artisan make:test NoteUnitTest --unit
   

2. Update NoteTest Feature with this code

   <?php
   
   namespace Tests\Feature;
   
   use Illuminate\Foundation\Testing\RefreshDatabase;
   use Tests\TestCase;
   use App\Models\Note;
   use App\Models\User;
   
   class NoteTest extends TestCase
   {
       use RefreshDatabase;
       protected $user; 
       
       protected function setUp(): void
       {
           parent::setUp();
           $this->user = User::factory()->create();
           // var_dump("awal");
       }
   
       protected function tearDown(): void
       {
           parent::tearDown();
           unset($this->user);
           // var_dump("akhir");
       }
   
       /** 
       * @test
       * @group test1
       */
       public function a_note_can_be_created()
       {
           // var_dump("create");
           $this->withoutExceptionHandling();
           $response = $this->actingAs($this->user)->post('/notes', [
               'note' => 'Test Note'
           ]);
   
           $response->assertRedirect('/notes');
           $this->assertCount(1, Note::all());
       }
   
       /** 
       * @test
       * @group test1
       */
       public function a_note_can_be_updated()
       {
           // var_dump("update");
           $this->withoutExceptionHandling();
           $this->actingAs($this->user)->post('/notes', [
               'note' => 'Test Note'
           ]);
   
           $note = Note::first();
   
           $response = $this->actingAs($this->user)->put('/notes/' . $note->id, [
               'note' => 'Updated Note'
           ]);
   
           $response->assertRedirect('/notes/' . $note->id);
           $this->assertEquals('Updated Note', Note::first()->note);
       }
   
       /** 
       * @test
       * @group test2
       */
       public function a_note_can_be_deleted()
       {
           // var_dump("delete");
           $this->withoutExceptionHandling();
           $this->actingAs($this->user)->post('/notes', [
               'note' => 'Test Note'
           ]);
   
           $note = Note::first();
   
           $response = $this->actingAs($this->user)->delete('/notes/' . $note->id);
   
           $response->assertRedirect('/notes');
           $this->assertCount(0, Note::all());
       }
   }
   

3. Update Note Unit Test with this code

   <?php
   
   namespace Tests\Unit;
   
   use Illuminate\Foundation\Testing\RefreshDatabase;
   use Tests\TestCase;
   use App\Models\Note;
   
   class NoteUnitTest extends TestCase
   {
       use RefreshDatabase; 
   
       /** @test */
       public function it_can_create_a_note()
       {
           $noteData = [
               'note' => 'This is a test note.'
           ];
   
           $note = Note::create($noteData);
   
           $this->assertInstanceOf(Note::class, $note);
           $this->assertEquals($noteData['note'], $note->note);
       }
   
       /** @test */
       public function it_requires_note_field()
       {
           // Example Fail
           // $note = Note::create(['note' => null]);
           // $this->assertNull($note);
   
           // Example Pass
           $note = Note::create(['note' => 'is not null']);
           $this->assertNotNull($note);
       }
   }
   

4. Run php artisan test for testing
