Laravel OneToOneのテストメソッドの書き方

– 親テーブルの方にテストケースを書く
– modelのmass asignmentは忘れがちなので注意

BookManagementTest.php

public function test_a_new_author_is_automatically_added(){
        $this->post('/books', [
            'title' => 'Cool Title',
            'author' => 'Victor'
        ]);

        $book = Book::first();
        $author = Author::first();

        $this->assertCount(1, Author::all());
        $this->assertEquals($author->id, $book->book_id);
    }

Author.php

public function setAuthorAttribute($author){
    	$this->attributes['author_id'] = Author::firstOrCreate([
    			'name' => $author,
    	]);
    }

$ phpunit –filter test_a_new_author_is_automatically_added

tests/Unit/AuthorTest.php

namespace Tests\Unit;

// use PHPUnit\Framework\TestCase;
use Tests\TestCase;
use Illuminate\Foundation\Testing\RefreshDatabase;
use App\Author;

class ExampleTest extends TestCase
{
	use RefreshDatabase;
    public function test_a_dob_is_nullable(){
    	Author::firstOrCreate([
    			'name' => 'John Doe'
    	]);

    	$this->assertCount(1, Author::all());
    }
}

author migration file

Schema::create('authors', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->timestamp('dob')->nullable();
            $table->timestamps();
        });

public function test_a_new_author_is_automatically_added(){
        $this->withoutExceptionHandling();
        $this->post('/books', [
            'title' => 'Cool Title',
            'author' => 'Victor'
        ]);

        $book = Book::first();
        $author = Author::first();
        
        $this->assertEquals($author->id, $book->author_id);
        $this->assertCount(1, Author::all());
    }

$ php artisan make:test BookTest –unit

>>> \Schema::getColumnListing(‘books’);
=> [
“id”,
“title”,
“author”,
“author_id”,
“created_at”,
“updated_at”,
]

Book.php

protected $fillable = ['title', 'author','author_id'];

    public function path(){
    	return '/books/' . $this->id;
    }

public function test_an_author_id_is_recorded()
    {
    	Book::create([
    		'title' => 'Coolest title',
    		'author' => '',
    		'author_id' => 1,
    	]);

    	$this->assertCount(1, Book::all());
    }

$ phpunit –filter test_an_author_id_is_recorded
OK (1 test, 1 assertion)

BooksController.php

rotected function validateRequest(){
    	return request()->validate([
    		'title' => 'required',
    		'author_id' => 'required',
    	]);
    }

Book.php

public function setAuthorIdAttribute($author){
    	$this->attributes['author_id'] = (Author::firstOrCreate([
    			'name' => $author,
    	]))->id;
    }

$ phpunit –filter test_a_new_author_is_automatically_added
OK (1 test, 2 assertions)

ぐううう

### 全てのmethodをテストするとき
just run phpunit
$ phpunit

### private function

$response = $this->post('/books', [
            'title' => 'Cool Title',
            'author_id' => 1
        ]);

$response = $this->post('/books',$this->data());
private function data() : array{
        return [
            'title' => 'Cool Title',
            'author_id' => 1
        ];
    }

### array_merge

public function test_a_author_is_require(){

        $response = $this->post('/books', array_merge($this->data(), ['author_id'=> '']));

        $response->assertSessionHasErrors('author_id');

    }

OneToOneのテストメソッドでも基本は同じ
