laravelでテストコードを書いてみた。

1, テストコードをartisanで自動生成。

php artisan make:test HelloTest

1	php artisan make:test HelloTest

tests/Feature/HelloTest.phpが生成される。

<?php

namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;

class HelloTest extends TestCase
{
    /**
     * A basic feature test example.
     *
     * @return void
     */
    public function testExample()
    {
        $response = $this->get('/');

        $response->assertStatus(200);
    }
}

<?php

namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;

use Illuminate\Foundation\Testing\WithFaker;

use Tests\TestCase;

class HelloTest extends TestCase

{

/**

* A basic feature test example.

* @return void

public function testExample()

{

$response = $this->get('/');

$response->assertStatus(200);

}

2, テストコードを実行してみる。vendorフォルダ以下を実行するのって初めてかも？

vendor/bin/phpunit tests/Feature/HelloTest.php

OK (1 test, 1 assertion)

vendor/bin/phpunit tests/Feature/HelloTest.php

OK (1 test, 1 assertion)

3, テスト内容を増やしてみる。

    public function testIndex()
    {
        $this->get('/') // トップページに
        ->assertSeeText('Hello'); // 文字列 Helloはあるか？
    }

public function testIndex()

{

$this->get('/') // トップページに

->assertSeeText('Hello'); // 文字列 Helloはあるか？

}

4, 実行すると当然エラーになる。

トップページを書き換えて、Helloという文字列を入れると、OKとなる。
う～ん、これ一項目ずつ書いてくと、大変な量になりそう…。
