## 🚀 Cara Menjalankan Test

### 1. Setup Database Testing

Pastikan database testing sudah di-setup di `.env.testing` atau uncomment di `phpunit.xml`:

**Option A: Gunakan SQLite (Recommended untuk testing)**

Edit `phpunit.xml`:
```xml
<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>
```

**Option B: Gunakan Database MySQL terpisah**

Buat file `.env.testing`:
```env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=rikod_test
DB_USERNAME=root
DB_PASSWORD=
```

Buat database:
```bash
mysql -u root -p
CREATE DATABASE rikod_test;
```

### 2. Install Dependencies (jika belum)

```bash
composer install
```

### 3. Jalankan Migration untuk Testing

```bash
# Jika pakai MySQL
php artisan migrate --env=testing

# Jika pakai SQLite in-memory, tidak perlu (otomatis)
```

### 4. Jalankan Test

**Jalankan semua test Google Auth:**
```bash
php artisan test --filter=GoogleAuthTest
```

**Jalankan test spesifik:**
```bash
# Test signup saja
php artisan test --filter=test_successful_signup_with_google

# Test validation
php artisan test --filter=test_signup_fails

# Test login
php artisan test --filter=test_login_with_google
```

**Jalankan semua test aplikasi:**
```bash
php artisan test
```

**Dengan coverage:**
```bash
php artisan test --coverage
```

**Verbose output:**
```bash
php artisan test --filter=GoogleAuthTest -v
```

## 🛠️ Troubleshooting

### Error: "Database does not exist"

**Solution:**
```bash
# Create test database
mysql -u root -p
CREATE DATABASE rikod_test;

# Or use SQLite (edit phpunit.xml)
<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>
```

### Error: "Class 'Tests\Feature\UserCompany' not found"

**Solution:**
```bash
composer dump-autoload
```

### Error: "SQLSTATE[42S02]: Base table or view not found"

**Solution:**
```bash
# Run migrations for test database
php artisan migrate --env=testing

# Or clear cache
php artisan config:clear
php artisan cache:clear
```

### Tests are slow

**Solution:** Use SQLite in-memory database:
```xml
<!-- phpunit.xml -->
<env name="DB_CONNECTION" value="sqlite"/>
<env name="DB_DATABASE" value=":memory:"/>
```

## 📝 Adding More Tests

### Template untuk test baru:

```php
/**
 * Test description here
 */
public function test_my_new_test()
{
    // Arrange - setup data
    $payload = [
        'user_name' => 'Test User',
        'user_email' => 'test@gmail.com',
    ];

    // Act - execute the action
    $response = $this->postJson('/api/signupWithGoogle', $payload);

    // Assert - verify results
    $response->assertStatus(200)
        ->assertJson([
            'isSuccess' => true,
        ]);

    $this->assertDatabaseHas('tb_user', [
        'user_email' => 'test@gmail.com',
    ]);
}
```
