Laravel 9 测试用例 "The response is not a view."

Question

我是 Laravel 的新手，但我不明白如何在 TestCase 中获取视图。

目前我的测试用例中有这段代码 class :

<?php

namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
use App\Mail\ContactMail;
use App\Models\Contact;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Http;

class ContactTest extends TestCase
{
    use WithFaker;
    private $appName;

    protected function setUp(): void
    {
        parent::setUp();
        $this->setUpFaker();
    }

    /**
     * Test page HTTP status
     *
     * @return void
     */
    public function test_status()
    {
        $response = $this->get('/contact');
        $response->assertStatus(200);
    }
    
    /**
     * Test form post
     *
     * @return void
     */
    public function test_form_post()
    {
        $contactSubjects = Contact::all();
        $messageContent  = $this->faker->paragraphs(3, true);

        // Invalid request
        // $response = $this->post('/contact', [
        $response = $this->call('POST', 'contact', [
            'email' => $this->faker->text(), // invalid mail
            'object' => $this->faker->numberBetween(count($contactSubjects)+10, count($contactSubjects)+100), // Be sure we have a number greater than last contact object id
            'message_contact' => $messageContent
        ]);
        $response->assertViewIs('contact'); // RESPONSE IS NOT A VIEW

        // Valid request
        // $response = $this->post('/contact', [
        $response = $this->call('POST', 'contact', [
            'email' => $this->faker->email(), // valid mail
            'object' => $contactSubjects[rand(0, count($contactSubjects)-1)]->id, // Be sure we have a valid contact object ID
            'message_contact' => $messageContent
        ]);
        $response->assertViewIs('contact-validate'); // RESPONSE IS NOT A VIEW
    }
}

如您所见，我尝试使用 $response = $this->post('/contact', [ 和 $response = $this->call('POST', 'contact', [，但我遇到了同样的错误。

我想测试视图，因为我认为这是检测我的提交是否有错误的最准确方法，因为无论我是否有错误，呈现的视图都不相同。

这是我的控制器class :

<?php

namespace App\Http\Controllers;

use App\Http\Requests\StoreContactRequest;
use App\Models\Contact;
use Illuminate\Support\Facades\Mail;
use App\Mail\ContactMail;

class ContactController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $page = 'contact';

        return view($page, [
            'page' => $page,
            'objects' => Contact::all(),
            'error_sending' => false
        ]);
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \App\Http\Requests\StoreContactRequest  $request
     * @return \Illuminate\Http\Response
     */
    public function store(StoreContactRequest $request)
    {
        // Send mail
        try {
            Mail::to(config('mail.from.address'))->send(new ContactMail($request));
        }
        catch(\Throwable $e) {
            return view('contact', [
                'page' => 'contact',
                'objects' => Contact::all(),
                'error_sending' => 'Une erreur est survenue durant l\'envoie du mail. Merci de ré-essayer plus tard.<br><br>'.$e->getMessage()
            ]);
        }

        // Render view
        return view('contact-validate', [
            'page' => 'contact'
        ]);
    }
}

这是我的路线文件 (web.php) :

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ContactController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    $page = 'home';
    return view($page, ['page' => $page]);
});

Route::resource('/contact', ContactController::class);

我错过了什么？您需要更多代码才能回答吗？

您可以禁用异常处理以查看结果。

   /**
     * Test page HTTP status
     *
     * @return void
     */
    public function test_status()
    {
        $this->withoutExceptionHandling();
        $response = $this->get('/contact');
        $response->assertStatus(200);
    }
