laravel - PHPUnit:预期状态代码 200，但使用 Laravel 收到 419

Question

我想测试删除方法，但我没有从 PHPUnit 获得预期的结果。运行测试时我收到此消息:

 Expected status code 200 but received 419. Failed asserting that false is true.
 /vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestResponse.php:77
 /tests/Unit/CategoriesControllerTest.php:70

Laravel 版本:5.5

感谢您的帮助!

Controller 构造函数:

public function __construct()
{
    $this->middleware('auth');

    $this->middleware('categoryAccess')->except([
        'index',
        'create'
    ]);
}

Controller 方法:

public function destroy($categoryId)
{
    Category::destroy($categoryId);

    session()->flash('alert-success', 'Category was successfully deleted.');

    return redirect()->action('CategoriesController@index');
}

类别访问中间件:

public function handle($request, Closure $next)
{
    $category = Category::find($request->id);

    if (!($category->user_id == Auth::id())) {
        abort(404);
    }

    return $next($request);
}

类别模型:

protected $dispatchesEvents = [
    'deleted' => CategoryDeleted::class,
];

事件监听器

public function handle(ExpensesUpdated $event)
{
    $category_id = $event->expense->category_id;

    if (Category::find($category_id)) {
        $costs = Category::find($category_id)->expense->sum('cost');

        $category = Category::find($category_id);

        $category->total = $costs;

        $category->save();
    }
}

PHPUnit删除测试:

use RefreshDatabase;

protected $user;

public function setUp()
{
   parent::setUp();
   $this->user = factory(User::class)->create();
   $this->actingAs($this->user);
}

/** @test */
public function user_can_destroy()
{
    $category = factory(Category::class)->create([
        'user_id' => $this->user->id
    ]);

    $response = $this->delete('/category/' . $category->id);

    $response->assertStatus(200);

    $response->assertViewIs('category.index');
}

解决方案:当您缓存配置文件时，您可以通过运行 php artisan config:clear 来解决此问题。

说明:之所以可以解决该问题，是因为 PHPUnit 将使用缓存的配置值，而不是测试环境中定义的变量。因此，APP_ENV 未设置为测试，并且 VerifyCsrfTokenMiddleware 将抛出 TokenMismatchException(状态代码 419)。

当 APP_ENV 设置为测试时，不会抛出此异常，因为 VerifyCsrfTokenMiddleware 的 handle 方法会检查您是否正在运行单元使用 $this->runningUnitTests() 进行测试。

建议不要在开发环境中缓存您的配置。当您需要在运行单元测试的环境中缓存配置时，您可以在 TestCase.php 中手动清除缓存:

use Illuminate\Support\Facades\Artisan; 

public function createApplication()
{
    ....
    Artisan::call('config:clear')
    ....
}

基于 https://github.com/laravel/framework/issues/13374#issuecomment-239600163 的示例
