Question

我正在laravel开始测试

我用这个

创建了一个“.env.testing”文件

APP_NAME=myApp
APP_ENV=testing
APP_DEBUG=true
APP_LOG_LEVEL=debug
APP_URL=http://myApp.localhost

DB_CONNECTION=sqlite_testing

我在config / database.php文件的“connections”部分添加了这个

...
'sqlite_testing' => [
    'driver'   => 'sqlite',
    'database' => ':memory:',
    'prefix'   => '',
],
...

在phpunit.xml文件中，我添加了：

<env name="DB_CONNECTION" value="sqlite_testing" />

我创建了一个UserTest功能：

class UserTest extends TestCase
{

    public function setUp()
    {
        parent::setUp();
        Artisan::call('migrate');
        Artisan::call('db:seed');
    }

    public function tearDown()
    {
        parent::tearDown();
        Artisan::call('migrate:reset');
    }


    public function testCanAccessUserSpace()
    {
        $user = factory(User::class)->create();

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


        $response->assertStatus(200);
    }
}

但是当我运行测试时，我有这个：

ReflectionException: Class env does not exist

我的配置有什么问题？

感谢

Answer 1

运行phpunit时出现相同的错误：

ReflectionException：类env不存在

这是另一个问题，我已经安装了软件包 telescope ，而phpunit试图在测试时加载它：

ReflectionException: Class env does not exist
/var/www/html/mat2/vendor/laravel/telescope/src/Telescope.php:263
/var/www/html/mat2/vendor/laravel/telescope/src/Telescope.php:222

，依此类推。我已添加到phpunit.xml：

<env name="TELESCOPE_ENABLED" value="false"/>

之后，测试运行正常。
因此，可能与包装测试有关。

Answer 2

您需要将.env.testing重命名为.env，您已将APP_ENV设置为testing，因此无需将.env更改为{{1} }}

修改

还尝试使用.env.testing更新您的依赖项并重试，这不是常见的错误，因此它与您的测试环境设置相关

Answer 3

由于各种原因，引发此异常。在您的情况下，问题是在该函数内的特定操作顺序下的tearDown函数。您应该在底部调用父对象tearDown。所以这个：

public function tearDown()
{
    parent::tearDown();
    Artisan::call('migrate:reset');
}

应重构如下：

public function tearDown()
{
    Artisan::call('migrate:reset');
    parent::tearDown();
}

我怀疑原因是该应用实例在Illuminate\Foundation\Testing\TestCase内部被破坏了。这是Laravel 5.5中的代码：

if ($this->app) {
    foreach ($this->beforeApplicationDestroyedCallbacks as $callback) {
        call_user_func($callback);
    }

    $this->app->flush();

    $this->app = null;
}

Answer 4

如果您使用的是class PreferenceUtil { private var msharedPref: SharedPreferences? = null private var mEditor: Editor? = null companion object { private var sInstance: PreferenceUtils? = null fun getInstance(context: Context): PreferenceUtils { if (sInstance == null) { sInstance = PreferenceUtils(context) } return sInstance as PreferenceUtils } } constructor() constructor(mContext: Context?) { msharedPref = mContext?.getSharedPreferences(APP_PREF, MODE_PRIVATE) mEditor = mSettings?.edit() } // get Boolean value fun getValue(key: String, defValue: Boolean): Boolean { return msharedPref!!.getBoolean(key, defValue) } // set Boolean value fun setValue(key: String, value: Boolean) { mEditor!!.putBoolean(key, value) mEditor!!.apply() }，请将php artisan test --env=testing添加到您的TELESCOPE_ENABLED=false文件中，然后运行.env.testing。

Answer 5

就我而言，将TELESCOPE_ENABLED设置为false不能解决我的问题。我必须发出

php artisan config：clear

我使用Laravel 7。

Answer 6

此错误可能是由于在单元测试环境中打开望远镜引起的。

我将望远镜的默认行为更改为关闭，然后在我的import pygame import sys import random import math import time pygame.display.set_caption('Snake') pygame.font.init() game_running = True width = 400 height = 400 size = (width, height) window = pygame.display.set_mode(size) # our surface type pygame.display.set_caption("Snake Game by Nick Rinaldi") class Food: def __init__(self, block_size, surface, x_loc, y_loc): # pass in color and random_x/random_y. block size is a constant self.block_size = block_size self.surface = surface # green self.x_loc = x_loc self.y_loc = y_loc self.mask = pygame.mask.from_surface(self.surface) def draw(self, window): window.blit(self.surface, (self.x_loc, self.y_loc)) class Snake: def __init__(self, block_size, surface, x_loc, y_loc): self.block_size = block_size self.surface = surface # red self.x_loc = x_loc self.y_loc = y_loc self.body = [] self.direction = None self.velocity = 20 self.mask = pygame.mask.from_surface(self.surface) def draw(self, color, window, block_size): self.seg = [] self.head = pygame.Rect(self.x_loc, self.y_loc, block_size, block_size) pygame.draw.rect(window, color, self.head) if len(self.body) > 0: for unit in self.body: segment = pygame.Rect(unit[0], unit[1], block_size, block_size) pygame.draw.rect(window, color, segment) self.seg.append(segment) def add_unit(self): if len(self.body) != 0: index = len(self.body) -

您可以通过更新.env文件来将望远镜的默认值更改为false。

config/telescope.php

然后，您必须在.env文件中设置：/* |-------------------------------------------------------------------------- | Telescope Master Switch |-------------------------------------------------------------------------- | | This option may be used to disable all Telescope watchers regardless | of their individual configuration, which simply provides a single | and convenient way to enable or disable Telescope data storage. | */ 'enabled' => env('TELESCOPE_ENABLED', false), // Change from true to false here.。这样可以确保您不会在不需要的环境（例如生产和单元测试）中意外打开它。

在Laravel 5.5中测试：类env不存在
