如何为后端控制器执行单元测试

Question

我希望通过单元测试来测试我的后端控制器是否正常运行，这样我就不必在更改内容时手动检查它们。

不幸的是，无论我尝试什么，我都找不到 404。

我的phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="../../../tests/bootstrap.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false"
         syntaxCheck="false"
>
    <testsuites>
        <testsuite name="ExitControl.Administration test suite">
            <directory>./tests</directory>
        </testsuite>
    </testsuites>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="SESSION_DRIVER" value="array"/>
    </php>
</phpunit>

我试图访问后端的测试url

public function setUp() 
{
    parent::setup();

    $user = User::create([
        'email' => 'tester@admin.com',
        'login' => 'tester',
        'password' => 'test',
        'password_confirmation' => 'test',
        'send_invite' => false,
        'is_activated' => true,            
    ]);

    $user->is_superuser = true;
    $user->save();

    $user = BackendAuth::authenticate([
        'login' => 'tester',
        'password' => 'test'
    ], true);
}

public function testCreateIndexView()
{

    $controller = $this->getController();

    $configUrl = config('app.url') . '/' . 
                 config('cms.backendUri') . '/';

    $url = preg_replace('/([^:])(\/{2,})/', '/', 
            $configUrl . 
            str_replace(['controllers\', '\'], ['', '/'], 
            strtolower(get_class($controller))));

    $result = $this->get($url);

    dd($result);// shows a 404
}

dd()的输出；

我也试过直接调用controller，但是很多正常请求填充的值在BackendController中都是空的

我需要更改什么设置才能测试我的后端控制器？

Answer 1

要测试您的控制器是否 运行 您需要将执行上下文设置为后端并 运行 后端服务提供商。

即便如此，您仍需要为您可以使用的内存数据库设置管理员测试用户，否则控制器将尝试将您重定向到登录页面。

use BackendAuth;
use PluginTestCase;
use Backend\Models\User;
use Backend\Classes\Controller;
use MyAuthor\MyPlugin\Controllers\MyController;

class BasicBackendControllerTest extends PluginTestCase
{

    public function setUp() 
    {
        parent::setup();

        $user = User::create([
            'email' => 'tester@admin.com',
            'login' => 'tester',
            'password' => 'test',
            'password_confirmation' => 'test',
            'send_invite' => false,
            'is_activated' => true,            
        ]);

        $user->is_superuser = true;
        $user->save();

        $user = BackendAuth::authenticate([
            'login' => 'tester',
            'password' => 'test'
        ], true);
    }

    public function testCreateIndexView()
    {
        // default this will be at front-end. This needs to be set to 
        // back-end so the service provider we will load will load up 
        // the backend settings.
        app()->setExecutionContext('back-end');

        // registering and running the service provider
        $provider = app()->register('\Backend\ServiceProvider');
        $provider->boot();

        // the magic happens here that allows a controller to be run.
        $provider->register();

        // retrieve the controller instance from child class
        $controller = new MyController();

        $result = $controller->run('index');

        $this->assertEquals(200, $result->status());
    }
}
