Laravel 5 nullでgetContent（）でPHPUnitテストが失敗する

Question

Laravel 5のWebサイトでPHPUnitテストを実行するときにエラーが発生します。あなたは私にヒントを与えることができますか？既にcomposerとphpunitパッケージの両方を更新しました。

<? 

class ExampleTest extends TestCase 
{ 

    /** 
    * My test implementation 
    */ 
    public function testEncryptionIsIntelligent() 
    { 
     $this->see('Laravel 5'); 
     $this->visit('/'); 
     $this->visit('/auth/login'); 
     $this->type('test.admin@testsite.hu', 'email'); 
     $this->type('test', 'password'); 
     $this->press(''); 
     $this->seePageIs('/admin'); 
     $this->see('Welcome to the dashboard'); 
     $this->visit('/'); 
    } 
}

は私のテストファイルです。

$this->visit('/') 
    ->see('Laravel 5'); 

へ

$this->see('Laravel 5'); 
$this->visit('/'); 

あなたはlaravelのためにチェックする場所を認識していない何かのために最初にチェックしようとしている。この

Answer 1

変更。最初にページにアクセスし、内容を確認します。

私は考えチェーン行を次のように

$this->visit('/') 
     ->see('Laravel 5') 
     ->visit('/auth/login') 
     ->type('test.admin@testsite.hu', 'email') 
     ->type('test', 'password') 
     ->press('') 
     ->seePageIs('/admin') 
     ->visit('/') 
     ->see('Welcome to the dashboard');
