当我想在Laravel 5网站上运行PHPUnit测试时，我收到了错误消息。你能给我一个提示吗？已经更新了composer和phpunit包。
PHPUnit 5.2.12 by Sebastian Bergmann and contributors.
Starting test 'Warning'.
W
Starting test 'ExampleTest::testEncryptionIsIntelligent'.
PHP Fatal error: Call to a member function getContent() on null in /var/www/hu.testsite/vendor/laravel/framework/src/Illuminate/Foundation/Testing/InteractsWithPages.php on line 187
[Symfony\Component\Debug\Exception\FatalErrorException]
Call to a member function getContent() on null
这是我的测试文件：
<?
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('/');
}
}

帮助会很感激。
答案 0 :(得分：2)
改变这个：
$this->see('Laravel 5');
$this->visit('/');
到
$this->visit('/')
->see('Laravel 5');
您正在尝试首先检查laravel不知道在哪里检查的内容。首先访问页面，然后检查内容。
我会将这些行链接如下：
$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');
