Question

我正在尝试抛出一个新的自定义异常，并编写测试以确保它实际被抛出。我在以下位置创建了一个新的异常App \ Exceptions \ AgreementsNotSignedException.php

<?php

namespace App\Exceptions;

class AgreementsNotSignedException extends \Exception {}

我订单的'结帐'方法如下：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\Exceptions\AgreementsNotSignedException as AgreementsNotSignedException;

class Order extends Model
{
    public function checkout() 
    {
        throw new AgreementsNotSignedException("User must agree to all agreements prior to checkout.");
    }
}

我失败的基本测试如下：

<?php

use App\Order;
use App\Exceptions\AgreementsNotSignedException;

use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class OrderTest extends TestCase {
     /** @test * */
    function it_does_not_allow_the_user_to_checkout_with_unsigned_contracts()
    {
        $exceptionClass = get_class(new App\Exceptions\AgreementsNotSignedException());
        $this->setExpectedException(
            $exceptionClass, 'User must agree to all agreements prior to checkout.'
        );

        try {
            $this->order->checkout();
        } catch (App\Exceptions\AgreementsNotSignedException $exception) {
            $this->assertNotEquals($this->order->status, "completed");
        }
    }
}

消息spit out''失败断言类型异常“App \ Exceptions \ AgreementsNotSignedException”被抛出。'。但是，我可以通过xdebug验证异常确实被捕获。正如Jeff在评论中所说的那样，它似乎是一个FQN问题，因为这样做会使测试通过：

 /** @test * */
function it_does_not_allow_the_user_to_checkout_with_unsigned_contracts()
{
    $exceptionClass = get_class(new App\Exceptions\AgreementsNotSignedException());
    $this->setExpectedException(
            $exceptionClass, 'User must agree to all agreements prior to checkout.'
        );

    throw new App\Exceptions\AgreementsNotSignedException('User must agree to all agreements prior to checkout.');
}

我会一直在改变FQN，但任何指导都会很棒。

Answer 1

刚遇到同样的问题并找到了解决方案，根据源代码，不推荐使用PhpUnit的$this->setExpectedException()方法。

* * @since Method available since Release 3.2.0 * @deprecated Method deprecated since Release 5.2.0 */ public function setExpectedException($exception, $message = '', $code = null) {

我使用 $this->expectException(MyCustomException::class) 代替了它。

Answer 2

尝试：

$this->setExpectedException(
            'App\Exceptions\AgreementsNotSignedException, 'User must agree to all agreements prior to checkout.'
        );

而不是：

$exceptionClass = get_class(new App\Exceptions\AgreementsNotSignedException());
        $this->setExpectedException(
            $exceptionClass, 'User must agree to all agreements prior to checkout.'
        );

PHPUnit与Laravel 5.2无法找到自定义异常
