Laravel 5.5测试 - 调用未定义的方法:: see()

Question

我运行phpunit时出现此错误

错误:调用未定义的方法测试\ Feature\ViewConcertListingTest :: see()

这是我的代码:

class ViewConcertListingTest扩展TestCase {使用DatabaseMigrations;

/** @test */
public function user_can_view_a_concert_listing()
{
    // Arrange
    // Create a concert
    $concert = Concert::create([
        'title' => 'The Red Chord',
        'subtitle' => 'with Animosity and Lethargy',
        'date' => Carbon::parse('December 13, 2016 8:00pm'),
        'ticket_price' => 3250,
        'venue' => 'The Mosh Pit',
        'venue_address' => '123 Example Lane',
        'city' => 'Laraville',
        'state' => 'ON',
        'zip' => '17916',
        'additional_information' => 'For tickets, call (555) 555-5555'
    ]);

    // Act
    // View the concert listing
    $this->get('/concerts/' . $concert->id);

    // Assert
    // See the concert details
    $this->see('The Red Chord');
    $this->see('with Animosity and Lethargy');
    $this->see('December 13, 2016');
    $this->see('8:00pm');
    $this->see('32.50');
    $this->see('The Mosh Pit');
    $this->see('123 Example Lane');
    $this->see('Laraville, ON 17916');
    $this->see('For tickets, call (555) 555-5555');
}

}

有帮助吗？谢谢!

如果其他人遇到了这个错误并且问题的代码看起来很熟悉,那么这来自Adam Wathan的测试驱动的Laravel课程(强烈推荐!).

如果您在本课程的早期课程中学习但使用的是Laravel 5.5,则需要更新以下内容:

1. 而不是$this->get('...');,使用$response = $this->get('...');.
2. 而不是$this->see(),使用$response->assertSee().

Laravel已经将5.3测试层和帮助器方法从5.3(在屏幕录像中使用的Laravel版本)更新到5.5.您的5.5功能规范应更新为以下内容:

<?php

class ViewConcertListingTest extends TestCase
{

    use DatabaseMigrations;

    /** @test */
    public function user_can_view_a_concert_listing()
    {
        // Arrange
        // Create a concert
        $concert = Concert::create([
            'title' => 'The Red Chord',
            // ...
        ]);

        // Act
        // View the concert listing
        $response = $this->get('/concerts/' . $concert->id);

        // Assert
        // See the concert details
        $response->assertSee('The Red Chord');
        // ...
    }
}
