unit-testing - phpunit laravel 5.4 错误

Question

我需要在 laravel 中使用单元测试，但他们需要下载库 laravel/browser-kit-testing当我下载它时告诉我他们需要 php 5.6我使用的是 php 5.4。

 public function testBasicTest()
    {
        $this->visit('/home')
            ->seePageIs('/login');
        $response = $this->call('GET', '/dradmin');
        $this->assertEquals(200, $response->status());
        $this->visit('/login')
            ->type('mahmoud@mahmoud.com', 'email')
            ->type('123456', 'password')
            ->press('Login')
            ->seePageIs('/home');

    }
}

当使用phpunit

Error: Call to undefined method Tests\Feature\UserTest::visit()

/Users/mahmoud310/ecare/tests/Feature/UserTest.php:21

我阅读了其他问题 Laravel 5.4 HTTP testing - method seeInElement

使用命令laravel/browser-kit-testing可以解决问题

在我的情况下不起作用

Answer 1

在终端中输入

composer require laravel/browser-kit-testing --dev

然后在你的项目中使用下载的文件

use Tests\CreatesApplication;
use Laravel\BrowserKitTesting\TestCase as BaseTestCase;

并且不要忘记从 BaseTestCase 进行扩展。

示例代码

<?php

namespace Tests\Feature;

use Tests\CreatesApplication;
use Tests\TestCase;
use App\User;
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;
use Laravel\BrowserKitTesting\TestCase as BaseTestCase;

class UserTest extends BaseTestCase
{
    use CreatesApplication;
    public $baseUrl = 'http://localhost';
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testExample()
    {


        $this->visit('/home')
            ->seePageIs('/login');
        

    }
}
