laravel -无法运行phpunit - TestCase：：setUp()必须与PHPUnit兼容

我尝试运行phpunit，得到这个错误：

PHP Fatal error:  Declaration of Illuminate\Foundation\Testing\TestCase::setUp() must be compatible with PHPUnit\Framework\TestCase::setUp(): void in /Users/xxx/dev/xxx/vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestCase.php on line 65

所以我找到了解决方案：将:void添加到测试的setUp()和tearDown方法中。
所以我修改了laravel里面的文件：vendor/laravel/framework/src/Illuminate/Foundation/Testing/TestCase.php

public function setUp():void
{
  parent::setUp();
}

public function tearDown():void
{
  parent::tearDown();
}

它工作，但问题是，我正在修改一个文件，这是在vendor目录，它可能会被覆盖的 composer 命令。
如何在不修改vendor目录中的文件的情况下应用此解决方案？
我的composer.json文件

你使用的是PHPUnit 8，它与Laravel 5.6不兼容，你必须使用PHPUnit 7，而不是8+。为什么？

PHPUnit TestCase.php

/**
 * This method is called before each test.
 */
protected function setUp(): void
{
}

正如你所看到的，它定义了: void，但是Laravel 5.6没有：

/**
 * Setup the test environment.
 *
 * @return void
 */
protected function setUp()
{

因为这些文件是vendor文件，你不能编辑它们，但要安装每个文件的正确版本。你的修复方法是将你的composer.json从"phpunit/phpunit": "*"更改为"phpunit/phpunit": "^7.0"，就像官方的Laravel 5.6 composer.json一样：https://github.com/laravel/laravel/blob/0d5c1c81ff6faafbd8cc995aa3d0cd1b155df4c3/composer.json#L18。
您可以在这里看到，PHPUnit 7与Laravel 5.6 TestCase.php文件相比具有有效的定义：

/**
 * This method is called before each test.
 */
protected function setUp()/* The :void return type declaration that should be here would cause a BC issue */
{
}

/**
 * This method is called after each test.
 */
protected function tearDown()/* The :void return type declaration that should be here would cause a BC issue */
{
}
