简单 PHP 单元测试的自动加载文件不起作用

Question

我正在尝试熟悉 PHPUnit，我遵循了所有说明 here("Getting Started with PHPUnit 7")。

我copy/pasted那些src/Email.php和tests/EmailTest.php代码源。我的问题是当我尝试运行 ./phpunit --bootstrap src/autoload.php tests/EmailTest 时。文档说我必须创建那个 src/autoload.php，所以我按照提到的第一个例子 here("Autoloading Classes"):

<?php
// Maybe I do not need this require_once() stuff?
require_once('src/Email.php');
require_once('tests/EmailTest.php');

spl_autoload_register(function ($class_name) {
    include $class_name . '.php';
});

$obj  = new Email('bart.simpson@outlook.com');
$obj2 = new EmailTest(); 
?>

但是当我使用之前的命令进行测试时收到此错误消息：

PHP Error:  Call to private Email::__construct() from context 'PHPUnit\Util\FileLoader' in /var/www/html/php_project/src/autoload.php on line 9
PHP Stack trace:

#7 {main}

我很久以前就用过这样的东西，如果你能帮我刷新一下...

P.S。鉴于我的设置，我宁愿运行 ./vendor/bin/phpunit --bootstrap src/autoload.php tests/EmailTest 但这与我目前所写的内容没有区别。

编辑：

根据以下评论，我再次对构造函数 public 和运行进行了测试，我收到了此错误消息：

如果您使用 Composer 安装 PHPUnit，我认为最好也使用它来自动加载，而不是自己去打扰它。

请允许我分享我对 PHP 个项目的（自以为是的）设置：

类在 ./src/
./tests/

composer.json（在更大的项目中选中 PSR-4 而不是 classmap）：

"autoload": {
    "classmap": [
        "src/"
    ]
},
"autoload-dev": {
    "classmap": [
        "tests/"
    ]
},

phpunit.xml（用于保存设置，因此您不必一直在 CLI 中传递它）：

<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="vendor/autoload.php">
    <testsuites>
        <testsuite name="Tests">
            <directory suffix="Test.php">./tests</directory>
        </testsuite>
    </testsuites>
</phpunit>

然后我可以不带选项地调用 ./vendor/bin/phpunit，它会运行我所有的测试。

Using classmap it may be necessary to run composer dump to regenerate autoload files after adding new classes/files.
