Class 'sample\question2\Hello' 未找到 composer 和 phpunit

Question

我使用 composer 和 phpunit 但出现错误 "Class not found"。

目录结构：

php_sample/sample/question/
php_sample/sample/question/Hello.php
php_sample/sample/question/测试/HelloTest.php

并创建了composer.json

{
    "require-dev": {
    "phpunit/phpunit": "4.5.*"
    }
}

我是这样安装composer的

$ curl -sS https://getcomposer.org/installer | php
$ ./composer.phar update
$ ./composer.phar install --dev

Hello.php是这样的

<?php
namespace sample\question;

class Hello
{
    public function hello()
    {
        return 'Hello, world';
    }
}

?>

test/HelloTest.php是这样的.

<?php
namespace sample\question\tests;

use sample\question\Hello;

class HelloTest extends \PHPUnit_Framework_TestCase
{
    /**
     * @var Hello
     */
    public $SUT;

    /**
     * @test
     */
    public function canPrint()
    {
        $this->assertThat($this->SUT->hello(), $this->equalTo('Hello, world'));
    }

    protected function setUp()
    {
        $this->SUT = new Hello;
    }
}

然后，我运行这个脚本发生了错误。

$ vendor/bin/phpunit --bootstrap vendor/autoload.php tests/HelloTest.php


PHP Fatal error:  Class 'sample\question\Hello' not found in /Users/foobar/work/php_sample/sample/question/tests/HelloTest.php on line 32

如果你能回答我就太好了

您正确地使用 --bootstrap vendor/autoload.php 引导 PHPUnit 以通过 Composer 生成的自动加载器自动加载文件，但是

您的 composer.json 文件缺少 autoload 和 autoload-dev 部分。

{
    "require-dev": {
        "phpunit/phpunit": "4.5.*"
    }
    "autoload": {
         "psr-4": {"sample\question\": "php_sample/sample/question/"}
    }
    "autoload-dev": {
         "psr-4": {"sample\question\tests\": "php_sample/sample/question/tests/"}
    }
}

然后 re-dump/re-generate Composer Autoloader 和 composer dump-autoload。

旁注：我不确定文件夹结构是否真的有效..

也许值得将您的项目文件夹布局更改为：

project/src
project/tests

project/src/sample/question/
project/tests/sample/question/

然后变成

"autoload": {
    "psr-4": {"sample\question\": "src/"}
}
"autoload-dev": {
    "psr-4": {"sample\question\tests\": "tests/"}
}
