扩展抽象测试类时找不到测试类答案

【问题标题】：Test class not found when extending abstract test class扩展抽象测试类时找不到测试类

【问题描述】：

我目前正在使用 lumen 框架 (v5.6) 并为我的代码编写单元测试。

我有一个基类TestCase:

namespace Tests;

$_SERVER["http_proxy"] = "";

abstract class TestCase extends \Laravel\Lumen\Testing\TestCase
{
    /**
     * Creates the application.
     *
     * @return \Laravel\Lumen\Application
     */
    public function createApplication()
    {
        return require __DIR__.'/../bootstrap/app.php';
    }
}

我使用这个基类来编写我的测试，但是我有两个测试有很多重叠（它们都测试接口的实现），所以我把通用逻辑放在一个抽象类中：

namespace Tests\App\IO;

use App\io\PageDataParser;
use App\Models\AdvancedArray;
use App\Services\PageService;
use Mockery;
use Tests\TestCase;

abstract class ParsePageDataTestCase extends TestCase
{

    // Test logic here, but not relevant for the question

}

最后我在实际测试中使用了这个抽象类：

namespace Tests\App\IO;

use App\io\JsonPageDataParser;
use App\Models\AdvancedArray;

class JsonParsePageDataTestCaseTest extends ParsePageDataTestCase
{

   // Test are here, but not relevant for the question
}

但是，当我执行 JsonParsePageDataTestCaseTest 时，我收到以下错误：

PHP 致命错误：在第 15 行的 \tests\app\io\JsonParsePageDataTest.php 中找不到类“Tests\ParsePageDataTestCase”

我已验证文件夹的结构已更正，也尝试使用'composer dump-autoloadand verified that mycomposer.jsonhas an entry which specifies a classmap to 'tests/。

我使用加载bootstrap/app.php 的phpunit.xml 执行我的测试，但我仍然收到此错误。

phpunit.xml:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="bootstrap/app.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false">
    <testsuites>
        <testsuite name="Application test Suite">
            <directory suffix="Test.php">./tests</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./app</directory>
        </whitelist>
    </filter>
    <php>
           <!-- ENV variables go here -->

    </php>
</phpunit>

最后是我的composer.json：

    "name": "laravel/lumen",
    "description": "The Laravel Lumen Framework.",
    "keywords": ["framework", "laravel", "lumen"],
    "license": "MIT",

    },
    "autoload": {

            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/"
        ]
    },
    "scripts": {
        "post-root-package-install": [
            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ]
    },
    "config": {
        "preferred-install": "dist",
        "sort-packages": true,
        "optimize-autoloader": true
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

如果您需要更多信息，请告诉我。

提前谢谢你！

【问题讨论】：

在 JsonParsePageDataTestCaseTest.php 上的命名空间声明后缺少 ParsePageDataTestCase 使用语句。
@GabrielPereira，感谢您的回复。但它们位于同一个命名空间中，因此不需要使用语句
你能分享你的 composer.json 自动加载吗？
@GabrielPereira 是的，我更新了问题
您是否尝试过加载您的测试类，将它们放在 psr-4 上自动加载为 "Test\\": "tests/" ？

标签： php laravel unit-testing phpunit lumen

【解决方案1】：

这是 Lumen 安装的问题。当您安装 laravel 时，测试文件夹在 autoload-dev 上配置为 psr-4：

{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
...
"autoload-dev": {
    "psr-4": {
        "Tests\\": "tests/"
    }
},
...
"minimum-stability": "dev",
"prefer-stable": true

}

但在 Lumen 上安装并不像我们在下面看到的那样：

{
"name": "laravel/lumen",
"description": "The Laravel Lumen Framework.",
"keywords": ["framework", "laravel", "lumen"],
"license": "MIT",
"type": "project",
"require": {
    "php": ">=7.1.3",
    "laravel/lumen-framework": "5.7.*",
    "vlucas/phpdotenv": "~2.2"
},
"require-dev": {
    "fzaninotto/faker": "~1.4",
    "phpunit/phpunit": "~7.0",
    "mockery/mockery": "~1.0"
},
"autoload": {
    "classmap": [
        "database/seeds",
        "database/factories"
    ],
    "psr-4": {
        "App\\": "app/"
    }
},
"autoload-dev": {
    "classmap": [
        "tests/"
    ]
},
"scripts": {
    "post-root-package-install": [
        "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
    ]
},
"config": {
    "preferred-install": "dist",
    "sort-packages": true,
    "optimize-autoloader": true
},
"minimum-stability": "dev",
"prefer-stable": true
}

因此，为了使其正常工作，您需要将自动加载更改为：

"autoload-dev": {
    "classmap": [
        "tests/"
    ],
    "psr-4": {
        "Tests\\": "tests/"
    }
}
