1、编写 Lighthouse 5 的自动化测试用例时，将一个测试方法拆分为二个测试方法。现阶段是一个方法



    public function testGetThemeById(): void
    {
        $response = $this->graphQL('
            query GetThemeById($id: ID!) {
                onlineStoreTheme(themeId: $id) {
                    id
                    editable
                    createdAt
                    name
                    themeAssets {
                        id
                        themeId
                        version
                        key
                        mimeType
                        category
                        schema
                        createdAt
                        updatedAt
                    }
                }
            }
            ',
            [
                'id' => 'vogue',
            ]
        );

        $response->assertJson(
            [
                'data' => [
                    'onlineStoreTheme' => [
                        'id' => 'vogue'
                    ],
                ],
            ]
        )->assertJsonStructure([
                'data' => [
                    'onlineStoreTheme' => [
                        'themeAssets' => [
                            [
                                'id',
                                'themeId',
                                'version',
                                'key',
                                'mimeType',
                                'category',
                                'schema',
                                'createdAt',
                                'updatedAt',
                            ]
                        ]
                    ]
                ],
            ]
        );
    }

2、拆分为二个方法

            [
                'id' => 'vogue',
            ]
        );

        $response->assertJsonStructure(
            [
                'data' => [
                    'onlineStoreTheme' => [
                        'themeAssets' => [
                            [

                                'key',
                                'mimeType',

                ],

        );
    }

    protected function setUp(): void
    {
        parent::setUp();

        $this->bootClearsSchemaCache();
    }
}




</pre>

3、运行测试，报错：Error: Call to undefined method Illuminate\Support\Facades\Config::set()。如图1

4、此时，如果删除掉方法中的其中任意一个方法，皆可以测试通过。

<pre class="wp-block-syntaxhighlighter-code">

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="vendor/autoload.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="true"
         stopOnFailure="false">
</phpunit>


</pre>

5、分别在二个方法的第一行打印 $this->app[‘config’] ，确认仅有第一个方法打印成功，第二个方法报错：Error: Call to undefined method Illuminate\Support\Facades\Config::set()。可以确认在第二个方法中，应用实例已经不复存在了的。 6、参考网址：https://phpunit.readthedocs.io/en/9.5/configuration.html 。processIsolation 属性。This attribute configures whether each test should be run in a separate PHP process for increased isolation。可能的值：true 或 false(默认值：false)。此属性配置每个测试是否应在单独的 PHP 进程中运行以增加隔离。 7、编辑文件 /phpunit.xml，设置 processIsolation=”true”。如图2

编辑文件 /phpunit.xml，设置 processIsolation="true" — 图2

8、再次运行测试，测试通过。如图3

9、如果不设置 processIsolation=”true” 的话，可以在运行测试时添加选项 –process-isolation。仍然可以测试通过。如图4



PS E:\wwwroot\object> ./vendor/bin/phpunit --process-isolation .\Modules\ThemeStore\Tests\Functional\GraphQl\OnlineStoreThemeGraphQlApiTest.php
