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
<?php
namespace Modules\ThemeStore\Tests\Functional\GraphQl;
use Nuwave\Lighthouse\Testing\MakesGraphQLRequests;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;
use Nuwave\Lighthouse\Testing\ClearsSchemaCache;
use Tests\CreatesApplication;
class OnlineStoreThemeGraphQlApiTest extends BaseTestCase
{
use CreatesApplication,
ClearsSchemaCache,
MakesGraphQLRequests;
public function testGetThemeById(): void
{
$response = $this->graphQL('
query GetThemeById($id: ID!) {
onlineStoreTheme(themeId: $id) {
id
editable
createdAt
name
}
}
',
[
'id' => 'vogue',
]
);
$response->assertJson(
[
'data' => [
'onlineStoreTheme' => [
'id' => 'vogue'
],
],
]
);
}
public function testGetThemeAssetsById(): void
{
$response = $this->graphQL('
query GetThemeAssetsById($id: ID!) {
onlineStoreTheme(themeId: $id) {
themeAssets {
id
themeId
version
key
mimeType
category
schema
createdAt
updatedAt
}
}
}
',
[
'id' => 'vogue',
]
);
$response->assertJsonStructure(
[
'data' => [
'onlineStoreTheme' => [
'themeAssets' => [
[
'id',
'themeId',
'version',
'key',
'mimeType',
'category',
'schema',
'createdAt',
'updatedAt',
]
]
]
],
]
);
}
protected function setUp(): void
{
parent::setUp();
$this->bootClearsSchemaCache();
}
}
3、运行测试，报错：Error: Call to undefined method Illuminate\Support\Facades\Config::set()。如图1
PS E:\wwwroot\object> ./vendor/bin/phpunit .\Modules\ThemeStore\Tests\Functional\GraphQl\OnlineStoreThemeGraphQlApiTest.php PHPUnit 7.5.20 by Sebastian Bergmann and contributors. .E 2 / 2 (100%) Time: 1.02 seconds, Memory: 70.00 MB There was 1 error: 1) Modules\ThemeStore\Tests\Functional\GraphQl\OnlineStoreThemeGraphQlApiTest::testGetThemeAssetsById Error: Call to undefined method Illuminate\Support\Facades\Config::set() E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Support\ServiceProvider.php:63 E:\wwwroot\object\Modules\ThemeSetting\Providers\ThemeServiceProvider.php:103 E:\wwwroot\object\Modules\ThemeSetting\Providers\ThemeServiceProvider.php:37 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:616 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\ProviderRepository.php:75 E:\wwwroot\object\vendor\nwidart\laravel-modules\src\Laravel\Module.php:33 E:\wwwroot\object\vendor\nwidart\laravel-modules\src\Module.php:264 E:\wwwroot\object\vendor\nwidart\laravel-modules\src\FileRepository.php:321 E:\wwwroot\object\vendor\nwidart\laravel-modules\src\Providers\BootstrapServiceProvider.php:23 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:616 E:\wwwroot\object\vendor\nwidart\laravel-modules\src\ModulesServiceProvider.php:31 E:\wwwroot\object\vendor\nwidart\laravel-modules\src\LaravelModulesServiceProvider.php:17 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Container\BoundMethod.php:36 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Container\Util.php:37 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Container\BoundMethod.php:93 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Container\BoundMethod.php:37 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Container\Container.php:590 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:856 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:839 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:840 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Bootstrap\BootProviders.php:17 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Application.php:219 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Console\Kernel.php:320 E:\wwwroot\object\tests\CreatesApplication.php:18 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Testing\TestCase.php:102 E:\wwwroot\object\vendor\laravel\framework\src\Illuminate\Foundation\Testing\TestCase.php:81 E:\wwwroot\object\Modules\ThemeStore\Tests\Functional\GraphQl\OnlineStoreThemeGraphQlApiTest.php:74 phpvfscomposer://E:\wwwroot\object\vendor\phpunit\phpunit\phpunit:60 ERRORS! Tests: 2, Assertions: 1, Errors: 1. PS E:\wwwroot\object>
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。
<?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>
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
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 PHPUnit 7.5.20 by Sebastian Bergmann and contributors. .. 2 / 2 (100%) Time: 2.56 seconds, Memory: 16.00 MB OK (2 tests, 14 assertions) PS E:\wwwroot\object>
