编写 Lighthouse 5 的自动化测试用例，要在查询中使用变量时，报错：Syntax Error: Expected Name, found $，进而 Failed asserting that an array has the subset Array
1、参考网址：https://lighthouse-php.com/4/testing/phpunit.html#setup ，使用 PHPUnit 进行测试。在 Lighthouse 中，通过 PHPUnit 添加自动化测试是很容易的。
2、运行 GraphQL Query API，响应 200。主要测试字段：themeAssets 的响应。如图1

3、编辑 /Modules/ThemeStore/Tests/Functional/GraphQl/OnlineStoreThemeGraphQlApiTest.php ，代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 | <?phpnamespace 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' ], ], ]); } protected function setUp(): void { parent::setUp(); $this->bootClearsSchemaCache(); }} |
4、执行命令：./vendor/bin/phpunit .\Modules\ThemeStore\Tests\Functional\GraphQl\OnlineStoreThemeGraphQlApiTest.php 。报错：Failed asserting that an array has the subset Array 。如图2

5、根源在于 响应 与 手动发送请求的响应不一致所导致。决定先编写一个不带参数的测试用例。/tests/Feature/PostsGraphQlApiTest.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 | <?phpnamespace Tests\Feature;use Nuwave\Lighthouse\Testing\MakesGraphQLRequests;use Illuminate\Foundation\Testing\TestCase as BaseTestCase;use Nuwave\Lighthouse\Testing\ClearsSchemaCache;use Tests\CreatesApplication;use App\Models\Post;class PostsGraphQlApiTest extends BaseTestCase{ use CreatesApplication, ClearsSchemaCache, MakesGraphQLRequests; public function testQueriesPosts(): void { $post = Post::factory()->create(); $response = $this->graphQL(' { posts { id title content } } '); $response->assertJson([ 'data' => [ 'posts' => [ [ 'id' => $post->id, 'title' => $post->title, 'content' => $post->content, ] ], ], ]); } protected function setUp(): void { parent::setUp(); $this->bootClearsSchemaCache(); }} |
6、运行测试：./vendor/bin/phpunit .\tests\Feature\PostsGraphQlApiTest.php ，报错：Failed asserting that an array has the subset Array。但是响应确定是 JSON 的结构的，只不过未匹配上第一个元素。如图3

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 | { "id": "104", "title": "Tenetur id labore dolores aperiam.",it vel ut corrupti repellat quaerat.

7、获取 $posts 数组的最后一个键值，然后匹配成功。运行测试通过。如图4

9、最后发现根源在于花括号多了一层。如图5
