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
图1
3、编辑 /Modules/ThemeStore/Tests/Functional/GraphQl/OnlineStoreThemeGraphQlApiTest.php ，代码如下
<?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'
],
],
]);
}
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
<?php
namespace 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

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

use Illuminate/Foundation/Testing/TestCase as BaseTestCase;
use Nuwave/Lighthouse/Testing/ClearsSchemaCache;

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
}
}
');
$responsePosts = $response->json("data.posts");
$lastKey = array_key_last($responsePosts);
$response->assertJson([
'data' => [
'posts' => [
$lastKey => [
'id' => $post->id,
'title' => $post->title,
'content' => $post->content,
]
],
],
]);
}
protected function setUp(): void
{
parent::setUp();
$this->bootClearsSchemaCache();
}
}

9、最后发现根源在于花括号多了一层。如图5
图5
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'
],
],
]);
}
10、运行测试，测试通过。如图6
