1. When writing automated test cases for Lighthouse 5, I split one test method into two. At this stage, it is a single method.
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. Split into two methods.
<?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. Run the test, and an error is reported: Error: Call to undefined method Illuminate\Support\Facades\Config::set(). As shown in Figure 1.

4. At this point, if I remove either of the two methods, the test passes.

<phpunit backupGlobals="false"

5. I printed $this->app[‘config’] on the first line of both methods respectively. I confirmed that only the first method prints successfully, while the second method throws an error: Error: Call to undefined method Illuminate\Support\Facades\Config::set(). This confirms that in the second method, the application instance no longer exists.
6. Reference URL: https://phpunit.readthedocs.io/en/9.5/configuration.html . The processIsolation attribute. This attribute configures whether each test should be run in a separate PHP process for increased isolation. Possible values: true or false (default: false). This attribute configures whether each test should be run in a separate PHP process for increased isolation.
7. Edit the file /phpunit.xml and set processIsolation=”true”. As shown in Figure 2.
8. Run the test again, and it passes. As shown in Figure 3.
9. If processIsolation=”true” is not set, you can add the –process-isolation option when running the test. The test will still pass. As shown in Figure 4.
