When writing the automated test case of Lighthouse 5, when you want to use a variable in the query, the error is reported: syntax error: expected $, and then failed Asserting that an array has the subset array
1. Reference URL:https://lighthouse-php.com/4/testing/phpunit.html#setup, test with phpunit . In Lighthouse, it is easy to add automated tests with phpunit.
2. Run the GraphQL Query API and respond 200. The main test field: The responses of TheMeAssets. as shown in Figure 1
Figure 1
3. Edit /modules/themestore/tests/functional/graphql/onlineStoreEthemeGraphQLapTest.php, the code is as follows
graphQL('
{
query GetThemeById($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. Execute the command: ./vendor/bin/phpunit .\modules\themestore\tests\functional\graphql\OnlineStoreEthemeGraphQLapTest.php . Error: Failed asserting that an array has the subset array . as shown in Figure 2

5. The root cause is that the response is inconsistent with the response to manually sending the request. Decided to write a test case without parameters. /tests/feature/PostsGraphQLapTest.php
create();
