How to unit test GraphQL responses on Lumen? - json

Question

I'm trying to test an API I built with Lumen (PHP), but I'm stuck on unit test my GraphQL responses`.
This is what I have tried:
class MovieQueryTest extends Tests\GraphQLTestCase
{
use DatabaseMigrations;
public function testCanSearch()
{
Movie::create([
'name' => 'Fast & Furious 8',
'alias' => 'Fast and Furious 8',
'year' => 2016
]);
$response = $this->post('/graphql/v1', [
'query' => '{movies(search: "Fast & Furious"){data{name}}}'
]);
$response->seeJson([
'data' => [
'movies' => [
'data' => [
'name' => 'Fast & Furious 8'
]
]
]
]);
}
}
This is what I got:
PHPUnit 7.5.6 by Sebastian Bergmann and contributors.
F..... 6
/ 6 (100%)
Time: 690 ms, Memory: 24.00 MB
There was 1 failure:
1) MovieQueryTest::testCanSearch Unable to find JSON fragment
["data":{"movies":{"data":{"name":"Fast & Furious"}}}] within
[{"data":{"movies":{"data":[]}}}]. Failed asserting that false is
true.
The problem is that my data structure doesn't match the JSON's structure. While my data is inside an Array, the JSON's data is inside an Object and I can't figure out how to make it match:
["data":{"movies":{"data":{"name":"Fast & Furious 8"}}}]
[{"data":{"movies":{"data":[{"name":"Fast & Furious 8"}]}}}]
How can I make my data structure match the JSON's data structure or there is a better way to unit test GraphQL responses on Lumen?

Answer 1

You need to wrap 'name' => 'Fast & Furious 8' inside it's own array, for example:
The following:
$array = [
'data' => [
'movies' => [
'data' => [
['name' => 'Fast & Furious 8']
]
]
]
];
Should output:
{"data":{"movies":{"data":[{"name":"Fast & Furious 8"}]}}}
