Symfony web test case JSON

After you do $client->request(...) call, you can do $client->getResponse() to get server response.

You can then assert status code and check it's contents, for example:

$client->request('GET', '/my-url');$response = $client->getResponse();$this->assertSame(200, $response->getStatusCode());$responseData = json_decode($response->getContent(), true);// etc...

There is a PHPUnit\Framework\Assert::assertJson() method since this commit You can also test 'Content-Type' of response.

$response = $client->getResponse();$this->assertTrue($response->headers->contains('Content-Type', 'application/json'));$this->assertJson($response->getContent());$responseData = json_decode($response->getContent(), true);

The willdurand/rest-extra-bundle bundle provides additional helpers to test JSON. To test equality there is already a built-in assertion for this purpose:

use Bazinga\Bundle\RestExtraBundle\Test\WebTestCase as BazingaWebTestCase;// ...$client->request('GET', '/my-url');$response = $client->getResponse();$this->assertJsonResponse($response, Response::HTTP_OK);$this->assertJsonStringEqualsJsonString($expectedJson, $response);

Note that the assertJsonStringEqualsJsonString assertion will take in charge the normalization of both $expectedJson and $response strings.
