Charge up your app or SDK with a testing library specifically for Symfony/HttpClient. Hybrid covers the process of setting up a mock handler, recording history of requests, and provides several convenience methods for creating expectations and assertions on that history.


composer require --dev --prefer-dist blastcloud/hybrid

Example Usage


use BlastCloud\Hybrid\{Expectation, UsesHybrid};
use Symfony\Component\HttpClient\Response\MockResponse;
use PHPUnit\Framework\TestCase;

class SomeTest extends TestCase
    use UsesHybrid;

    public $classToTest;

    public function setUp(): void
        $client = $this->hybrid->getClient([
            /* Any configs for a client */
            "base_uri" => "https://example.com/api"
        // You can then inject this client object into your code or IOC container.
        $this->classToTest = new ClassToTest($client);

    public function testSomethingWithExpectations()
            ->withHeader("X-Authorization", "some-key")
            ->willRespond(new MockResponse("Some body"));

    public function testSomethingWithAssertions()
            new MockResponse(null, ['http_code' => 204]),
            new \Exception("Some message"),
            // any needed responses to return from the client.
        // ... Some other number of calls
        $this->hybrid->assertAll(function (Expectation $expect) {
            return $expect->withHeader("Authorization", "some-key");
