php-guzzleHow to mock requests with Guzzle in PHP?

Mocking requests with Guzzle in PHP is a great way to test your application without making actual requests.

$mock = new \GuzzleHttp\Handler\MockHandler([
    new \GuzzleHttp\Psr7\Response(200, [], '{"foo": "bar"}'),
]);

$handler = \GuzzleHttp\HandlerStack::create($mock);
$client = new \GuzzleHttp\Client(['handler' => $handler]);

$response = $client->request('GET', 'http://example.com');

echo $response->getBody();
