Question

有人用 Mockery 测试 Guzzle 吗？当我尝试为 guzzle 客户端创建模拟时，出现异常：

ErrorException: Runtime Notice: Declaration of Mockery_517a66dfe36b0::__call() should be compatible with Guzzle\Service\Client::__call($method, $args = NULL)

代码如下：

$mock = m::mock('\Guzzle\Service\Client');

谁能帮我解决这个问题？

Answer 1

如果你想创建一个 guzzle 客户端的 mock，为什么不使用 guzzle 提供的 helper：

$plugin = new Guzzle\Plugin\Mock\MockPlugin();
$plugin->addResponse(new Guzzle\Http\Message\Response(200));
$mockedClient = new Guzzle\Http\Client();
$mockedClient->addSubscriber($plugin);

// The following request will get the mock response from the plugin in FIFO order
$request = $client->get('http://www.test.com/');
$request->send();

// The MockPlugin maintains a list of requests that were mocked
$this->assertContainsOnly($request, $plugin->getReceivedRequests());

我找到了解决方法：

$mock = m::mock('stdClass');
$mock->shouldReceive('addPerson')->once()->with(m::contains(1,1))->andReturn(array('id' => 1));

$response = new \Guzzle\Http\Message\Response(409);
$exception = new \Guzzle\Http\Exception\BadResponseException('error message', 409, null);
$exception->setResponse($response);
$mock->shouldReceive('addPerson')->once()->with(m::contains(1,2))->andThrow($exception);

$response = new \Guzzle\Http\Message\Response(404);
$exception = new \Guzzle\Http\Exception\BadResponseException('error message', 404, null);
$exception->setResponse($response);
$mock->shouldReceive('addPerson')->once()->with(m::contains(1,3))->andThrow($exception);

$mapper = $this->container->get('ftb.clubs.mapper');
$mapper->setClient($mock);

$id = $mapper->addPerson(1, 1);
$this->assertEquals(
    1,
    $id
);

你觉得这有道理吗？

即使 Guzzle 自己建议，我更喜欢控制客户端，而不是依赖响应顺序。

如果我们可以模拟每个请求的响应会怎样？一对一？ 这就是我开发这个小型作曲家库的原因。

$ composer require doppiogancio/mocked-client

借助这个库，您可以使用以下方法模拟特定 url 的响应：

1. 响应对象
2. 字符串响应
3. 文件中包含的响应内容

只是一个例子

$builder = new HandlerStackBuilder();


// Add a route with a response via callback
$builder->addRoute(
    'GET', '/country/IT', static function (ServerRequestInterface $request): Response {
        return new Response(200, [], '{"id":"+39","code":"IT","name":"Italy"}');
    }
);

// Add a route with a response in a text file
$builder->addRouteWithFile('GET',  '/country/IT/json', __DIR__ . '/fixtures/country.json');

// Add a route with a response in a string
$builder->addRouteWithFile('GET',  '{"id":"+39","code":"IT","name":"Italy"}');

// Add a route mocking directly the response
$builder->addRouteWithResponse('GET', '/admin/dashboard', new Response(401));

$client = new Client(['handler' => $builder->build()]);

一旦你模拟了客户端，你可以像这样使用它：

$response = $client->request('GET', '/country/DE/json');
$body = (string) $response->getBody();
$country = json_decode($body, true);

print_r($country);

// will return
Array
(
    [id] => +49
    [code] => DE
    [name] => Germany
)
