Test a REST get request - rest

Question

How do I test a GET request of a REST API with PHPUnit 4.1? I use the Slim PHP-Framework and could manage to test the response code but not the body or header.
This is what I have so far:
TestClass:
class AssetTest extends PHPUnit_Framework_TestCase
{
public function request($method, $path, $options = array())
{
// Capture STDOUT
ob_start();
// Prepare a mock environment
Environment::mock(array_merge(array(
'REQUEST_METHOD' => $method,
'PATH_INFO' => $path,
'SERVER_NAME' => 'slim-test.dev',
), $options));
$app = new \Slim\Slim();
$this->app = $app;
$this->request = $app->request();
$this->response = $app->response();
// Return STDOUT
return ob_get_clean();
}
public function get($path, $options = array()){
$this->request('GET', $path, $options);
}
public function testGetAssets(){
$this->get('/asset');
$this->assertEquals('200', $this->response->status());
}
}
If my JSON response of http://example.com/asset looks like this (Code 200):
[
{
"AssetID": "4b0be88b9e853",
"AssetStatusID": "1"
}
]

Everything is good. To get the body of response just call the
$response->getBody() and use json_decode to decode this response. To get the header call the $response->getHeaders().
In your case it will by $this->response->getBody(). So your test
method will be look like this
public function testGetAssets(){
$this->get('/asset');
$response = json_decode($this->response->getBody(), true); //response body
$headers = $this->response->getHeaders() //response headers
$this->assertEquals('200', $this->response->status());
}
