php - GuzzlePHP mock response content -

i want mock response guzzle request:

 $response = new response(200, ['x-foo' => 'bar']);   //how set content of $response to--> "some mocked content"   $client = mockery::mock('guzzlehttp\client');  $client->shouldreceive('get')->once()->andreturn($response); 

i noticed need add third parameter interface:

 guzzlehttp\stream\streaminterface 

but there many implementations of it, , want return simple string. ideas?

edit: use this:

 $response = new response(200, [], guzzlehttp\stream\stream::factory('bad xml here')); 

but when check this:

$response->getbody()->getcontents() 

i empty string. why this?

edit 2: happened me when used xdebug, when runs works great!

the previous answer guzzle 3. guzzle 5 uses following:

<?php $body = guzzlehttp\stream\stream::factory('some mocked content'); $response = new response(200, ['x-foo' => 'bar'], $body);
