如何测试对象的多个属性

Question

I'm getting a JSON structure from an API and need to check, whether the successfull response has two specific attributes with specific values.

Key problems:

1. I cannot compare the whole object, as there are some properties, which may vary with each request
2. I cannot write two tests (for each attribute), because it can be considered as successful response only when both attributes matches the right values.

Example successful response:

{
    'success': true,
    'user_ip': '212.20.30.40',
    'id': '7629428643'
}

Dirty solution would be

<?php
public function testAddAccount() {
    $response = $this->api->addAccount( '7629428643' );

    $this->assertTrue(
        $response->success === TRUE &&
        $response->id === '7629428643'
    );
}

But I think there must be better and cleaner solution, is there?

Answer 1

If assertTrue() stores the boolean of a succesfull response this is the way how I would handle it. Keep in mind that this is a matter of taste.

private $lastResponse;
// $id given elsewhere
public function testAddAccount($id) {
   $this->lastResponse = $this->addAccount($id);
}

private function addAccount($id) {
   return $this->api->addAccount($id);
}

private function isLastResponseValid($response){
   return $this->lastResponse->success === TRUE 
   && $this->lastResponse->id === '7629428643';
}
