Php Mockery - How To Mock Correctly - php

Question

I am trying to add some existing test cases to a pre existing project
Here is the API class
<?php
namespace MyApp\Api;
use MyApp\ApiBase;
use MyApp\Ethereum as Eth;
use PHPUnit\Runner\Exception;
/**
* Class Ethereum
* #package MyApp\Api
*/
class Ethereum extends ApiBase {
/**
* Function to get balances
* #param array $addresses
* #param string $tag
* #return array
*/
public function getBalances(array $addresses, string $tag = 'latest') {
$data = [];
foreach ($addresses as $addr) {
// validate address
if (!Eth::validateAddress($addr)) {
continue;
}
}
return $data;
}
}
The service class
<?php
namespace MyApp;
use MyApp\Ethereum\GethIpc;
use MyApp\Ethereum\GethWebsocket;
use PHPUnit\Runner\Exception;
/**
* Class Ethereum
* #package MyApp
*/
class Ethereum {
public static $subscriptions = [];
/**
* Ethereum constructor.
*/
public function __construct() {
$this->connection = new GethWebsocket();
$connect = $this->connection->connect();
}
/**
* Function to validate an address
* #param string $address
* #return bool
*/
public static function validateAddress(string $address) {
return preg_match("/^(0x)?[0-9a-fA-F]{40}$/", $address) !== 0;
}
}
My test class
<?php
declare(strict_types=1);
namespace MyApp\Test;
use MyApp\Api\Ethereum;
use MyApp\Ethereum as Eth;
use PHPUnit\Framework\TestCase;
use PHPUnit\Runner\Exception;
use Mockery;
use Mockery\Adapter\Phpunit\MockeryTestCase;
/**
* #covers MyApp\Api\Ethereum
*/
final class EthereumTest extends MockeryTestCase {
protected $ethereumApi;
protected $ethereum_address;
//Setup method called before every method
protected function setUp(): void {
$this->ethereumApi = new Ethereum();
$this->ethereum_address = '0x0000000000000000000000000000000' . rand(100000000, 999999999);
//Mockery::globalHelpers();
//$mock = mock(MyApp\Ethereum::class);
}
public function testGetBalances_ValidEthereumAddress(): void {
$mockEthereumService = Mockery::mock("Eth");
$mockEthereumService->shouldReceive('validateAddress')->once()->with($this->ethereum_address)->andReturn(true);
//$mockEthereumService->shouldReceive('msg')->once()->with($this->ethereum_address)->andReturn(true);
$addresses = [$this->ethereum_address];
$result = $this->ethereumApi->getBalances($addresses);
$this->assertNotEmpty($result);
}
public function tearDown()
{
Mockery::close();
}
}
Everytime I run the test class - the mock is not working and the actual service class method is being called
Can anyone offer assistance on how I should get this mock example working correctly?

Not having experience with Mockery myself, but after looking into the documentation
http://docs.mockery.io/en/latest/reference/creating_test_doubles.html#overloading
http://docs.mockery.io/en/latest/cookbook/mocking_hard_dependencies.html
I'd assume you need to use the "overload" prefix and the full classname and remove the use-statement for MyApp\Ethereum from your test case.
