FnMock
A PHP testing tool for mocking functions., (*1)
Most mocking frameworks only allow mocking of objects. FnMock is a tiny class that makes it easy to test functions outside the context of a class., (*2)
Important: Mocking functions is only supported when the function caller is within a namespace., (*3)
Example
// Code
namespace Http;
class Client {
public function touch($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
}
```php
// Test
use FnMock\FnMock;, (*4)
$client = new Http\Client();, (*5)
FnMock::mock('Http\curl_exec', function($ch) {
$url = curl_getinfo($ch)['url'];
assert($url === 'http://google.com');
return 'Fake response from server';
});, (*6)
$response = $client->touch('http://google.com');
assert($response === 'Fake response from server');, (*7)
// Important: Reset FnMock as part of your tearDown process
FnMock::reset();, (*8)
## Install
composer require fnmock/fnmock, (*9)
## Integrate it with PHPUnit
```php
use FnMock\FnMock;
class TestCase extends \PHPUnit_Framework_TestCase
{
protected function mockFunction($fn, callable $callback)
{
FnMock::mock($fn, $callback);
}
public function tearDown()
{
FnMock::reset();
parent::tearDown();
}
}
Or just use the trait we provide, (*10)
use FnMock\PHPUnitTrait;
class TestCase extends \PHPUnit_Framework_TestCase
{
use PHPUnitTrait;
}
