I need to make some functional tests directly in a standalone bundle. I don't want to test a controller, just some interaction between real services.
I would like to know if there is a standard/best way to do that. I did it one way but would like to know if there is a better one.
Here is my own solution (I summarize all the process for testing in a standalone bundle):
1. First, a good bundle has its own composer.json
to define its dependencies:
{
"name": "my/own-bundle",
"type": "symfony-bundle",
"description": "Symfony2 bundle that provides ...",
"keywords": ["my","own"],
"license": "MIT",
"authors": [
{
"name": "John Doe",
"email": "[email protected]"
}
],
"require": {
"php": ">=5.3.2",
"symfony/framework-bundle": ">=2.3"
},
"require-dev": {
"phpunit/phpunit": "3.7.*"
},
"autoload": {
"psr-0": { "My\\OwnBundle": "" }
},
"target-dir": "My/OwnBundle",
"minimum-stability": "dev"
}
Note the use of the dependency on symfony/framework-bundle
which is needed for our tests on services. You certainly can lower the dependencies in specifying your own real dependencies on the symfony core.
With this file I can process the command (do it) to build the vendor directory of my bundle:
$ composer update
2. Then, I set my phpunit config file:
<!-- phpunit.xml.dist -->
<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
backupStaticAttributes="false"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
processIsolation="false"
stopOnFailure="false"
syntaxCheck="false"
bootstrap="Tests/bootstrap.php"
>
<testsuites>
<testsuite name="MyOwnBundle Test Suite">
<directory>./Tests/</directory>
</testsuite>
</testsuites>
<filter>
<whitelist>
<directory>./</directory>
<exclude>
<directory>./Resources</directory>
<directory>./Tests</directory>
<directory>./vendor</directory>
</exclude>
</whitelist>
</filter>
</phpunit>
3. Then, I set the php bootstrap for the autoload of the class in my test directory:
// Tests/bootstrap.php
$file = __DIR__.'/../vendor/autoload.php';
if (!file_exists($file))
{
$file = __DIR__.'/../../../../../../vendor/autoload.php';
if (!file_exists($file))
throw new RuntimeException('Install dependencies to run test suite.');
}
$autoload = require_once $file;
These steps are standard for any test in a standalone bundle.
4. Now, I want to simulate an application to make some functionnal tests on my services:
I need a kernel class:
// Tests/AppKernel.php (you can define it in a subdirectory /Fixtures if you prefer)
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = array();
if (in_array($this->getEnvironment(), array('test'))) {
$bundles[] = new Symfony\Bundle\FrameworkBundle\FrameworkBundle();
$bundles[] = new My\OwnBundle\MyOwnBundle();
}
return $bundles;
}
public function registerContainerConfiguration(LoaderInterface $loader)
{
$loader->load(__DIR__.'/config.yml');
}
}
And the corresponding config.yml
:
# Tests/config.yml
framework:
secret: test
session:
storage_id: session.storage.mock_file
my_own:
test: 2
Here is an example with a mock for the session. Don't forget to specify the correct framework configuration nodes if you want to have access to some services (if you don't specify the node session
, you have no service session
for instance).
5. Finally, I can retrieve my services like the following in my test classes:
// Tests/Functional/Handling/Handler.php
namespace My\OwnBundle\Tests\Functional\Handling;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
class HandlerTest extends WebTestCase
{
private $handler;
protected function setUp()
{
require_once __DIR__.'/../../AppKernel.php';
$kernel = new \AppKernel('test', true);
$kernel->boot();
$container = $kernel->getContainer();
$this->handler = $container->get('my_own.handling.handler');
}
public function testHandle()
{
$this->assert($this->handler->handle());
}
}
