ZF2 - How to pass config array to base test case class - zend-framework2

Question

When using AbstractControllerTestCase (or it's subclasses) you get a convenient method setApplicationConfig() that let's you pass an array similar to config/application.config.php, so that you include only the modules you need in order to test.
How do you pass the array that goes into config/autoload/global.php to AbstractControllerTestCase?
PS: if it helps, I'm trying to pass a custom ORM connection that uses SQLite

Answer 1

You can simply make separate config files to be used when testing and load those inside your test controller.
for example;
copy config/application.config.php to config/application.config.test.php
Make a small change to allow us to load separate test config files without touching the global config files used by the production application.
'config_glob_paths' => array(realpath(__DIR__) . '/autoload/{,*.}{global,test}.php'),
This will allow us to override any config values we need as the test config files are loaded after the usual global config files. We can now please any test specific configureation inside test.php, anything.test.php etc.
now you can copy
autoload/global.php to autoload/test.php
You can now change config items and these will override those inside global.php
autoload/test.php
<?php
return array(
'db' => array(
'driver' => 'Pdo',
'dsn' => 'sqlite:' . __DIR__ .'/../../data/testing.sqlite',
//'dsn' => 'mysql:dbname=somedatabase;host=localhost',
'username' => 'dbuser',
'password' => 'passwordgoeshere',
),
You could also change the driver to use SQL lite or what ever your require to run your tests.
Now you just need to make your test controllers load our new application config file:
use Zend\Test\PHPUnit\Controller\AbstractHttpControllerTestCase;
class ExampleTest extends AbstractHttpControllerTestCase
{
public function setUp()
{
$this->setApplicationConfig(
include __DIR__ . '/../../config/application.config.test.php'
);
}
This allows you to keep all your test configuration separate to your main application config settings.
