Symfony2 using second database while testing - mysql

Question

Im using behat for testing in my symfony2 aplication. Right now I need to have two databases. First (which is working right now), for normal use, like user doing something on site. Second database (which exists and behat work on it), for tests purpose.
What I got now is two working databases, and behat. Behat use second database, but problem is that while tests flow, site doesnt use it.
My config.yml:
doctrine:
dbal:
driver: pdo_mysql
host: "%database_host%"
port: "%database_port%"
dbname: "%database_name%"
user: "%database_user%"
password: "%database_password%"
charset: UTF8
My config_test.yml:
doctrine:
dbal:
dbname: "%database_name%_test"
My 'behat.yml':
default:
suites:
default:
paths:
features: '%paths.base%/features'
bootstrap: '%paths.base%/features/bootstrap'
contexts:
- FeatureContext: ~
- EwidencjaContext:
userManager: '#fos_user.user_manager'
em: '#doctrine.orm.entity_manager'
packageManager: '#em.package_manager'
extensions:
Behat\Symfony2Extension: ~
Behat\MinkExtension:
base_url: http://my_nginx/app_test.php
goutte: ~
selenium2:
browser: "chrome"
wd_host: http://selenium_chrome:4444/wd/hub
capabilities: { "browserName": "chrome", "browser": "chrome"}
Bex\Behat\ScreenshotExtension:
image_drivers:
local:
screenshot_directory: tests/features/images/
clear_screenshot_directory: true
What can I do to change database for time tests are in progress?

Answer 1

This uses SQLite for Behat (test) environment but you can use MySQL if you want to.
config_test.yml
doctrine:
dbal:
connections:
default:
driver: pdo_sqlite
path: %kernel.cache_dir%/default.db
charset: UTF8
app_test.php
The relevant line should be: $kernel = new AppKernel('test', true);
AppKernel.php
The relevant line should be: if (in_array($this->getEnvironment(), ['dev', 'test'])) {
behat.yml
Pay attention to app_test.php.
default:
extensions:
Behat\Symfony2Extension: ~
Behat\MinkExtension:
base_url: http://your_app_domain.dev/app_test.php
...
...
...
Virtual hosts settings:
<VirtualHost *:80>
ServerName your_app_domain.dev
DocumentRoot "/path/to/your/app/web"
<Directory "/path/to/your/app/web">
Options Indexes FollowSymlinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/your_app_domain.dev.error.log
CustomLog ${APACHE_LOG_DIR}/your_app_domain.dev.access.log combined
</VirtualHost>

Outcome:
If you call http://your_app_domain.dev/app_dev.php it will use default DB settings in config but if you call http://your_app_domain.dev/app_test.php then it will use config_test settings.
