Hello, this is a simple challenge to test your skills on Symfony, PHPUnit and Cache.

You will see that we have a Controller\CustomerController. It basically gives you the following capabilities:

• Create multiple customers by sending an json to /customers/ endpoint
• Delete all customers
• Consult all customers

So what do you have to do?

• We want you to obtain the reponse of GET customers method from a Cache Server.
• Since you know that this information is immutable until someone hits POST/DELETE customer methods, you shall not hit the Database if cache information is available.
• Make Unit and Functional tests to ensure everything is working fine.* To let the things a little bit interesting you will have to implement an failover: If Cache Server goes down, you have to hit the Database and this needs to be transparent to our end user, not an Error page!
• You will recieve a thumbs up for good Commit Messages and SOLID knowledge.

• PHP 5.4
• MongoDB driver
• Mongo 2.6
• Redis 3

• $ git clone [email protected]:easytaxi/interview-cache-failover.git
• $ cd interview-cache-failover/
• $ composer install
• $ php app/console server:run
• Open http://127.0.0.1:8000/customers in your browser (check if everything is fine)
• You can test your database operation by doing a POST into /customers/
• $ curl http://127.0.0.1:8000/customers/ -X POST -d '[{"name":"leandro", "age":26}, {"name":"marcio", "age":30}]'
• Then check your MongoDB collection to see if customers were created or just call the action
• $ curl http://127.0.0.1:8000/customers/

• Install PHPUnit
• In projects root run: phpunit
