Overview Change LogThe Nova framework is a PHP 5.5+ MVC framework. It's designed to being lightweight and modular, allowing developers to build better and easy to maintain code with PHP.To this end Nova does not come with lots of built in libraries/helpers or modules instead, it's left to the user to Deci De they want to implement, this allows freedom to design and build how do you see fit.The base framewo

Test classification in OpenStack Test categories in OpenStack can be divided into the following types:1) unit test (small test/unit tests) Unit tests are stored in the code library of each component. For example, unit tests of nova are stored in the nova/tests directory. Unit Tests are mainly aimed at testing the source code and testing the code at the function level.
