How to do testing using cassandra in my nodejs application?

I am working on a nodejs application. The database used is cassandra. We are using https://www.npmjs.com/package/dse-driver.

I am trying to understand how to write tests for the application. I am specifically confused about how to keep my test database separate from development database. Can we create and destroy test databases on the fly like Django? How are test cases for cassandra and nodejs written? What are the best practices for the same?
