[split] MS SQL server driver?

Setting up and running tests for the drivers should not be difficult if you already have a connection to a SQL Server instance configured.

The main issue with testing is with setting up the automated tests for Travis in the CI4 repository on GitHub. For some database platforms, there's a fairly well-documented procedure to configure Travis to start a database instance to use for testing. However, of the many CI3 database drivers, MySQL, PostgreSQL, and SQLite3 are the only platforms covered in that document.

Once you get beyond the built-in platforms, very few people have documented the process for other database platforms, and it appears that the process can be significantly different for each platform.
