Answer 1

A list of items that should be reviewed and considered when staring with database unit testing

• Each tester needs a separate database, in order to avoid interfering with activities of other tester/developer
• To have an easy way of creating a database to be tested (this is related to having a SQL Server database under version control). This is specifically useful when trying to find what went wrong if some tests fail
• Focus on specific areas and creating tests for a single module instead of covering all at once. Adding tests granularly is a good way to be efficient
• Make sure to provide as many details as possible when a test fails, to allow easier debugging
• Use one and the same test data for all tests

If test are implemented using tSQLt framework, the unit testing process could be complicated when dealing with a lot of databases from multiple SQL Server instances. In order to maintain, execute and manage unit tests directly from SQL Server Management Studio, ApexSQL Unit Test can be used as a solution
