If you write code to SQL Server then you might be interested in this: at the end of 2017 I wrote a tSQLt tdd training course which has helped over 300 people learn both tSQLt and how to apply TDD practices to their SQL Server T-SQL development, you can join the course at https://courses.agilesql.club. The course is free if you are happy to wait 10 weeks to complete it, with 1 lesson being made available per week - if you are in more of a hurry or you would like to help support the project you can purchase the course which makes it instantly available to you.
I had a lot of fun yesterday presenting my talk on how to go from not having your database in version control to deploying to a CI database, running unit tests and generating deployment scripts for a QA/Prod database so effectively how to build a fully functioning continuous delivery process for SQL Server databases in less than an hour (my wittering was about 40 minutes and the demo just over 10).
The slides are now available:
If anyone has any questions or wants to know more please feel free to ask :)
