I love what I do for work.
What you’ll learn How I build software How this helps teams Techniques Tools Show a fairly complete approach
WHY?

Buildservers
Developer merges to mainline
Buildserver gets changes
Buildserver builds, runs all tests and notifies team
Test results are published to team and viewable by all.

Common resistance I can’t write unit tests because…
I have a UI WaitN, QTP, Selenium
Fixing someone else’s poorly written code Refactoring, training
I use a database The tricky part.
Databases – The tricky part Common Questions
How do I write unit tests when I require a database
How do I merge changes? How do I add default/test data? How do I update…
Buildserver Production site(s)
A decent answer
Use SQL scripts! Table View Procedures Key and Constraints Default Data Test Data
My one slide solution
Automated Build Server TFS
Auto Generate Database DumpDatabase/CreateDatabase
Automated Testing MSTest
Generating the scripts DumpDatabaseToSql.exe
Microsoft.SqlServer.Management.Smo
Generating the scripts (2)
Database Files All schema files in
revision control.
Creating the database
Another trick: Entity Framework
EdmGen2 http://archive.msdn.microsoft.com/EdmGen2
Unit testing with the database Boy Scout Rule
Leave the campground cleaner than you found it.
At least… leave it as you found it.
Finally… sort of… Wrap it all up in a build script.
MSBuild, NAnt….
I’m using MSBuild… But prefer NAnt.
