What is Continuous Integration? “Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily - leading to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible.” –Martin Fowler

An XP technique Pair programming Planning Game Test Driven Development Whole team Continuous Integration Design Improvement Small Releases Coding Standards Collective Code Ownership Simple Design System Metaphor Sustainable Pace

Continuous Integration Scenario 1. Developer checks out latest source code from repository. 2. Developer makes changes (hopefully with TDD). 3. Developer checks out latest source again to look for conflicts. 4. With conflicts resolved, developer checks in changes to repository. 5. CI system, detecting changes, checks out source code on an integration server. 6. CI system builds. 7. CI system runs automated tests. Demo: Alice

Is CI just another unpracticed trend? Who in the room does CI? Nant and CruiseControl.Net widely used.

Nant Overview Targets contain Tasks (think functions) Tasks perform actions Targets may have dependencies Properties are variables Demo: basic file usage

Important Nant Tasks Nunit Copy Mkdir, rmdir Foreach Zip, tar Functions exist as well Also: ability to pass in parameters at command line Show: Nant documentation

CruiseControl.Net Overview Suite of apps for Continuous Integration: CCNet Server CCNet Web Dashboard CCNet Tray Allows reporting via XSL. Demo: Start server, show web dash

General CC.Net Flow ccnet.exe nant nunit fitnesse coverage fxcop xml result merge xsl Source control

Important CCNet Config Elements Source Control Tasks Publishers Triggers Nant Merge Demo: ccnet.config
