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

Continuous Integration Scenario1. 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.

Is CI just another unpracticed trend?Who in the room does CI?Nant and CruiseControl.Net widely used.
Nant OverviewTargets contain Tasks (think functions)Tasks perform actions
Targets may have
dependencies
Properties are variables
<target name="config"> <property name="build.dir" value="CruiseControlDemoProject\bin\Debug"/> </target>
<target name="clean" depends="config"> <delete dir="${build.dir}"/> <mkdir dir="${build.dir}"/> </target>
Demo: basic file usage
Important Nant TasksNunitCopyMkdir, rmdirForeachZip, tarFunctions exist as wellAlso: ability to pass in parameters at
command line
