2
Outline

• Continuous Integration
• Continuous Builds
• Continuous Tests
• Tools for Build, Test and Integration

3
Continuous Integration

• Traditional Integration methods
• Integration before the end of iteration
• Weekly integration
• Big Bang Integration
• Too many bugs and too little time to fix them

4
Continuous Integration

• CI principles
• Integrate more often
• Daily, Hourly
• Integrate continuously
• After completion of every task

5
Continuous Integration

• Advantages
• Integration becomes important if you integrate
  small and simple tasks
• Developers get a better overview of the system
  and its architecture
• In turn, integration becomes easier

6
Continuous Builds

• CB principles
• Build your changes locally before checking in
• If it doesnt compile, dont check it in
• Build the entire system from scratch on a
  dedicated build server

7
Continuous Builds

• Advantages
• Reduces the problems with files that arent
  checked in
• Reduces problems with debug and release versions
• In an integrated and stable stage builds can
  serve as demo-versions

8
Continuous Tests

• CT principles
• Test your changes locally before checking in
• If it doesnt pass the tests at 100, dont check
  it in
• Start the system and run the full test-suite
• Advantages
• Reduces bugs
• Increases the chance to have a running system at
  every time

Build Tools

• Cruise Control
• Java based for continuous build process, free,
  open source, it automatically builds on
  development servers not on developers desktop
• Ant
• Pure build tool from Apache, it builds .jar file
  and you see build successful message
• Maven
• A lot functionality out of the box, from
  Apache, can be important as plug-in into Eclipse
• MS Build Engine
• Build Management Project Management
• (a BBA student may guide)

10
Test Tools

• Maven
• Runs xUnit test suites
• xUnit
• Suite of Test Frameworks for several languages
  (Java, C, C, Perl, .)
• FindBugs
• A static code analysis tool

Integration Tools

• Subversion
• Apache Subversion (often abbreviated SVN) is a
  software versioning and revision control system
  distributed as free software under the
  Apache License
• CVS
• CVS is a version control system, an important
  component of Source Configuration Management
  (SCM)

  from Fahad)
