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

Continuous Integration• CI principles

• Integrate more often: • Daily, Hourly

• Integrate continuously:• After completion of every task

Continuous Integration• Advantages

• Integration becomes trivial if you integrate small and simple tasks• Developers get a better overview of the system and its

architecture • In turn, integration becomes easier

Continuous Builds• CB principles

• Build your changes locally before checking in • If it doesn’t compile, don’t check it in• Build the entire system “from scratch” on a dedicated build

server

Continuous Builds• Advantages

• Reduces the problems with files that aren’t checked in• Reduces problems with debug and release versions• In an integrated and stable stage builds can serve as demo-

versions

Continuous Tests• CT principles

• Test your changes locally before checking in• If it doesn’t pass the tests at 100%, don’t 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 developer’s 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)

Test Tools• Maven

• Runs xUnit test suites• xUnit

• Suite of Test Frameworks for several languages (Java, C, C++, Perl, ….)

• FindBugsA static code analysis tool
