Whey they're done, they Integrate them
Everythingbreaks!
SCENARIO (COMMON)

4. That awkward moment near the end of the project
when everyone realizes that none of their classes
interoperate correctly
INTEGRATION HELL

5. Integration HELL is extremely risky for a project
Difficult to determine how long it will take to
resolve the integration problems
Exceedingthebudget
Exceedingtheschedule
INTEGRATION HELL

6. Originated form eXtreme Programming (XP)
Mitigates risks associated with integrating software
Avoids integration hell
Integrate early and often
CONTINUOUS INTEGRATION (CI)

Fast and efficient

10. Benefits of a CI Server
Developers might forget to run the tests
Dont breakthebuild
It might take too long to run the tests
We might need to test the code in
various environments
Differentarchitectures(32-bit/64-bitIntel,ARM,PowerPC)
Differentplatforms(Windows,Linux,Mac,Solaris,HP-UX,AIX)
BENEFITS OF A CI SERVER

11. Reports provide useful insights to the team
Can track metrics line line coverage
Percentageoflinesexecutedbytheprogram'stests
Can run all sorts of utilities on your code
checksyle,findbugs,...
Can deploy automatically

12. Install Jenkins
Set up a git server: (Can even use GitHub)
