LEARNING
¨ Test each part thoroughly
¨ Unit
¨ Test ways of working together
¨ Component Integration
¨ Test how it all comes together
¨ Functional
This is how the parts becomes a Pen!

But …. what about the
things you do not see?

LEARNING CONTINUES …
¨ Test the Non Functionals
¨ NFRs
¨ Test the 3rd-party integration / interactions
¨ Integration

How does this
apply to Software?

LEARNING CONTINUES …
¨ Test each part thoroughly
¨ Test ways of working together
¨ Test how it all comes together
¨ Test the Non Functionals

CONTINUOUS INTEGRATION (CI)
”… 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, ThoughtWorks Chief Scientist
