Unit testing, everyone talks about it and wants to do it but never gets around to actually start testing. Complex spaghetti code and time / budget pressures are often the reasons why nobody dives in and gets started with testing. But when the application breaks, and people loose money or worse it's often too late. In this talk I will take you on a journey with real examples that will show you how you can set up your tests, how to test complex situations with legacy spaghetti code, test web services, database interactions and how to gradually build a solid foundation to safeguard the core code base and everything around it. Don't you want to be confident when you walk out the office?

the
extra
work?
• Your

are
fully
tested,
no
need
to

it
yourself
again
• The
connec6ons
are
expensive
and
delay
your

• Your

that
