I delivered this talk in SiliconIndia's SoftTec 2012 on 14th July 2012. I introduce Behavior Driven Testing (BDT) with a couple of examples, the different ways of writing the tests in Imperative and Declarative style, the value proposition of BDT, and how BDT can help you build a very good safety net using Test Automation suite.

15. Expected
Func/onality:
The
customer
should
be
able
to
withdraw
money
from
his
account
via
an
ATM
machine

16. BDD
Example:
Given
the
account
has
balance
of
5000
When
the
customer
requests
1000
Then
the
account
is
debited
by
1000

17. BDT
Example:
Given
the
account
is
in
credit
And
the
dispenser
contains
cash
When
the
customer
requests
cash
Then
ensure
the
account
is
debited
And
ensure
cash
is
dispensed
And
ensure
the
card
is
returned

18. New
Expected
Func/onality:
The
customer
should
be
able
to
withdraw
money
from
his
account
only
if
his
card
is
valid

19. BDT
Example
-­‐
updated:
Given
the
account
is
in
credit
And
the
card
is
valid
And
the
dispenser
contains
cash
When
the
customer
requests
cash
Then
ensure
the
account
is
debited
And
ensure
cash
is
dispensed
And
ensure
the
card
is
returned
