DECISION TABLE TESTING – H2KINFOSYS
Decision
table testing is one of the test design techniques for black box testing or
specification based testing. The different possible input and output logical
conditions are identified for testing. Software testing can be classified as
white box testing and black box testing. The test
design techniques are used for both white
box testing and black box testing to design
the test conditions.
Decision
Table testing:
Decision
table deals with the combination of various inputs in order to produce the
expected output. Basically it involves the conditions to the data while
testing.
For example: A customer
feedback software is to be developed for a restaurant. After ordering food
customers provide the rating based on two things firstly food serving time and
taste of food. Whether the ordered food is served on time and whether it tastes
good? The customers can choose between two different conditions and we could identify
how many combinations we can make out of these two conditions for testing the
software.
The food may be served late
and its not tasty.
The food may be on the time
and its not tasty
The food is not on time but
its tasty
The food is on time and its
tasty.
Based on these conditions
you make some decisions whether the restaurant is good or bad and take
some actions based on this decisions.It is also called as cause – effect table
which involves logical diagrammatic representation which helps to derive the
decision.

university allocates the space to students on its server to store assignments.
The students can login using their student accounts. The student can continue
to store new files if they have not used up existing spaces. Identify the

the 3 functionalities available for testing. Use decision table
technique. CLICK
