Othogonal Array Testing to my understanding is not exactly
a testing type but a technique to reduce the testing effort
by reducing the Testcases, identifying the repetition of
pairwise combination.

Answer / yogesh

The Orthogonal Array Testing Strategy (OATS) is a
systematic, statistical way of testing pair-wise
interactions. It provides representative (uniformly
distributed) coverage of of all variable pair
combinations. This makes the technique particularly useful
for integration testing of software
components (especially in OO systems where multiple
subclasses can be substituted as the server for a
client). It is also quite useful for testing combinations
of configurable options (such as a web page that
lets the user choose the font style, background color, and
page layout).

Answer / kavida

Orthogonal Array is a Testing Design Technique where u can
give 90% Test Coverage.Here Functionalities are seperated
into "Factors" and "Levels" and out put will be in the form
of "Experiments".Its a misunderstandindg that the no of
Test cases will be reduced always in Orthogonal Array.It's
not the way always.It gives the effective Experiments/T.C
to be executed ,some times it may list more no of T.C than
u identified manually.
Objective:
Reduce COST,REWORK,TIME
Increase Productivity
MAX Test Coverage

Answer / nirmala raveendran

In OATS we reduce the test cases by eliminating the
repeated pair combination still ensuring maximun test
coverage, this technique is not used for a simple project,
applied for complex projects when test has to be conducted
across varios OS, browsers and processors within a limited
timeframe. We arrive at reduced number of test cases and
ensure cost effective, efficient results. Instead of
running all the scripts, we assure that the resulting
scripts (reduced by applying OATS technique) when executed
would satisfactority asssure that the product works right.

Answer / ratnadeep jadhav

orthogonal actually means the type of experiment in which
individual coluoms are "orthogonal to each other.It is not
actully testing, it is technique to reduce different
testcases.orthogonal testing is stastical and systematic
way of testing.It has four steps,formulate the problem-plan
the expriment-analyse the result-finally comfirm the
improvement.After this if we get the desired objective then
adobe the new result otherwise again formulate the new
problem.Orthogonal is generaly applied to improve "Quality
and Productivity" and further test efforts...

Answer / k.chandra sekhar

a) Orthogonal array testing is nothing but that is 90
degrees testing
b) That is the when all testing requirements are
cleared the test is orthogonal array testing.
c) In all test case are maximum passed
d) It is very good testing
e) Here use the test data through the array
f) So then the application is more quality
