8.10 The Important Economic Dimension 307
independent test code as a result of the knowledge based inference of a test
suite.
One of the next challenges in testing is to define the test data. This process
has to be carefully analysed since generating random test data may lead to
redundant test cases and hence produces waste of execution and extra workload.
The best idea is to intelligently generate test data so that the test data
value space is covered efficiently with a small subset of values and in parallel
to remove test redundancy. In this context a novel approach based on
data fuzzing with TTCN-3 is being developed. Fuzz testing or fuzzing is a
well-established automated and efficient black-box testing method for finding
software flaws.
8.10 The Important Economic Dimension
Interoperability will not be improved without the motivation and support of
market stakeholders. Motivating and involving market forces cannot be done
without taking account economic dimensions. Without proper consideration of
these factors, we will not succeed improving interoperability and this is often
the reason why some technology stays isolated without world wide support
as nobody as answer the questions of cost of testing, time to market, cost of
tools, etc.
Cost of testing: Money spent on testing a product is an investment for a
company. When they invest money on something, they normally expect a
good return on investment. Investment on testing will impact on the market
price of product. This cost includes money spent on certification programs,
test house fees, purchase of test tools, etc. It also includes the money spent on
correcting errors found during testing.
Time of testing has impact on the time to market and market price of a
product. Time of testing is the time spent on testing a product. Using test tool
to automate the test will considerably reduce the time spent on testing. We can
also consider the time to develop the tests which is often under estimated.
Test tool: Cost of developing of test tool is often very expensive and can
rarely be beared by one single company. There is therefore need to share
