- In software Testing Test Design is the important for
software testing itself, to reduce the testcases as minimum as possible and
find more defects
- There is a tool called http://testersdesk.com/ - TestersDesk.com
which is used specially for Test Design and Test Data Generation Tools, There
are different types of tools which are used to reduce the testcases into little
number, I can explain clearly with good example
PairWise
TestCase Generator
This
tool will be useful in the situations where several parameters exist each of
which take several values resulting a high number of Test combinations, to
reduce that combinations into a little number we are using this tool.
It
will cover almost 80-90% of Test coverage.
It
will cover single fault determination.
For
Example:
Net
connections: Tata, Reliance, Airtel
Browsers:
IE6, IE7, IE8
Platforms:
XP, XP2, XP3, Vista
Ram:
1GB, 2GB, 3GB
Manually
if we generate the combinations it will generate 108 pair combinations like
1) Tata-IE6-XP-1GB
2) Reliance-IE7-XP2-2GB
etc
but our pairwise TestCase Generator Generates
into a little number 13 which is very simple for the Tester to test those 13
pair combinations.
PairWise
Testing can be used mainly when we have to find critical defects.
