Challenge: As the product is a vast product that provides so regression suite of this was very big. It was taking about 14 days to execute and with every release it was increasing. The main challenge was to keep regression suite comprehensive as well small so that it can be executed many time. Solution Emma was used to find code coverage of product code then redesign the regression suite.

3. The product was big product that provide a lot of functionality.
The Product was developed in Java language.
QA Team was using Rational Function Tool(RFT) for automation of
regression suite.

4. As the product is a vast product that provides a lot of functionality so
regression suite of this was very big.
It was taking about 14 days to execute and with every release it was
increasing.
Regression suite was not so efficient as it was not catching bug so
frequently.
Team was unaware of the amount of code coverage achieved with
automation test suite execution and what parts of application were
executed and what parts were not.
The main challenge was to keep regression suite comprehensive so
that it is likely to catch all the bugs introduced as well small so that it
can economically be executed many times.

5. EMMA tool was to be used to find out the coverage of Java based
applications.
EMMA was to be used on the server machine where the source code
of the application was executing.
RFT scripts were to be executed and got the source code coverage
details from EMMA tool.

blocks and lines were executed.eg
 Emma also provide help to identify the code which were executed and
which were not by showing these in different color.eg. for unexecuted code:

10. Conclusion
Emma can be used to know the coverage of both Manual and Automation
test suite. Emma can be used with both windows and web base
applications.
We can use Emma with any Functional Testing Tool to find the coverage of

the automation test suite
