Answer 1

Some of your questions cannot be answered riefly, so I chose the ones that can be:
<i>1 explain me the various testing phases they do in sap</i>
Unit Testing - Developers test before going to QAS to test small samples of data from Source to Query and make sure they match the transformations.
Integration Test - Developers test to make sure all the new landscape can work together with respect to laoding, transformation and queries.
Regression Test - Developers test to make sure current Objects do not aversely affect existing developemnt in landscape.
User Acceptance Test - Business USers test in QAS.
Business Integration Test - business tests in QAS.
<i>2 How they do testing in cubes ( like CO-PA cubes
0COPA_C01, 0COPA_C02 and FI-AR ODS object 0FIAR_O03)</i>
Refer above
<i>3 what testing they do in development phases</i>
Refer above
<i>4 can you explain exactly like the steps followed for
testing in reporting ( GIVE SOME EXAMPLE)</i>
I don't work a lot on queries, so wait for a front end guy to explain these. Clients that I worked with will usually have a different person doing query testing.
<i>5 Performing cross browser functionality testing on
multiple versions of SAP r/3</i>
<i>6 How do you Create Test input requirements and
prepared the test data for data
driven testing</i>
Didn't work on this much
<i>7 how do yo Performe GAP analysis</i>
This cannot be explained easily. Its a process of looking at requirements and while developing, identify what cannot be accomplished in this project for various reaons (Money, time, developer resoueces, etc) and working on a proposed solution for next phase, etc.
