11. A non-transitory computer readable medium comprising a set of computer executable instructions, which, when executed by a processor causes the processor to perform steps comprising: generating one or more test cases and one or more test scripts, for execution of the test cases, based on a data mapping file associated with a source data repository and a target data repository; executing the test scripts on the source data repository and the target data repository; generating and outputting a test results report indicative of the outcome of the execution of the test scripts; receiving one or more online analytical processing (OLAP) parameters and generating an OLAP cube report for the target data repository based on the parameters, wherein the OLAP cube report is summarized across one or more dimensions based on contents of the target data repository; comparing the OLAP cube report and another report, which is to be tested, based on the test cases to determine when one or more fields in the OLAP cube report do not match one or more corresponding fields in the another report; and generating and outputting a comparison report based on the comparison, wherein the comparison report indicates the one or more fields of the OLAP cube report, when the determining indicates that the one or more fields in the OLAP cube report do not match the one or more corresponding fields in the another report.

The non-transitory computer readable medium as claimed in claim 11 , wherein the computer executable instructions, when executed by the processor, further cause the processor to perform one or more additional steps comprising; analyzing the another report to determine the dimensions of the another report; and generating the OLAP cube report with dimensions corresponding to the determined dimensions of the another report.
