Infosys Cloud Testing practice, part of Infosys Cobalt, designed and developed a one touch automation tool, Automated Data Comparator (Auto DC) for the data warehouse testing program. The solution was developed using the technologies below:
This framework model was built for the following comparisons:
Zero defect delivery: 100% test coverage leading to zero production defects, Increase in test coverage which helps identify defects early, Incorrect data in production will lead client to report wrong values to the regulatory board and also it has a cascading impact of client paying penalties for being non-complaint.
High quality deliverables: Completely reusable components that can be customized as required with minimal effort, Flexibility to generate detailed test summary report after each test run.
Faster Time to market: Up to 80% effort saving in execution cycle for faster time to market
“At NAB, Infosys implemented a solution named Auto DC (Automated Data Comparator) for validation of data across heterogenous source systems. Auto DC was developed to communicate between on-premises and cloud-based assets and to ensure both source and target data is identical. This framework generates a comparison report with status based on the test results and enables us to identify defects earlier. It has reduced of test execution effort by 80%, helping NAB go to market faster.”
