Testimonials

We have been working with the BB&T account on Salesforce Data Integration for over a few months now and are delighted with the work carried out so far. BB&T intends to integrate all the downstream applications with Salesforce and this change requires a number of data integrations to be validated and all data testing needs to be of the highest quality, which is what we got by using DataTestPro developed by the QE&A CoE team. Using the tool we performed Data testing that spanned across varied transformation logic like string operations, numerical operations, logical(if/then) transformations .The Organisation understands the high standards that our company have and the DataTestPro tool is very efficient in delivering well within time limits. It helped improve our data testing productivity and realize significant cost and effort savings. I would highly recommend using DataTestPro as a data test automation solution - Esakki Muthu Doss Ramiah, BB&T Testing Manager Our client is amidst major data migration project where millions of revenue worth of data is being migrated from legacy system to a newly built platform. Each migration has tens of thousands of data tables each having hundreds of field. These were initially checked by spot checking which were leading to defects as well as lower confidence levels in testing as the testing was not exhaustive. With the addition of Data Test Professional, the testing has been extremely thorough and has cut down our repeat testing efforts by half. The client is extremely happy with tool and is now looking to expand its use out of our current implementation to other domains of data testing.
