Many believe that regression testing an application with minimal data is sufficient. With big data applications, the data testing methodology becomes far more complex.

Finding issues before deployment and saving your company’s reputation—and in some cases preventing litigation—are critical. Jason Rauen presents an overview of the architecture, processes, techniques, and lessons learned by an original big data company. Detecting defects up-front is vital. Learn how to test thousands, millions, and in some cases billions—yes, billions—of records directly, rendering sampling procedures obsolete. Save time and money for your organization with better data test coverage than ever before.
