Regression testing is not a new concept. However, with the advent of NFV, regression testing is undergoing a rapid transformation allowing Cloud and DataCenter operators to embrace virtualization technologies as part of their testing and development cycles. Virtualization of the regression testing platform can help decrease the number of bugs and increases code coverage in testing, thus reducing the time-to-market for hardware or VNF products. Virtualizing regression beds today will enable users to test future offerings such as VNF easier. This solution brief looks at the pros and cons of automated, virtualized regression test beds.
