The World Quality Report 2012-13 found that while testing budgets have proven resilient, confidence in testing resources is lacking. Mobile testing in particular has not received sufficient priority, with only 31% of organizations currently testing mobile applications. New operating models such as cloud-based testing and Testing Centers of Excellence are becoming more established. The report also found a growing harmonization of testing practices globally, but that perceived quality of internal and external testing resources remains average. It recommends that testing be formalized in the application lifecycle, that mobility be fully integrated into testing, and that the diversity of testing skills be re-evaluated.
