Software has expanded its reach to every aspect of our lives; it is no longer relegated to a confined area of deployed applications to execute a business task. Software is responsible for business processes, consumer purchases, transportation, communications, and devices that are always on and, in some cases, life-critical.
The tolerance for software problems, especially in the enterprise, has traditionally been quite high. It is widely accepted that software will experience problems. However, as software becomes a necessity in everything that is used, made, touched, and experienced, the stakes of making sure it has been properly tested at all levels are greater than ever. Software problems are now feared by consumers and business executives alike. The realization of the significance of testing and the conversation about it have rapidly moved from the practitioner to the executive.
Just as the role of software has changed, the complexity and necessity of validating its intended and actual use has undergone a transformation. Testing has changed from primarily validating a deployed application focused on business to being a comprehensive and critical part of the entire lifecycle. Today, testing lives in every phase of the lifecycle for all products and applications, regardless of scale and scope.
Today’s business executives must be able to guarantee working software that is free of defects to avoid compromising business, safety, or security.
