Testing is becoming a structure-defining part of IT production, due to three major factors. First is the initiative taken by standardisation bodies to define various tests and consider how they should be managed and integrated. These standards go with certifications that have become essential throughout the world of software. Furthermore, within businesses, testing is scheduled increasingly early, regardless of the method adopted. They guarantee the quality of the software, the reliability of the applications, their long life, and as such help reduce risks and maintenance costs. The third factor is the arrival of a variety of testing automation software on the market. However, the excessive number of solutions is making choices harder for IS departments. Testers have now become key players in all IT teams, including development, project leadership, and maintenance. This revolution, however, is not complete; in the future, project managers will rely on testing similar to how executives rely on management control.
