The role of QA, QE, or SDET is becoming less efficient in the fast-moving world of modern applications and continuous delivery. As manual testing was replaced by automated testing, software engineers specializing in testing obtained development skill sets. Being able to both develop and write tests concurrently for modern applications leads to improved engineering productivity and a team-wide commitment to quality. Angular in particular provides excellent tooling to make development and testing seamless. By eliminating specialized roles, developing applications can be fast and effective, because the team owns all aspects of the software development life cycle
