T-Shaped Agile Teams

In small Scrum teams, it’s common for people to share roles such as Scrum Master / Tester / Dev but in a lot of cases there are conflicting interests. How can a Tester adequately test when as a Scrum Master the highest priority is assisting the team to deliver? This is an experience report from when the presenter was working at a start up with a shared role of Tester, Scrum Master and DevOps and how the role affected her thinking when context switching to different roles. For example, how on more than one occasion, the skepticism of the Tester had to pull the optimism of the Scrum Master back to reality and then how the results of the testing were overshadowed by the need for the team to deliver. The T-shaped person is often looked upon as an incredibly valued member of the Agile team but on becoming T-shaped has the person become a watered down version of their primary role?
