Building good habits is an important part of an effective Scrum team. Habits are a form of automation: The more basic processes we can automate, the more we can focus our energy on hard things. The Scrum process, with its focus on rituals, helps us by providing a framework for collaboration and making it second nature.

Testing can get complicated when each project is using a completely different toolset, language, and reporting status, with different measurements and formats. Testing is a reaction to context and what we encounter, so how we test cannot be standardized. What we can standardize is the stuff that surrounds the testing.

Scrum is a fairly minimal agile process framework that you can adapt to work best for your team. But adaptation works best once the team has internalized the principles and values of the Scrum process, and that takes practice. In other words: Before you start to adapt Scrum, first try fully adopting the framework.
