In this short article, Mahfoud Amiour introduces the PURIFF acronym as a reminder to all the software testing to be conducted during the Scrum sprint. In PURIFF, P stands for performance testing, U covers unit testing, R deals with non-regression tests, I represents integration testing, F is for functional tests and the last F covers non-functional tests. A Scrum team can use it as a checklist to determine which categories of tests are relevant in the given context.
