We have a dedicated QA team. Generally developers write unit tests while QA writes more integration level tests (mostly back-end focused). They do some exploratory manual testing while most of the repetitive work is managed with (brittle) UI automation tests. It is a lot of work to maintain all of the tests that we have. However, we have an incredibly good track record of releasing on time and critical bugs are rarely introduced.
