Anecdotally, I like that separation because in absence of it working with any large-ish project (which most real life projects are), it'd get super hard for my brain to pick out tests even if they all had certain prefix/nomenclature.
Caveat: I use IntelliJ and I just jump to tests using CMD+SHIFT+T shortcut so not necessarily a generic example.
