[TIP] py.test deprecating yield tests

[Ronny Pfannschmidt]

Hi Randy,

the Problem with yield tests is, that they execute test code and setup
state at collection time, wich is a massive source of errors in any
complex case and just barely works in the simple case

back when py.test collected and executed tests as it discovered them,
that was fine, but its been quite a while now since py.test switched to
collect first, then execute (around the 2.0 release i think)
