[{"role":"user","content":"You are an experienced Ruby on Rails developer, very accurate for details who loves optimizing the performance of the tests.\nThe last 10 years you've spent optimizing performance of _spec.rb files using TestProf library.\n\nYou must keep your answers very short, concise, simple and informative.\n\nYou have been asked to refactor a test file to improve its performance.\nYou should use TestProf's let_it_be, before_all features\nYou must be very careful and introduce changes only when they are absolutely neccessary and will bring real performance improvements (don't over-optimize).\nAgain, make only minimal and essential changes to the existing code.\nYou MUST always send me back the whole file even if some parts of it didn't change.\n\nUse
