Rovers have won all of their preseason games so far, beating York, Halifax and Hunslet, but Griffin feels Sunday’s game will give a truer indication of where Fev currently stand.
“We are not reading too much into our unbeaten run at the moment,” said Griffin.
“The two teams we have played in recent weeks – although they have thrown some good stuff at us – are from the division below.
“This week is going to be a good test for us, going up against a Super League team.
“I think it will give us a key indicator in terms of how we are progressing.
“Wakefield train five times a week and make use of fantastic facilities here at Featherstone while doing so, so it will be a big ask for our boys to match them.
“But I am really confident in the squad that we have got this year. There is plenty of Super League experience across the board and we have some quality young talent in there too.
“Apart from one extra training day, we are pretty much a Super League outfit ourselves, to be fair.
“If they send close to a full-strength squad, it will give us a good account of where we are at and will help us become more ready for the first game of the regular season.”
