The Aussie coach made several changes to his team for the game at Twickenham but England still managed to get the job done in front of a packed crowd.
However, they did struggle on occasions and there was a gap of 31 minutes between points either side of half-time.
A late flurry of tries saw them pull away in the end as they recorded another autumn international win following earlier victories over Argentina and Australia.
Jones openly admits his players need to learn and believes Saturday's victory will help them become a better team in the future.
He told reporters: "I probably would've been disappointed if they didn't struggle.
"That's the sort of examination we wanted, particularly after playing Australia. When you're playing against a side you're supposed to beat by a big score... the mindset you need for that sort of game is something you only get by experience.
"We started the game well and then thought the game was going to flow and going to be easy.
"We want to find out these things now, what players struggle to do. And then we can help them and they can help themselves fix it.
"You don't want to find these things out in the 60th minute of the game against Tonga in Kobe [during the 2019 World Cup opener], that some players aren't up to it."
