The point leaves Wolves still bottom of the Premier League with eight points and 14 away from safety. But the result continues Wolves' improving form since the New Year.
Edwards said afterwards: "A really solid performance, really committed and we showed a lot of spirit. Newcastle are obviously a very good team. I thought without the ball we had lots of control. When we had to attack we did, we looked a threat on the counter-attack.
"It was a really committed performance. People will look at results and think it has clicked all of a sudden, but performances were there before that.
"They have got very good players but overall the game went how we expected it to. I am really pleased with the clean sheet, we don't give much away.
"We are not there yet, we understand there is a lot of work still. The boys are with it, the crowd were with us all throughout the game.
"We are making some good steps forward."
