Antonio Conte's side are coming off a morale boosting victory over AC Milan in the last round.
The 2-0 triumph in Turin lifted Juve to the top of Serie A, level on 11 points with Udinese after five games.
"We overcame an important test against Milan," Lichtsteiner said to www.juventus.it.
"It was an important victory for our morale but especially because we handed a convincing performance.
"That game allowed us to understand our true potential.
"But the tests are never ending in Serie A and now we must repeat that performance otherwise the victory against Milan would have served for nothing.
"The game in Verona against Chievo is an opportunity for us to show that we can play always with the same intensity that we displayed against Milan."
Juve will not take Chievo lightly with the Flying Donkeys having collected seven points from a possible nine in their last three games.
Moreover, Chievo, who are eighth in the standings, twice held Juventus to a draw last term and are determined to end the Bianconeri's unbeaten run this season.
"This is the strongest Chievo I have ever trained," Chievo coach Domenico Di Carlo said. "Many players go on the bench who are potentially first choice picks and we can still improve a great deal.
"I tell my players the same thing before every game. We work all week to win, now we're going on to the pitch to achieve it."
Di Carlo will have all of his players available for Sunday's game at the Marc' Antonio Bentegodi stadium.
