You are right in your thinking as test match depends on wicket so good field plays a big role in run out and cash out. Overs are not a problem in Test matches because here wickets can be played all day so it is more important for the opposition to bowl and field well to take quick wickets and prevent them from scoring big runs like four & six. And if the batsmen can stay on the field for a long time and don't miss single runs then they will be able to collect a lot of runs which should be at least 300+.
It's much important for winning a Test match in cricket to necessitate a strategic blend of gameplay, resilience, and adaptability. A successful team must excel in both batting and bowling, understanding the intricate details of the game. Batting-wise, batsmen must form partnerships, withstand challenging spells from opposition bowlers, and capitalize on scoring opportunities.
