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+.
Playing the test match requires a lot of patience for the player to stay patient to score runs successfully. Those who watch the test match also have to enjoy the game with a lot of patience. Test match players have to stay on the field with a lot of patience who enter the field to bat, if they enter the field to bat thinking about runs, they can never survive on the field. To survive on the field, you have to bat with patience.
Yes ,I agree with you. Patience is key to success in test matches. But in opinion, player should play his natural batting. Muhammad Younus was a good test player. He played in every difficult situation and won many matches for team. But in comparison, Shahid Afridi was not ball stop player but his career is brilliant. He is respected whole the world and he made many records in test matches but after he played only T20 and ODI matches. Kumar Sangakara was also a good player ,he made many records and this type of player is very rare.
In my opinion, players should focus on their strengths
In Test matches, a player who gets excited with the bat and tries to hit every ball and is anxious to hit fours/sixes will get out very quickly and will not be able to bring good runs for the team. In the first Test match, Bangladesh played very well against New Zealand and won the match by a huge margin of runs. Winning a match by 150 runs in a Test match is a big thing. Because there is no over limit, both teams can play as much as they want by save wickets
