I don’t see the test format as thriving. It often seems the players don’t have the patience anymore to play it, losing games that they could have drawn if they had the perseverance needed to try so.

(For those who don’t know cricket: if your opponent is outscoring you heavily, there’s no way to win the game, but by playing defensively, there still is the possibility of “not losing” the game (called a draw. That’s different from a tie, where both teams score the same number of runs. Ties are extremely rare (about 1:1000 matches. See https://en.wikipedia.org/wiki/Tied_Test), draws fairly common (about ⅓ of all test matches)). Part of the charm of test cricket is that trying harder to win a game also increases the risk of losing it, so teams have to make educated guesses as to whether to pursue that)
