It is easy enough to get updated tables like this:
(All these tables are updated to Dec 3, 2019):
Most Tests (120 and above)
Current players with the most Tests are Anderson (149), Broad (134) and Amla (124).
Another table which is easy to create:
Most Tests as Captain (40 and above):
Kohli is the only current player here. He has captained in 53 Tests and has still to overtake Dhoni (60). He overtook Ganguly (49), Gavaskar and Azharuddin (47) not long ago.
But this one needs a little more work with Excel:
Most Tests NOT as Captain (105 and above):
Current players here are Anderson (149), Broad (134) besides recent retirees de Villiers (111) and Amla (110). Note that some, like Tendulkar and Kallis, have captained for a few Tests but others such as Anderson and Broad have never captained. More about these cases shortly.
