Test cricket is the form of the sport of cricket with the longest match duration, and is considered the game's highest standard. Test matches are played between national representative teams that have been granted Test status, as determined and conferred by the International Cricket Council (ICC). The term Test stems from the fact that the long, gruelling matches are mentally and physically testing. Two teams of 11 players each play a four-innings match, which may last up to five days (or longer in some historical cases). It is generally considered the most complete examination of a team's endurance and ability. The first officially recognised Test match took place between 15 and 19 March 1877 and was played between England and Australia at the Melbourne Cricket Ground (MCG). In October 2012, the ICC recast the playing conditions for Test matches, permitting day/night Test matches. The first day/night game took place between Australia and New Zealand at the Adelaide Oval, Adelaide, on 27 November – 1 December 2015.
