Test cricket is the longest form of the sport of cricket and is considered its highest standard. Test matches are played between national representative teams with "Test status", as determined and conferred by the International Cricket Council (ICC). The 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 teams' playing ability and endurance. The name Test stems from the long, gruelling match being both mentally and physically testing.

The first officially recognised Test match took place on 15–19 March 1877 and was played between England and Australia at the Melbourne Cricket Ground (MCG), where Australia won by 45 runs. A Test match was held to celebrate 100 years of Test cricket was held in Melbourne on 12–17 March 1977, in which Australia beat England by 45 runs—the same margin as that first Test.
