International cricket
Most games are played as parts of "tours", when one nation travels to another for a number of weeks or months, and plays a number of matches of various sorts against the host nation. The ICC also organises competitions that are for several countries at once, including the Cricket World Cup & ICC T20 World Cup.
Test cricket
There has been no World Cup for Test cricket conducted thus far by the ICC, since it is the longest format of the game, due to which the Championship might go on for years together. However, as of late, the ICC is holding discussions to conduct a World Test Championship over a span of 2 years (starting its first Championship from 2019–2021), after failing to execute their plan of conducting this tournament twice, once during 2013 and another time during 2017. The schedule for 2019–21 Test Championship is a set of typical bilateral series in various countries put together, where one team is the host and other team is the visitor. The length of the series would vary between 2 matches to 5 matches. The result of each match carries a weighting of the points depending upon the length of the series: a single match in a 5-match series will account for 20% of the series points, while a match in a 2-match series will account for 50% of the series points.
