Women's Test cricket is the longest format of women's cricket and is the gender equivalent to men's Test cricket. Matches comprise four-innings and are held over a maximum of four days between two of the leading cricketing nations. The rules governing the format differ little from those for the men's game, with differences generally being technicalities surrounding umpiring and pitch size. Far fewer women's Test matches are played each year than women's One Day Internationals, with the international calendar revolving around the shorter format of the game. The first women's Test match was played by England women and Australia women in December 1934, a three-day contest held in Brisbane which England won by nine wickets.
Women's Test cricket is subject to the Laws of cricket, with a number of variations and refinements, which are set out in the ICC's "Women's Test match playing conditions" document. For the most part, these playing conditions are very similar to those set out for men's Test cricket. Matches are played between two teams of eleven players, across up to four innings. Test cricket can have three results: a tie, a draw, or one team wins.
The primary, and most noticeable, difference from the men's game is that women's Test matches are played over four days, rather than five. However, the players are expected to fit more overs in per hour in the women's game than the men's: 17 as opposed to 15, and so a full day's play in a women's Test match should include 100 overs, rather than 90. The cricket field has smaller dimensions; the boundaries must be between 55 and 70 yards (50.29 and 64.01 m), in contrast to the 65 to 90 yards (59.44 to 82.30 m) required in men's Tests. As well as playing on a smaller field, the women use a smaller and lighter ball than their male counterparts; the Laws of cricket dictate that women should use a ball that is between 4 15⁄16 and 5 5⁄16 ounces (139.98 and 150.61 grams); which could be up to 13⁄16 ounces (23.03 grams) lighter than the ball used by the men. The Umpire Decision Review System (UDRS) is not available in women's Test matches, though umpires are permitted to ask the third umpire to check television replays in certain cases.
