Women's Test cricket is the longest format of women's cricket and is the female 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 field size. 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. A total of 144 Women's Test matches have been played. Far fewer matches are played each year in favour of Women's One Day Internationals and Women's Twenty20 Internationals, with the international calendar revolving around the shorter formats of the game. Playing conditions 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 , in contrast to the 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 and ounces (139.98 and 150.61 grams); which could be up to ounces (23.03 grams) lighter than the ball used by the men. The Decision Review System (UDRS) is now available in women's Test matches, also umpires are permitted to ask the third umpire to check television replays in certain cases. As women's tests are played over four days the minimum lead to impose a follow-on is 150 runs, compared to 200 in men's test
