ICC has been conducting test cricket matches for women since 1934. We can also see some recent test matches for women.
But, there is no official ICC rankings were provided by ICC for women's test cricket. Rankings are available only to ODIs and Twenty20I matches.
Is there any particular reason for not having rankings for women in Test matches?
or
Does ICC has any limitations(no. of matches/ no. of nations) to provide ranks for particular format of cricket?
