Test that woman, one who's given birth (6)
I believe the answer is:
mother
'one who's given birth' is the definition.
'test that woman' is the wordplay.
'test' becomes 'mot'.
'that woman' becomes 'her' (I've seen this before).
'mot'+'her'='MOTHER'
(Other definitions for mother that I've seen before include "Be overprotective" , "Fuss over" , "- - 7 across, pantomime" , "One who pours the tea?" , "She gave birth to her Tom" .)
