Ms Suu Kyi's lawyers have concluded their final arguments in the widely condemned case against her on security charges.
A court official said her trial has been completed, although cases against three other defendants are continuing.
Journalists have been banned from attending the trial in Burma, which is also known as Myanmar.
However, a handful of foreign diplomats have been invited occasionally as observers.
A guilty verdict is widely expected, but it is not clear if any sentence will be announced on Friday.
'We have done our best and she is prepared for the worst,' Ms Suu Kyi's lawyer, Nyan Win, told reporters.
'We don't want to speculate, but we will keep exploring all legal avenues.'
Ms Suu Kyi, 64, is on trial for allowing American intruder John Yettaw to stay at her home in May, when she was under house arrest.
He had evaded security to swim across the Inya Lake to the house.
She faces five years in prison if convicted.
Ms Suu Kyi was awarded the title of 'Ambassador of Conscience' by rights group Amnesty International last night.
The announcement was made by Bono at U2's third Dublin concert at Croke Park.
