It depends on how close you want those mirrors to be. If they are 
absolutely identical:

 ln -s ../testB /home/user/testA

will create a symbolic link between the two directories. You can 'cd' 
into either testA or testB and see identical files, changes happen 
immediately etc. A symbolic link essentially allows you to give a 
directory a second name.

If this is for backup purposes and you want to periodically bring testB 
up-to-date with testA, then rsync is your best choice:

 rsync -avP --delete /home/user/testA /home/user/testB

This is a one-way synchronisation. testB becomes identical to testA, and 
any changes in testB are lost. If you need two-way synchronisation 
(testA and testB have changed, but need to come to a common state), then 
look at the "unison" package.
