Excel Add-In Release/Test Procedure
 

Can someone recommend a release/test procedure for Excel Add-ins? It
seems that keeping add-ins-to-test in a testing directory and
add-ins-in-production in some production directory doesn't work because
I can't flip between the add-in in test and production. Changing the
location of the add-in using Excel's add-in menu works about 20% of the
time so I can't reliably figure out if I am using an add-in from the
test or production directory. Any suggestions?
