You shouldn't expect any test to be reliable or repeatable or indicative of 
anything.  Because junk mail filtering is all about probability assignment, 
based on many complex and variable factors, using all the information available 
at the recipient system - including the IP address that sent the message, DNS 
associated to that IP address, what protocols were used, what version of mailer 
the sender is using, not to mention the contents of your message.

You might have passed the spam filter when you emailed yourself, just because 
you've been known to email yourself before - or because it forwards back to 
yourself.  These are known factors at the recipient machine, which may or may 
not affect the spam score it assigns.

The best thing to do is to simply follow *all* best practices, because every 
recipient system will behave differently.
