== Aim ==
 
* To provide a continuous check within Mailnews and its sub-components for the following items:
*# Total memory leaks.
*# Total memory usage (aka bloat).
* Provide a consistent number from build to build where no source code has changed.
* Provide reasonable coverage for the normal activities that a user performs.
 
== Method ==
 
Initial Method:
 
* Measure Leaks and Bloats, in a similar way to Firefox (using XPCOM_MEM_LEAK_LOG and --trace-malloc).
* The method of testing memory bloat and leaks will be the same sequence of events, using the same set of test data.
*# Startup Main Mail Window
*# Open Address Book Window, close Address Book Window
*# Open Message Compose Window, close Message Compose Window
*# Close Main Mail Window
 
To be added at a later stage:
 
* Large Message folders and selection thereof.
* Large Address Books.
* Sending/Receiving on different protocols (this would run best with local servers being setting up i.e. same physical hardware).
 
== Results ==
 
Printed via standard tinderbox methods, these will consist of:
 
* Mail RLk
** Reference Count Leaks
* Mail Lk
** Total Bytes malloc'ed and not free'd
* Mail MH
** Maximum Heap size
* Mail A
** Allocations - number of calls to malloc and friends.
 
== Code Locations ==
 
The existing [http://mxr.mozilla.org/seamonkey/source/tools/tinderbox/ tinderbox code] will be used to drive the tests, this may require migrating to [[Buildbot]] at an appropriate stage.
 
The files specific to mailnews testing will be stored in:
 
/mozilla/testing/mailnews/bloat/
 
These files consist of:
 
* An overlay (bloatTestOverlay.xul) which is used to overlay the main windows and loads bloatTestOverlay.js
* An script (bloatTestOverlay.js) which is used to drive the actual tests.
 
== Pre-defined profile ==
 
Initial Setup:
 
* One POP3 account (Mails TBD)
* One Identity
* One SMTP server defined (not used)
 
Future requirements/possibilities:
 
* One Address Book where PAB has ~1000 entries
* Large Message folders
* IMAP
* NNTP Server and subscribed newsgroup.
 
08/04/2008: prefs.js created via TB with the above settings, the first section is for preferences included in tinderbox, the second section is ones which don't currently get set.
