The test should clearly describe 3 stages:
The test should clearly describe 3 stages:
; Preparations
;Preparations
: These are actions that test does before the process(es) get checkpointed

;Checks

: After restore test should verify whether everything is OK or not
: After restore test should verify whether everything is OK or not and report the result
This is achieved by using the following API calls:
This is achieved by using the following API calls:
;<code>test_init()</code>
;<code>test_init(argc, argv)</code>
:Just initializes the test subsystem.
:Just initializes the test subsystem. After this call the preparations stage starts.

:This one says that we finished preparations and ready to get dumped at any time. I.e. -- the ''actions'' begin.
;<code>test_go()</code>
:This routine checks whether the process was dumped and restored or not yet, i.e. the ''actions'' stage still goes on.
;<code>test_waitsig()</code>
;<code>test_waitsig()</code>
:Calling this blocks the task till it's restored. After this the ''checks'' stage starts.

;<code>pass()</code>
:Calling this marks test as PASSED
;<code>fail(message)</code>
:Calling this would report test failure. The ''message'' argument will be written into logs
;<code>err(message)</code>
:Use this function to mark the test as being unable to work at all.
;<code>test_msg(message)</code>
:This is for logging.
From the code perspective this looks like this:
