How to run unit test in IDE

need more information about your problem.

send me your zipped .sikuli to my mail: https://launchpad.net/~raimund-hocke

i only try execute one

assertExists(PATH_IMAGE)

and not work me, really i don't know how use this windows (unit test)

Only to be clear:

You always need a basic structure like that:

--1. Enter this in IDE:

def setUp(self):
 # here goes your code to prepare
 print "in Setup"

def tearDown(self):
 # here goes your code to sum something up
 # after all tests have been run
 print "in tearDown"

def test_empty(self):
 # each test case needs it's own def()
 # named test....
 print "in test"
 return True

instead of the True in return True you might use any expression that evaluates to True (test passed) or False (not passed):
e.g. your
assertExists(PATH_IMAGE)

Tip: it is recommended to only use the standard assert statements, so yours should read:
assert(exists(PATH_IMAGE))

--2. save the script e.g. test.sikuli (the script has to be saved after each change of your script before the next testrun)
then go to the testrun window and press run.

thank you very much, the problem is:

the "run" button not appear always :S
sometimes not appear.

Thank you =)

if the run button is not visible, a test is still running in background.

Currently, you have to kill and restart Sikuli-IDE (bug reported) in cases where it does not end by itself.
