'runScript' is not defined

Hi,

I am using SikulixIDE 1.1.0 which really a good tool ;) but when trying to launch several scripts I cannot use the function "runScript".

I Have 2 scripts (MainScript and LoginFromExactUserName) :

#MainScript

from sikuli.Sikuli import *
from sikuli import *
import unittest

class MyTest(unittest.TestCase):
    def testBatch(self):
        Settings.MyUserName = "Administrator"
        currentResult = runScript("Y:/Scripts/LoginFromExactUserName")
        self.assertEqual(currentResult,1)
        Settings.MyUserName = "Super manager"
        currentResult = runScript("Y:/Scripts/LoginFromExactUserName")
        self.assertEqual(currentResult,1)

suite = unittest.TestLoader().loadTestsFromTestCase(WynsureUS54Test)
unittest.TextTestRunner(verbosity=2).run(suite)

#LoginFromExactUserName

from sikuli.Sikuli import *
from sikuli import *

UserName = Settings.MyUserName

print UserName
===============================================

Here is the log I get when running from IDE "MainScript":
testBatch (__main__.WynsureUS54Test) ... ERROR

===============================================
ERROR: testBatch (__main__.WynsureUS54Test)

Any idea of why this runScript function is not defined, I missed some declaration ?
Thank you for your help.
