Bug description:
This crash is created by using the following ldtp script.
#!/usr/bin/env python
import os
import sys
import unittest
import ldtp
import time
start_time = time.time()
class ss_of_USC(unittest.TestCase):
def setUp(self):
ldtp.launchapp('software-center')
assert ldtp.waittillguiexist('frmUbuntuSoftwareCentre')
self.msgs = []
a = "Time taken for the frame to open is " + str(time.time() -
start_time)
self.msgs.append(a)
def tearDown(self):
ldtp.selectmenuitem('frmUbuntuSoftwareCentre', 'mnuClose')
assert ldtp.waittillguinotexist('frmUbuntuSoftwareCentre')
c = "This test took a total of " + str(time.time() - start_time)
self.msgs.append(c)
print '\n'.join(self.msgs)
def test_1(self):
ldtp.waittillguiexist('frmUbuntuSoftwareCentre', 'btnAccessories')
assert ldtp.objectexist('frmUbuntuSoftwareCentre', 'btnAccessories')
b = "Time taken from start to find the Accessories button " +
str(time.time() - start_time)
self.msgs.append(b)
if __name__ == "__main__":
unittest.main()
This crash is very reproducible with this script, which just times how
long certain parts of USC take to load.
