gnome-screenshot test needs drop-shadow feature added

[Carla Sella]

Autopilot test: http://bazaar.launchpad.net/~ubuntu-testcase/ubuntu-autopilot-tests/trunk/files/head:/ubuntu_autopilot_tests/screenshot/

Gnome-screenshot 'Apply effect' drop down box has these attributes:

        self.drop_shadow_effect_shadow=self.app.select_single('GtkComboBoxAccessible', accessible_name='shadow')
        self.drop_shadow_effect_none=self.app.select_single('GtkComboBoxAccessible', accessible_name='none')
        self.drop_shadow_effect_border=self.app.select_single('GtkComboBoxAccessible', accessible_name='border')

When trying to use these attributes for instance:

        #Select Drop shadow from the Apply effect drop down menu
        if self.drop_shadow_effect_none.enabled == 'True':
           self.pointing_device.move_to_object(self.drop_shadow_effect_none)
        elif self.drop_shadow_effect_shadow.enabled == 'True':
           self.pointing_device.move_to_object(self.drop_shadow_effect_shadow)
        else:
           self.pointing_device.move_to_object(self.drop_shadow_effect_border)
        self.pointing_device.click()
        self.keyboard.press_and_release('Down')
        self.keyboard.type('\n')
        self.pointing_device.click()
        self.pointing_device.click()

Autopilot returns this error:

Traceback (most recent call last):
  File "/home/letozaf/ubuntu-autopilot-tests/ubuntu_autopilot_tests/screenshot/test_screenshot.py", line 107, in test_drop_shadow_effect
    if self.drop_shadow_effect_none.enabled == 'True':
AttributeError: 'NoneType' object has no attribute 'enabled'

The attribute 'enabled' exists if you look for it with autopilot vis.

Hi,

If the object you are looking for exists within the vis tool, but appears not to exist in your autopilot test case, you should probably try using wait_select_single in autopilot 1.4, or something like this in 1.3:

self.assertThat(lambda: self.app.select_single('GtkComboBoxAccessible', accessible_name='none'), Eventually(NotEquals(None)))
self.drop_shadow_effect_none=self.app.select_single('GtkComboBoxAccessible', accessible_name='none')
