[shaansubbaiah.cs18 at bmsce.ac.in]

Hello all,
This took quite a while, long post ahead. Testing the Fructose activities:

| Chat | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
| Image Viewer | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |

| Write | ✓ | ✓ | ✓ | ✕ #40, Reported by Saumya | ✓ | 1. TTS ends halfway through the last word. 
 2. Default font differs for guest in collaboration #43 |


Terminal

Browse
All tests apart from the start/stop were done after installing libglib2.0-dev package which prevented the activity from opening.
   
   - Typing something in the search bar and clicking the search button or hitting Enter doesn’t do anything; whereas searching through the address bar works.
   - Typing in the address bar causes several (possibly 100’s) of warnings in the activity log   (sugar-activity3:7184): Gtk-WARNING **: 16:25:08.511: Failed to set text from markup due to error parsing mar
kup: Error on line 2: Entity did not end with a semicolon; most likely you used an ampersand character withou
t intending to start an entity — escape ampersand as &


Jukebox
   
   - Moving the OpenGL renderer window around creates a Windows XP-like Solitare effect 
   - Closing the OpenGL renderer window throws an error in the Jukebox log   1592561580.133608 ERROR root: ERROR MESSAGE: gst-resource-error-quark: Quit requested (3)
1592561580.133807 ERROR root: ERROR DETAIL: gstglimagesink.c(1781): gst_glimage_sink_show_frame (): /GstPipel
ine:pipeline0/GstPlayBin:playbin0/GstPlaySink:playsink/GstBin:vbin/GstAutoVideoSink:videosink/GstGLImageSinkB
in:videosink-actual-sink-glimage/GstGLImageSink:sink

   - Seeking ahead or back causes the OpenGL visualization to freeze, takes quite some time to recover, or doesn’t recover at all.
   -    
Clicking the full-screen button causes another OpenGL visualization of the same size to spawn on the left of the previous visualization, which is now frozen.

   -    
Sometimes while closing and playing songs in the playlist a huge amount of warnings appear in the jukebox log, not sure how to reproduce properly.

1592562307.413873 ERROR root: ERROR MESSAGE: gst-resource-error-quark: Quit requested (3)

Also, in ~/.sugar/default/data I noticed there were ~60 copies of the same song I had been playing. I had downloaded the song only once, perhaps it is something to do with how Jukebox handles the songs. This consumes a ton of space, in my case 7mb*60.

Read
Sometimes the last 2 characters in a txt file aren’t seen.
Reproduced by: Create a txt file in Write Activity -> Open with Read Activity -> Last 2 characters are missing.
This happens occasionally, the data in the txt file is intact.

Calculate
Typing random text instead of digits/variables throws an error. Should be handled.
1592573782.228379 DEBUG Calculate: Result: RuntimeError("Variable 'oklol' not defined", 0,
 5)

TypeError: 'NoneType' object is not subscriptable

Browse
Traceback in Host’s Browse log when Guest connects. The webpage opened in the host does not open in the Guest.
1592574235.567373 DEBUG CollabWrapper: __state_changed_cb dbus.UInt32(3) dbus.UInt32(0)

    return Gio.MemoryInputStream.new_from_data(self._blob, None)
TypeError: Item 0: Must be number, not str

Note, the tests:
   
   - Don’t include issues that were already tracked in Github.
   - Cover almost all the functions of an activity.
   - Save/Restore refers to closing and reopening the activity and checking if there are any changes for activities that do not have an explicit save functionality.
   - Includes most, if not all errors that were logged while testing the activities. Ideally nothing should be left out, but …
   - Will be covered in more detail if possible for Debian unstable and testing, this was to set up a baseline.
I still have to decide on a plan to test Sugar’s features (non-activity-related).Please let me know if I have missed anything. Let me know if you face these issues as well, would be very helpful in determining if they are due to Debian or Sugar.

Best,Shaan
