XS Tests

From:
http://spreadsheets.google.com/pub?key=pJrekGFLbqe6sdOitu3tYbQ

0 - Basic connectivity check
Definition: ISP --- HUB --- XF --- XS --- XO
PC or XO ---> (SSH) --> XF (opens terminal on headless XF machine)
PC or XO --> (SSH) --> XF --> (SSH) --> XS (opens SSH terminal window on headless XS machine)
XF --> (eLinks HTTP) --> XS (this is my main page for XS school server)
XS ---> (eLinks HTTP) <-- XF (this is just the dummy Fedora/Apache test page running on XF) XO channel 1 mess ---> (Browse) --> XS (click "Schoolserver" on Google start page to see XS home)

Status:
Notes:

1 - Apply image to XO from USB
Status (include date tested): pass
Notes: Can be done through firmware with copy-nand command
Question: Was this test done with developer key?

2 - Connects to Mesh
Status (include date tested): pass
Notes:

3 - Can browse Internet
Status (include date tested): pass
Notes:

4 - Can browse cached pages
Status (include date tested): pass
Notes:

5 - Can browse cached pages when Internet offline
Status (include date tested):
Notes:

6 - Chat w/ other XO
Status (include date tested): pass
Notes:
Question: "Chat with Other XO" -- Ok, to test chat before, I used my Thinkpad T60 running QEMU using the website "xochat.org" to connect with my XO laptop. If we have ejabberd running on the XS, would I connect my laptop and XO to "ejabberd" and have the XO over the mesh, and the Thinkpad over the Wi-Fi? If not, I will need to borrow my friend's XO for a pure mesh-to-mesh test.


7 - Can access Moodle page and click on all links
Status (include date tested):
Notes:

8 - Load new activities from server
Status (include date tested):
Notes:

9 - Can launch Squeak activity from Moodle
Status (include date tested):
Notes:
Question: is this the same as eToys, or did you mean the developers version of Squeak on the OLPC website?

10 - Browse Wiktionary
Status (include date tested):
Notes:

11 - Play audio from Wiktionary
Status (include date tested):
Notes:

12 - Play flash videos
Status (include date tested):
Notes:

13 - Fill up XO’s hard drive
Status (include date tested): Fail Notes: When the drive fills up, the app crashes and you are not able to open another app until you free some space

14 - Remove activities manually
Status (include date tested):
Notes:
what does this mean. I have been able to add activities to my XO by downloading the XO files to my Journal and installing them, but the only way I have been able to remove them was dropping down into "Terminal" activity and hacking away at the file trees with "rm" commands. Is there a better way to test this?

15 - Automatic Backup and manual restore
Status (include date tested):
Notes:

16 - Attempt restore student files over the network
Status (include date tested):
Notes:

17 - XO can access School server via another XO through mesh, record distance and signal/packet loss
Status (include date tested):
Notes:

18 - Try to access www.hotsex.com
Status (include date tested):
Notes:

19 - Access ds.lahai.com/ole/fez
Status (include date tested):
Notes:

20 - Type in Nepali, save text in Nepali
Status (include date tested): Fail 2/12 reported 2/14 by TP
Notes: Is there an image I need to install on my XO to be able to read both English and Nepali script?

21 - Sugar appears in Nepali
Status (include date tested): partial
Notes: The translation is done at http://dev.laptop.org/translate

22 - Hard reboot test
Description: Pull the power cord on XS while XO is browsing. Plug it back in and see run connectivity test 0 above to show everything comes back without intervention.
Status:
Notes:

23 - New Test Idea We should also develop some tools that generate activity, this would help identify memory leaks and what logs needs to be tailed over time.
