I have added somes marionette tests for data connection.
However, when I tested locally, I do get "ScriptTimeoutException: timed out" sometimes (like 2 out of 10 times), and the reason is:

I/Gecko   (   45): MARIONETTE TEST RESULT:TEST-PASS | test_data_call.js | set 'ril.data.enabled' to true - true was true, expected true
I/Gecko   (   45): -*- RadioInterface[0]: 'ril.data.enabled' is now true
I/Gecko   (   45): -*- RadioInterface[0]: We haven't gotten completely the APN data.

I haven't found out why we didn't get "ril.data.apnSettings" correctly, but should we set "ril.data.apnSettings" manually (I mean in test_data_call.js) before the test to make sure it runs properly?

Comment 2

[Vicamo Yang [:vicamo][:vyang]]

I think not.  I can find following line in Marionette log:

  I/Gecko   (   45): -*- RadioInterface[0]: 'ril.data.apnSettings' is now [[{"carrier":"T-Mobile US",
  "apn":"epc.tmobile.com","mmsc":"http://mms.msg.eng.t-mobile.com/mms/wapenc",
  "types":["default","supl","mms"]}]]

Yes, it only happens randomly. As discussed, I will try to test and see if it's a race condition or not.

This patch is causing a strange error in the try server: https://tbpl.mozilla.org/?tree=Try&rev=c56762b37032
So I will need to check it again, thank you.

The APN issue didn't look like a race condition, I let the test waited for 5 mins and still empty ril.data.apnSettings.
In this patch, I set the ril.data.apnSettings before the test and it works fine...

This one passes on try server:

Besides the comments below, I'd really like to sale task based test script layout[1].  It helps for distinguishing test cases from utility functions and gives you a clear trace of the progress.

You can just have |SpecialPowers.setBoolPref(key, value)| and call |SpecialPowers.clearUserPref(key)| at the end.

Please have a utility function for this.  See test_filter_mixed.js[1].  Or this case may, not very often, result in an intermittent failure like bug 903058.

Actually, you don't have to squeeze everything into a |verifyInitialState| function.

Could you make two utility functions, one for setting Settings and another for retrieving?

Please define |setEmualtorAPN| or other utility functions before calling them.

listen to on{voice,data}statechanged instead.

ditto.  We can't verify network state by transmitting an packet out, so the two state changed events are the only things we can ensure.

Please define setEmulatorRoaming earlier.

Good job! Finally! We have test cases for data connections! r=me with some nits addressed.

Thank you!
This patch addresses nits in Comment 7:

- use braces even with one-line statement
- call tasks.finish() instead of cleanUp() directly
- add connection listener before action
- keep warning line before last task

Remove bug 821578 from prerequisite list, test cases here don't touch the different APN names issue.
