• How can I prevent javascript errors in my selenium tests from hanging my build system?

  - by lowellk

  We are having a problem with our selenium tests which run in IE on a virtual machine. Whenever there is a javascript error, a popup shows up and puts our system into a 'stuck' state - a user has to go clear that and restart the selenium test run. Is there a way to prevent the javascript error popup from putting the system into its stuck state? Would setting window.error be of any help here?

• Can I update an Android provider.Settings.System value?

  - by Mr_Ed

  I can read settings like this, for example: final String mytest = System.getString(this.getContentResolver(), System.AIRPLANE_MODE_ON); ...but can't seem to write to settings using putString, no matter what I've tried. Maybe it is the scope of this.getContentResolver()??? I'm a newbie, so who knows, maybe it can't be done, or it's just syntax? Currently the code is in the onCreate of an Activity class. Any insight is much appreciated.

• Is it alright to call len() in a loop's conditional statement?

  - by DormoTheNord

  In C, it is considered bad practice to call strlen like this: for ( i = 0; strlen ( str ) != foo; i++ ) { // stuff } The reason, of course, is that it is inefficient since it "counts" the characters in a string multiple times. However, in Python, I see code like this quite often: for i in range ( 0, len ( list ) ): # stuff Is this bad practice? Should I store the result of len() in a variable and use that?
