| 282 <p>The default update check frequency is several hours, which obviously makes te
sting challenging. To overcome this, you can use the --extensions-update-frequen
cy command line flag to set a more frequent interval in seconds. For instance, t
o make checks run every 45 seconds, you would run chrome like this:</p> | 340 <p>The default update check frequency is several hours, |
| 341 but you can force an update using the Extensions page's |
| 342 <b>Update extensions now</b> button. |

| 344 |
| 345 <p> |
| 346 Another option is to use the --extensions-update-frequency command-line flag to
set a more frequent interval in seconds. For instance, to make checks run every
45 seconds, you would run Google Chrome like this:</p> |

| 285 <p>Note that this affects checks for all installed extensions, so consider the b
andwidth and server load implications of this. You may want to temporarily unins
tall all but the one extension you are testing with, and should not run with thi
s option turned on during normal browser usage. In the future we may remove this
command flag and replace it with a different mechanism to trigger update checks
for testing (perhaps a button on the chrome://extensions page). Star the follow
ing issue to receive updates: <a href="http://crbug.com/17853" rel="nofollow">ht

| 319 <p>As we add more API's to the extensions system, it's possible you will want to
release an updated version of an extension that will only work with newer versi

days before the majority of the userbase has updated to any given new release.
To ensure that a given extension update will only apply to chrome version at or
higher than a specific version, you would add the prodversionmin parameter to th
