Software Update:HowToTestMajorUpdateUI

Here's the quick and dirty way to test Major Update UI, specifically the detailsURL attribute and the licenseURL attributes (specified at Software_Update:updates.xml_Format).

create a "fake" updates.xml file on your local machine

A "fake" updates.xml file looks like this:

<?xml version="1.0"?>
<updates>
  <update type="major" version="3.0" extensionVersion="3.0" buildID="2006030713" licenseURL="http://www.mozilla.com/test/sample-eula.html" detailsURL="http://www.mozilla.com/test/sample-details.html">
    <patch type="complete" URL="https://bugzilla.mozilla.org/attachment.cgi?id=242833" hashFunction="SHA1" hashValue="a3ab33bc0dcabd86050013826da8e3a11ab691b2" size="54"/>
  </update>
</updates>

note, https://bugzilla.mozilla.org/attachment.cgi?id=242833 is a special, 54 byte, empty mar that does nothing to your build if you install it. So use this when testing the UI.

note: your licenseURL and detailsURL need to be on a website, and can not be file:// urls.

configure your prefs to point at the "fake" update.xml file

use about:config and set the app.update.url.override pref to your file, for example file:///C:/Documents%20and%20Settings/mozilla/Desktop/update.xml

check for updates

Use "Help | Check for Updates..." and you should get the Major Update UI for this "fake" update that you created.
