TestEngineering/UI/AMO/Tips and Pointers

Setup: staging and production

• Staging: https://preview.addons.mozilla.org
• Production: https://addons.mozilla.org

Production

Production push docs

• AMO uses Zeus, which heavily caches content. You can tell you're getting a cached copy of the content by looking at the headers and seeing "Via: Moz-Cache-zlb??" where ?? is a number and not seeing no-cache headers. being logged in bypasses this cache completely
• If you see some_string_define on AMO, it's either 1) a raw string define, or (more likely) 2) Apache needs to restart to pick up the gettext() changes.
• AMO runs on a cluster of servers. To tell what server is showing you the current page look for the "X-AMO-ServedBy" header.
• To view the revision of AMO you're currently seeing, view-source of any page; in the bottom, you'll see something like

  <!-- [http://viewvc.svn.mozilla.org/vc?revision=24322&view=revision r24322 -->

  This means you're at SVN revision number 24322 -- you can cross-link this to whatever revision number was posted in the checkin comment in the bug.

• Pages won't validate due to some proprietary attributes we use (like "addonname") but it should be very close.
• Database queries are cached in memcache for 60 minutes. This means if you change something that doesn't invalidate the cache it won't actually change for up to 60 minutes.
• If you want a really fast check to see if basic infrastructure is working look at the services monitor. This is also one of the things nagios watches.

Cron Jobs

• Personas are imported at :21 after the hour (both prod/preview)
• Calculating weekly download, total download, collections, and review stats happens every 20 minutes
• Calculating the compatibility report happens every 5 minutes
• You can see exact times and all cron jobs in http://github.com/jbalogh/zamboni/tree/master/scripts/crontab/

Testing

List of add-on types

• http://github.com/jbalogh/zamboni/blob/master/apps/amo/__init__.py#L98

Public vs. sandbox status

• If the latest version of a public add-on is in sandbox, then the previous public version of the add-on is listed in the add-on detail page.

Add-on Uploading

• Add-ons need to have:
  • At least 1 category
  • A description...

before they can be complete; click on the "Complete Add-on" button to make them so

• ...and now, they can be either in the "release" or "beta" channel

Status codes

• To be valid, an add-on must have:
  • Valid files
    • Which gives a version "valid" status

Special Add-ons

• EULA - Yahoo.com Toolbar
• Privacy Policy - Yahoo.com Toolbar

Buttons

AMO buttons

• Download the User Agent Switcher Add-on
• Open your firefox browser and type about:config
• Accept the terms and proceed
• Create a new boolean preference called useragentswitcher.reset.onclose with the value false
• Now add the user agents for Firefox Mobile, SeaMonkey and Thunderbird using the User Agent Switcher add-on
• Proceed to test the buttons

https://versioncheck.amo/

• Used by applications to see if their add-ons are up to date. Can be modified using about:config by changing

 extensions.update.url

• Should only output XML. Ever.

https://services.addons.mozilla.org/ (also known as the AMO API)

• Used for the API -- spec here, [https://developer.mozilla.org/index.php?title=en/addons.mozilla.org_%28AMO%29_API_Developers%27_Guide/The_generic_AMO_API DevMO doc here]
  • In Firefox's "Get Add-ons" tab (Tools->Add-ons->Get Add-ons). This can be configured using about:config by changing

 extensions.getAddons.recommended.url
 extensions.getAddons.search.url (replace "services" in each URL with "preview")

• SAMO filters by OS and version-compatibility ranges
  • e.g. If you're using Firefox 3.0.8 on Windows, you should only see add-ons that are either for "ALL" or "Win", with compat range of something -> 3.0.*
• You can test other locales in the API:
  • Lesezeichenleiste verstecken add-on
    • API search URL
  • For external sites, both 3rd party and sites like addons.mozilla.jp
  • Should only output XML. Evar.
• IMPORTANT: Gets tagged and shipped with AMO, usually, so be sure its changes have been vetted
  • Ask if it's been tagged along with the rest of the AMO changes, with each release

Staging

Found at: https://preview.addons.mozilla.org/

• The site updates from SVN every 15 minutes automatically. It also reruns the clean and build scripts which make the compressed js files, etc.
• The database is a very old copy from production AMO. It is only updated when requested through IT (talk to webdev first please).
  • -207 and -261 errors might sometimes abound; tread carefully. Usually, it's a staging-only file-mirror thing, but ya never know :-)
• If you're feeling wild you can directly access the staging database to verify table structure or data.

Errors to ignore:

• -261/-203 errors when trying to install an add-on *only* from https://preview.addons.mozilla.org -- the files aren't synced regularly from the file-mirror DB; if you see this on production, it's a bug and should be filed against IT (but wait half a day or so)

Featured add-ons

• Rotated/added/deleted through the Admin tool->Feature Manager -- have expiration dates

Discovery Pane

• Can be administrated through https://addons.allizom.org/en-US/firefox/discovery/modules

Testing Search (weights/ordering)

https://wiki.mozilla.org/Update:Remora:Search

Browse Page Vs. Category Landing Page

• Category Landing Page
  • when you click on a Category link from left navigation, you are generally taken to Category landing page (if there are a enough add-ons in that category
  • For e.g. if you are on 'Firefox' app page and you click on 'Shopping' category you will most likely land on Category Landing Page since this category has more than 5 add-ons
  • On Category Landing Page you should see a big section of category-featured add-ons on the top, on the bottom you should see 3 columns listing 'Recently Added', 'Top Downloads' & 'Top Rated' add-ons( all for that category). On the bottom of each column there is a link to 'View All' (in that category)
• Browse Page
  • when you click on a Category link from left navigation and if you end up on Browse page that's because there are not enough add-ons in that category to show a Cat. landing Page
  • For e.g. if you are on 'Mobile' app page and you click on 'Shopping' category you will most likely land on Category Browse page since this category fewer add-ons
  • Browse page will not have the 3 columns of 'Recently Added', 'Top Downloads' & 'Top Rated' add-ons.
