Hi,

1. How-To article of the month and notable things!
-> In the Sheriff Newsletter we mentioned the “Orange Factor” but what is this ?  It is simply the ratio of oranges (test failures) to test runs. The ideal value is, of course, zero.

Practically, this is virtually impossible for a code base of any substantial size,so it is a matter of policy as to what is an acceptable orange factor.

It is worth noting that the overall orange factor indicates nothing about the severity of the oranges. [4]

The main site where you can checkout the “Orange Factor” is at https://brasstacks.mozilla.com/orangefactor/  and some interesting info’s are here https://wiki.mozilla.org/Auto-tools/Projects/OrangeFactor
-> As you might be aware Firefox OS has moved into Tier 3 Support [5] – this means that there is no Sheriff Support anymore for the b2g-inbound tree.

Also with moving into tier-3 – b2g tests have also moved to tier 3 and this tests are by default “hidden” on treeherder. To view test results as example on treeherder for mozilla-central you need to click on the checkbox in the treeview “show/hide excluded jobs”.

2. Get involved!
