Status: RESOLVED FIXED

(Thunderbird :: Add-Ons: Extensions API, enhancement)

Description

[Geoff Lankow (:darktrojan) [away until 16/11]]

We're nearly ready to run mochitests on TaskCluster, so I've created some tests for the addressBooks, browserAction, and composeAction APIs.

it could be useful for these tests to have more descriptions of what they are doing, so people don't have to read the code that carefully ;)

why isn't this inside the function?

Why not Services.tm.dispatchToMainThread directly?

A few small updates. I made a patch of the pref changes needed to run this stuff locally, and put it here: https://gist.github.com/darktrojan/3474b57149635c322dd8b3e59cdfa89f.

Managed to get rid of a lot of flakiness. I think it still fails every now and then, but as far as I can tell, that's because of something dodgy in the WebExtensions framework.

might be better to use @example.com

Okay.

It's assigned in one function and used in another and I don't want to pass it around all over the place. What's the problem?

I see. Perhaps best to use the gAccount convention to make that clearer.
