- This feature enables developers to view an extension’s storage local data in the addon toolbox storage panel.
- The goal of this issue is creating a new Storage actor, Extension Storage, to be able to inspect and manipulate data stored by an addon in the WebExtension storage APIs and to ensure that it is only activated when the debugging target is a WebExtension.
When the devtools.storage.extensionStorage.enabled config is set to True and the developer toolbox is targeting an extension process, the Extension Storage actor should be listed in in the Storage panel.
This document purports to detail the test approach for the adding a new Storage actor and includes Entry/Exit criteria, Scope for testing, links to test cases etc
- QA has access to all the PRDs, mocks and related documents
- The feature has landed on Beta
- Kick off meeting has been finalized
- All the bugs against the feature have been triaged
- All the P1/P2 bugs have been fixed
- All the resolved bugs have been verified by QA
- The find/fixed rate is going down over a predefined period of time
This section broadly outlines when the product is ready to ship
- QA has signed off
- All info is localized at least for a pre-defined set of locales
- All the necessary PR/blogposts have been sent out
This section describes what parts of the feature will be tested and what parts won't be.
what's in scope?
- The accuracy of the data displayed in the table any time data is modified in any way.
- That the “Extension Storage” list item shows up as expected in the left sidebar in the right situations and doesn’t show up in the wrong situations.
- That any extension that makes use of extension storage local can be inspected using this feature.
- Note that only JSONifiable values are displayed as-is in the patch; all other values are displayed as “Object”.
what's out of scope?
- Issues with the Storage panel UI itself outside of the data in the table for a particular extension under “Extension Storage”.
- How the toolbox changes or not if left open when an extension is installed/uninstalled/disabled/enabled.
- Issues with the WebExtensions APIs.
Requirements for testing
The Storage panel should reflect the current state of extension storage local at all times for any kind of web extension.
OSes covered: Windows, Mac OS X, Linux
Channel dependent settings (configs) and environment setups
- Enable devtools.storage.extensionStorage.enabled from about:config
- Enable devtools.storage.extensionStorage.enabled from about:config
The feature should be enabled by default in FF70
This section details the progression test objectives that will be covered. Please note that this is at a high level. For large projects, a suite of test cases would be created which would reference directly back to this master. This could be documented in bullet form or in a table similar to the one below.
