======
- Test Plan: Android Power/Battery-Use (Google Doc, WIP)
- Main bug: bug 1511350 - Test impact of dark mode on power usage
Preliminary Setup:
- Your Moto G5 (unlock, specs) and/or Pixel 2 unlockspecs phones should be rooted and OEM/carrier-unlocked (further unlocking docs
- Python 3.7.3 is installed and available in your system
$PATH - You have git installed and configured, also available in your system
$PATH - adb is installed and available in your system
$PATH(ifadb devicesdoesn't spit out errors, you should be good to go) git cloneyour fork of https://github.com/mozilla/powerusage-android (read-only would be:git clone https://github.com/mozilla/powerusage-android)cd powerusage-androidpython3 setup.py develop:

Test-Environment (Device) Cleanup
Uninstall Browser Apps
Manually: tap and hold until you can drag to the Uninstall option at the top right) all of your current Firefox-based browser apps (Fennec, GeckoView Example [GVE], Fenix, and Reference Browser [RefBrow]).
Install Browser APKs:
I will prettify this later, but here are my (Stephen) build sources, for my Moto G5, running Android 7.x:
- Fennec (Firefox 64.0.2): https://archive.mozilla.org/pub/mobile/releases/64.0.2/android-api-16/en-US/fennec-64.0.2.en-US.android-arm.apk
- RefBrow: https://index.taskcluster.net/v1/task/project.mobile.reference-browser.signed-nightly.nightly.2019.4.9.latest/artifacts/public/target.arm.apk
- Fenix: https://index.taskcluster.net/v1/task/project.mobile.fenix.signed-nightly.nightly.2019.4.9.latest/artifacts/public/target.arm.apk
- GVE: https://taskcluster-artifacts.net/dzV5pl0SRz6IvbIDR1TEIA/0/public/build/geckoview_example.apk
(Greg can add his here too if so desired)
Running a Test:
- For each color's power test, you must
mkdir [unique name]with a convention of your choosing;black-bg,white-bg, etc. - From the top-level (root) dir, run (e.g. substituting values, where appropriate):
$ ./scripts/blackbg-test.sh --output black-bgEnsure that your custom dir exists prior to the above test run;resultsor similar, will do, for our purposes. - You should now see output similar to https://gist.github.com/stephendonner/9c611a3dfc6d26c4f203bd06b38f688b:
Here's a sample "batch" test of colors, called eye_of_sauron.py:
#!/bin/bash
scripts/blackbg-test.sh black-bg fennec-64.0.2.en-US.android-arm.apk refbrow-target.arm.apk target.arm.apk geckoview_example.apk
scripts/whitebg-test.sh white-bg fennec-64.0.2.en-US.android-arm.apk refbrow-target.arm.apk target.arm.apk geckoview_example.apk
scripts/redbg-test.sh red-bg fennec-64.0.2.en-US.android-arm.apk refbrow-target.arm.apk target.arm.apk geckoview_example.apk
scripts/greenbg-test.sh green-bg fennec-64.0.2.en-US.android-arm.apk refbrow-target.arm.apk target.arm.apk geckoview_example.apk
scripts/bluebg-test.sh blue-bg fennec-64.0.2.en-US.android-arm.apk refbrow-target.arm.apk target.arm.apk geckoview_example.apk
Note: at the time of this doc update, greenbg-test.sh and bluebg-test.sh are not in-tree, and are used to test locally and here for illustrative purposes.
We'll soon be moving to Raptor proper, to hook into All the Things™ we need for capabilities of all types.
Running Android Pre/Post test. Running white background color test.
Make sure you have no extra apps running in the background. Make sure that there is a wakelock app running(if going passed 30 minutes of testing). Charging is disabled before the test starts. It is enabled automatically when we reach the end of the test. Getting Phone Model... Is the model Moto_G__5 correct? Disabling charging... Old screen timeout: 12000000

followed by the magic and substance of the test/measurements, which are the (many) datapoints, of which we are currently focused on Charge-Counter values (Charge counter: 267234), as well as deltas, variance across scenarios, etc:
