Notes on Battery Testing

When building from source, an executable 'indicator-power-service-cmdline-battery' will be built in the tests/ directory. This has the same code as indicator-power-service, except instead of listening to UPower it has a single fake battery that can be set from the command line to set its charge level and whether it's charging or discharging.

You'll need to stop the current indicator-power-service before starting the test one. After that, you enter in a number, or 'charging', or 'discharging', to set the fake battery. ctrl-c exits.

Example:

$ stop indicator-power # stop the real indicator-power service
$ build/tests/indicator-power-service-cmdline-battery # start the test service
50 # sets the fake battery level to 50%
30 # sets the fake battery level to 30%
charging # sets the fake battery to charging
discharging # sets the fake battery to discharging
ctrl-c # exits the test service
$ start indicator-power # restart the real service

    <dt>Start a system and wait for the greeter or logout of the current user session</dt>
    <dt>Go to the panel and click on the Power indicator</dt>
        <dd>Ensure there are items in the menu</dd>
</dl>

Test-case indicator-power/unity8-items-check
<dl>
    <dt>Login to a user session running Unity 8</dt>
    <dt>Pull down the top panel until it sticks open</dt>
    <dt>Navigate through the tabs until "Battery" is shown</dt>
        <dd>Battery is at the top of the menu</dd>
        <dd>The menu is populated with items</dd>
</dl>

Test-case indicator-power/detect-charging-or-discharging
<dl>
    <dt>Begin with a discharging device</dt>
        <dd>The indicator's icon should denote a discharging battery; e.g. an icon without the '⚡' sign</dd>
    <dt>Plug it in so that its battery is charging</dt>
        <dd>The indicator's icon should change to show a charging battery</dd> 
    <dt>Unplug it again</dt>
        <dd>The indicator's icon should revert back to the same one in step one</dd>
</dl>

Test-case indicator-power/low-power-notifications
<dl>
    <dt>Wait for the system's battery level to drop to 10% (or fake it, see 'Notes on Battery Testing' above)</dt>
        <dd>A notification should appear</dd>
        <dd>Its title should read "Battery Low"</dd>
        <dd>Its text should read "10% charge remaining"</dd>
        <dd>The icon should be a low power icon</dd>
        <dd>It should have two actions, "Battery settings" and "OK". </dd>
    <dt>Tap OK to dismiss the popup</dt>
    <dt>Wait (or fake) the battery level to drop to 9%</dt>
        <dd>No new notification should appear -- we're still at the "Low" level </dd>
    <dt>Wait (or fake) the battery level to drop to 4%</dt>
        <dd>A notification should appear</dd>
        <dd>Its title should read "Battery Critical"</dd>
        <dd>Its text should read "4% charge remaining"</dd>
        <dd>The icon should be a critical power icon</dd>
        <dd>It should have two actions, "Battery settings" and "OK". </dd>
    <dt>Tap 'Battery Settings'</dt>
        <dd>ubuntu-system-settings should be launched to the Battery page </dd>
</dl>

Test-case indicator-power/device-brightness-slider
<dl>
    <dt>On a device, pull down the power indicator's menu</dt>
        <dd>The menu should include a brightness slider with icons</dd>
    <dt>Slide the brightness slider back and forth</dt>
        <dd>The screen should get brighter and darker in sync with the slider's position</dd>
    <dt>Launch unity-system-settings' Brightness panel</dt>
    <dt>Move both the indicator's and the settings panel's sliders</dt>
        <dd>Both sliders' positions should stay in sync with each other</dd>
        <dd>Both should have the same effect on the screen's brightness</dd>
    <dt>Make a note of the current brightness level and slider position</dt>
    <dt>Reboot the device</dt>
        <dd>The screen brightness should be the same as it was before rebooting</dd>
        <dd>The indicator's brightness slider should be in the same position as it was before rebooting</dd>
