Ubuntu Wiki

Below are the test cases that should be run when gnome-settings-daemon is updated to new major releases in the development version of Ubuntu. These should also be run for all gnome-settings-daemon Stable Release Updates.

The GNOME Settings Daemon is responsible for setting various parameters of a GNOME Session and the applications that run under it.

All tests are meant to be executed from a GNOME Wayland desktop session (the default Ubuntu Desktop session).

Test A11y

1. Enable the Screen Reader
2. Verify that the AT-SPI bus was enabled:

   gdbus call --session -d org.a11y.Bus -o /org/a11y/bus -m org.freedesktop.DBus.Properties.Get org.a11y.Status IsEnabled

Test Color

1. Open gnome-control-center (Settings app)
2. Enable Night Light
3. Configure start and end times so that it should enable now
4. Verify that Night Light is active:

   gdbus call --session -d org.gnome.SettingsDaemon.Color -o /org/gnome/SettingsDaemon/Color -m org.freedesktop.DBus.Properties.Get org.gnome.SettingsDaemon.Color NightLightActive

Whether the screen actually changed color depends on other components; in case it did not, that should not count as a failure of this test case.

Test Housekeeping - Thumbnails

1. Set the thumbnails cache age to zero:

   gsettings set org.gnome.desktop.thumbnail-cache maximum-age 0

2. Log-out and log-in (or reboot and log-in)
3. Wait at least 2 minutes
4. Verify that the thumbnails cache is empty:

   find ~/.cache/thumbnails -type f

5. Restore the default cache age

   gsettings reset org.gnome.desktop.thumbnail-cache maximum-age

Test Housekeeping - Trash

1. Move some files to the trash bin
2. Run:

   gdbus call --session -d org.gnome.SettingsDaemon.Housekeeping -o /org/gnome/SettingsDaemon/Housekeeping -m org.gnome.SettingsDaemon.Housekeeping.EmptyTrash

3. Verify that the trash bin is empty

Test Media Keys

This test requires a keyboard with media control keys

1. Verify that the Volume Up/Down and Mute keys modify the volume

2. Start a media player, for example YouTube within Firefox

3. Verify that the Play/Pause/Next/etc... keys work as expected.

Test Power - Idle Suspend

This test requires a machine with suspend support.

1. Enable Automatic Suspend
2. Configure a low sleep timeout for the test:

   gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 30

3. Wait 30 seconds
4. Verify that you saw a notification: "Suspending soon because of inactivity."
5. Verify that the machine went to sleep
6. Reset the default sleep timeout

   gsettings reset org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout

Test Power - Lid

This test requires a laptop with a sensor detecting when the lid is closed.

1. Inhibit suspend:

   systemd-inhibit --what=handle-lid-switch gnome-session-inhibit --inhibit suspend sleep 60

2. Close the laptop lid
3. Verify that the session was locked.

Test Power - Backlight

This test requires a laptop with supported screen backlight controls.

1. Open the Quick Settings menu at the top-right of GNOME
2. Verify that there is a brightness slider
3. Verify that moving the slider adjusts the screen brightness

Teset Rfkill

1. Open the Quick Settings menu at the top-right of GNOME
2. Enable Airplane Mode
3. Verify that Wifi and Bluetooth got turned off

Test ScreensaverProxy

1. Run:

   gdbus call --session -d org.freedesktop.ScreenSaver -o /org/freedesktop/ScreenSaver -m org.freedesktop.ScreenSaver.Inhibit "foo" "bar"

2. Verify that the command returned a number The session will be automatically uninhibited as soon as the gdbus command exits.

Test Sharing

• This test requires that the rygel package is installed

• Connect to a secure network
• Run:

  gdbus call --session -d org.gnome.SettingsDaemon.Sharing -o /org/gnome/SettingsDaemon/Sharing -m org.freedesktop.DBus.Properties.Get org.gnome.SettingsDaemon.Sharing CurrentNetwork

• Verify that the command returned a non-empty identifier
• Run:

  gdbus call --session -d org.gnome.SettingsDaemon.Sharing -o /org/gnome/SettingsDaemon/Sharing -m org.freedesktop.DBus.Properties.Get org.gnome.SettingsDaemon.Sharing SharingStatus

• Verify that the command returned the number "3", meaning "sharing is available"
• Disconnect from the network
• Verify that the same command now returns "0"

Smartcard

This test would require a smartcard and a system configured for log-in with the smartcard. Instead, we're just going to verify that the service is running and can perform a basic query.

1. Log-in without a smartcard.
2. Run:

   gdbus call --session -d org.gnome.SettingsDaemon.Smartcard -o /org/gnome/SettingsDaemon/Smartcard/Manager -m org.gnome.SettingsDaemon.Smartcard.Manager.GetLoginToken

3. Verify that the command returned:

   Error: GDBus.Error:org.gnome.SettingsDaemon.Smartcard.Manager.Error.FindingSmartcard: User was not logged in with smartcard.

Test XSettings

1. Verify that the a11y bus is available to X11 apps:

   xprop -root AT_SPI_BUS
