Regression testing on Pop!_OS 22.04 passed:
CLI
Tasks which test the behavior of the CLI client.
- Power profiles can be queried and set
- Switchable graphics can be queried
- Command returns "not supported" message on a non-switchable system
- Command returns
switchableon a laptop with switchable graphics
- Discrete graphics power state can be queried and set (compute mode)
- Works on oryp5 (proprietary firmware); known not to work on oryp6.
GNOME Shell
Tasks which test the behavior of the shell extension.
- Test that the power profile can be switched, and that the dots are correct
- Test that a power profile change from the CLI is reflected in the extension
- When switching to balanced, with screen brightness maxed, screen brightness drops to 40%
- When switching to battery, with screen brightness maxed, screen brightness drops to 10%
- When switching to balanced, with screen brightness minimized, screen brightness does not change
- When restarting the daemon, and the daemon defaults to a balanced profile, the brightness should not change
- When restarting the system, screen brightness should be the same as before
- When plugging in a display in Integrated mode, the system prompts to switch to Hybrid mode
- Switchable system other than galp5
Switchable graphics (test with combination of CLI and GUI)
- Switching from Integrated to NVIDIA
- Switching from Integrated to Hybrid
- Switching from Integrated to Compute
- Switching from NVIDIA to Integrated
- Switching from NVIDIA to Hybrid
- Switching from NVIDIA to Compute
- Switching from Hybrid to Integrated
- Switching from Hybrid to NVIDIA
- Switching from Hybrid to Compute
- Switching from Compute to Integrated
- Switching from Compute to NVIDIA
- Switching from Compute to Hybrid
Graphics switching is still working as expected.
