=== Automation ===

This test case requires real hardware and is difficult to automate as it requires multiple reboots of the phone.

Radio Settings Tests

Note 1 - Supported radio settings are modem dependant. Response to setting attempt of unsupported technology preference varies between different modems. Modem can either respond with error code or subtly change the setting to value it considers to be close of the requested setting. Also storing responsability of preference may vary between modems. This means that value might be different than what was set with certain modems after bootup. These tests assume that test setup supports edge, hspa, umts and gsm.

Note 2 - Property ModemTechnologies from org.ofono.RadioSettings has changed its name to AvailableTechnologies in upstream ofono, so this test plan will change when ofono 1.16 lands.

1. Verify Interface Availablility / Tech Preference

Purpose

This test case ensures the presence of the org.ofono.RadioSettings interface.

Steps:

1. Run script list-modems. 
2. Check that listed interfaces include org.ofono.RadioSettings with properties 
   TechnologyPreference, ModemTechnologies and FastDormancy. Exact values of properties depend about the 
   previous usage of the tested card, used operator, contract and modem.

Automation Status

Automation of the RadioSettings tests is currently blocked on improvements to the emulator's telephony support.

2. Change technology preference

Purpose

This test case verifies that we can change the radio technology preference. The steps below must be adapted to the actual technologies supported by the modem, which can be seen by using list-modems and checking the value of "AvailableTechnologies" property in the RadioSetting interface.

Steps:

1. Run script set-tech-preference [modem] gsm
2. Run script get-tech-preference [modem]
3. Check that the current technology is “gsm”
4. Run test script list-modems
5. The output of the Technology/Bearer properties must be one of the following values:
       [ org.ofono.NetworkRegistration ]
         Technology = [gsm|edge]
       [ org.ofono.ConnectionManager ]
         Bearer = [gsm|edge]
    Also here note that technology change is not immediate. It takes some time to drop out 
    of old network and connect to another. 
6. Run script set-tech-preference [modem] umts
7. Run script get-tech-preference [modem]
8. Check that the current technology is “umts”. 
9. Run script list-modems
10. The output of the Technology/Bearer properties must eventually have one of the following values:
       [ org.ofono.NetworkRegistration ]
         Technology = [umts|hspa]
       [ org.ofono.ConnectionManager ]
         Bearer = [umts|hsdpa|hsupa|hspa]
   Note that technology change is not immediate. It takes some time to drop out of old
   network and connect to another. 
11. Run test script set-tech-preference [modem] lte
12. Run test script get-tech-preference [modem]
13. Check that the current technology is “lte”. 
14. The output of the Technology/Bearer properties must eventually have one of the following values (see note):
       [ org.ofono.NetworkRegistration ]
         Technology = [umts|hspa]
       [ org.ofono.ConnectionManager ]
         Bearer = lte

Note - if the modem supports data-only LTE but not VoLTE, running list-modems makes ConnectionManager.Bearer drop to umts or gsm. This is due to the fact that list-modems will trigger some supplementary services queries, and as these require voice control channels that are not available via data-only LTE, the modem needs to switch to umts or gsm. In that case to verify the result with existing scripts we have to run list-modems twice (SS queries are cached) or execute monitor-ofono on the background. Note also that if VoLTE is not supported (which we do not for any device at the moment), NetworkRegistration.Technology will never show "lte".

Automation Status

Automation of the RadioSettings tests is currently blocked on improvements to the emulator's telephony support.

3. Check storage of technology preference

Purpose

This test case verifies that the modem stores the radio technology preference between restarts.

Steps

- set-tech-preference [modem] gsm
- get-tech-preference [modem]
# Check that the current technology is “gsm”
- Power off and then on the phone
- get-tech-preference [modem]
# Check that the current technology is “gsm”
- set-tech-preference umts [modem]
- get-tech-preference [modem]
# Check that the current technology is "umts"
- Power off and then on the phone
- get-tech-preference [modem]
# Check that the current technology is "umts"

Note - this is testing the modem itself, not ofono, although it's results are interesting.

Automation

This test case requires real hardware and is difficult to automate as it requires multiple reboots of the phone.
