[PATCH v3 0/3] cec: One Touch Record tests

[PATCH v3 0/3] cec: One Touch Record tests

[Deborah Brouwer]

This is part of an Outreachy project to expand the testing of
One Touch Record messages as handled by CEC adapters.

Changes since v2:
	Patch 1/3 cec: expand One Touch Record TV Screen test:
	- replace numbers with corresponding defines

	Patch 2/3 cec: expand One Touch Record On/Off tests
	- rename commit to reflect expanded scope of tests
	- increase msg timeout for reply to 10s
	- rename helper function and invert return value
	- use primary device type to identify remote follower
	- use logical address type to identify remote initiator
	- limit range of accepted external plug numbers to 6
	- disallow external physical address source
	- keep track of whether the device is recording
	- add additional invalid tests

	Patch 3/3 cec: add One Touch Record Standby tests
	- new patch

Changes since v1:
	Patch 1/2 cec: expand One Touch Record TV Screen test:
	- add space after 'switch'
	- add "return" before fail
	- check analog broadcast type and broadcast system operand
	- add a comment when follower ignores message
	
	Patch 2/2 cec: expand One Touch Record On test
	- new patch

Deborah Brouwer (3):
  cec: expand One Touch Record TV Screen test
  cec: expand One Touch Record On/Off tests
  cec: add One Touch Record Standby tests

[PATCH v3 1/3] cec: expand One Touch Record TV Screen test

[Deborah Brouwer]

Check that the follower ignores the Record TV Screen message if the
initiator has a logical address other than Record or Backup (aka Reserved
in CEC Version < 2.0). If the follower replies correctly, check that the
source operand is valid.

[PATCH v3 2/3] cec: expand One Touch Record On/Off tests

[Deborah Brouwer]

Send all Record On source operands and check that the follower responds
with a corresponding Record Status. Send invalid Record On operands and
check that the follower returns Feature Abort with Invalid Operand or
Record Status indicating why the recording has failed.

[PATCH v3 3/3] cec: add One Touch Record Standby tests

[Deborah Brouwer]

Check that the recording device ignores a standby message while it is
recording. When the recording is finished, check that the recording device
enters standby unless the recording device is the active source.

You can also check the analog frequency here: corner cases 0x0000 and 0xffff are invalid.

For CEC_OP_RECORD_SRC_EXT_PLUG you can check against the invalid value 0x00.

As discussed in irc I suggest something like this:

	if (rec_status != CEC_OP_RECORD_STATUS_CUR_SRC)
		fail_on_test(!rec_status_is_a_valid_error_status(rec_status));

I.e., if it did not start recording with the current source, then check if
the status is a valid error, otherwise something strange happened and that should
be marked as a failure.

I wouldn't test for these error cases, just add that to rec_status_is_a_valid_error_status().

Ditto.

Reacting to invalid operands shouldn't take 10 seconds, just use the default timeout.
Same below.

Shouldn't this feature abort with invalid op? This looks weird. Same below.

Adding the type argument and wiring it up to process_tuner_record_timer_msgs() should
be done in a separate patch. It's not related to the record tests as such.

Can this be a static function? It's only used in this source, so I think t should be.
Ditto for the similar bool functions below.

Huh? Shouldn't this feature abort with invalid op? Since you provide invalid data here.
