Each test case need to verify with the each HdmiIn port. Below are top test use-case for the HdmiIn port.

# Test-case Description Focus APIs Source Sink
1 Verify the HdmiIn Connect status with callback Connect or Disconnect HdmiInput device on each of the HdmiInput ports and check the hdmiInConnectCB callback is triggered dsHdmiInRegisterConnectCB() Y Y
2 Verify the HdmiIn Signal change with callback Select the HdmiInput port and check the callback is triggered when the change in signal status occurs(i.e like no signal , unstable signal, stable signal dsHdmiInRegisterSignalChangeCB() NA Y
3 Verify the HdmiIn Status change with callback Select the HdmiInput port and check the callback is triggered when the status change occurs(i.e like isPresented, activeport) and check the callbacks is triggered dsHdmiInRegisterStatusChangeCB() NA Y
4 Verify the HdmiIn Video Mode update with callback Select the Hdminput device with different resolutions , aspect ratio and check the callbacks is triggered and outputs the same resolution , aspect ratio dsHdmiInRegisterVideoModeUpdateCB() NA Y
5 Verify the HdmiIn ALLM change with callback Change the ALLM option to TRUE/FALSE after connecting game controller on 4k supported panel and check the callbacks is triggered when the ALLM status change occurs dsHdmiInRegisterAllmChangeCB() NA Y
6 Verify the HdmiIn Audio Video lateny with callback Select the Hdminput device with available resolutions (like HDR,HLG,DolbyVision,SDR,...) and check the callbacks is triggered when there is latency change dsHdmiInRegisterAVLatencyChangeCB() NA Y
7 Verify the HdmiIn AVI content change with callbacks Play the streams from Hdminput device with differenct formats(like GRAPHICS,PHOTO,CINEMA,GAME,...) and check the callbacks is triggered when there is AVI content change dsHdmiInRegisterAviContentTypeChangeCB() NA Y
8 Get HdmiIn status of the selected port Select the HdmiInput and verify the status whether selected port active or not dsHdmiInSelectPort(),dsHdmiInGetStatus() Y Y
9 Scale HdmiIn video of the selected port Select the HdmiInput and scale the video on the selcted port verify video scaled or not dsHdmiInScaleVideo() Y Y
10 Check and verify Zoom mode selected Select the Zoom mode from the available inputs and verify its set or not dsHdmiInSelectZoomMode() Y NA
11 Get and verify the EDID of selected port Select the HdmiInput and get the EDID for that particular Input port dsGetEDIDBytesInfo() NA Y
12 Get and verify the SPD info of selected port Select the HdmiInput and get the SPD info for that particular Input port dsGetHDMISPDInfo() NA Y
13 Set and verify the EDID version on selected port Set the EDID version and verify by retrieving the EDID version dsSetEdidVersion(),dsGetEdidVersion() NA Y
14 Set and verify EDID to ALLM support on selected port Set and retrieve ALLM on selected port connected with game controller on 4k supported panel dsSetEdid2AllmSupport(),dsGetEdid2AllmSupport() NA Y

Loading
  • testControl
    • Test Control Module for running rack Testing. This module configures the DUT based on the rack configuration file provided to the test.
    • This class is defined in RAFT framework. For more details refer RAFT
  • ut_raft
    • Python based testing framework for writing engineering tests.
    • It provides common functionalities like menu navigation, configuration reader, reading user response etc.
    • For more details ut-raft.
  • dsHdmiIn
    • This is test helper class which communicates with the L3 C/C++ test running on the DUT through menu
  • L3TestClasses
    • These are the L3 test case classes
    • Each class covers the each test use-case defined in L3 Test use-cases table

YAML File Inputs

  • rackConfig.yaml

    • Identifies the rack configuration and platform used
    • References platform-specific config from deviceConfig.yaml
    • For more details refer RAFT and example_rack_config.yml

  • deviceConfig.yaml

    • Specifies overall configuration for the platform
    • Can be overridden by:
      • Changing locally .yaml file directory
      • Using --deviceConfig command line switch
    • For more details refer RAFT and example_device_config.yml

  • componentProfile.yaml/platformProfile.yaml

    • Contains component-specific configurations
    • Contains platform wide configuration broken down into separate components
    • Example configuration file dsHdmiIn_Settings

  • testSetupConfig.yaml

    • This configuration file contains the list of requirements for tests to execute. Eg: Copying the streams, setting environment variables etc.
    • Example configuration file dsHdmiIn_L3_testSetup.yml

  • testSuite.yaml

    • This configuration file contains the list of menu items for C/C++ L3 test running on DUT
    • Example configuration file dsHdmiIn_test_suite.yml
