Level 3 Test Cases High Level Overview

Below are top test use-case for the Video Display.

# Test-case Description HAL APIs Source Sink
1 Verify the Video Display framerate change with pre-change callback. Play any video content and check the callback is triggered before when the framerate of a display changes dsRegisterFrameratePreChangeCB() NA Y
2 Verify the Video Display framerate change with post-change callback Play any video content and check the callback is triggered after when the framerate of a display changes dsRegisterFrameratePostChangeCB() NA Y
3 Set and verify the Zoom mode of the source device Set the Zoom mode and verify the selected Zoom mode dsSetDFC(), dsGetDFC() Y NA
4 Select the Device Frame Rate of Sink device Select the Device Frame Rate of Sink device and verify dsSetDisplayframerate() NA Y
5 Set and verify the FRF mode Select theFRFmode and verify the selected FRF mode dsSetFRFMode(),dsGetFRFMode() NA Y
6 Check Video coding Formats and information Select the supported video device and the get Video coding format using dsGetSupportedVideoCodingFormats() and get Video codec information for video device using dsGetVideoCodecInfo() dsGetSupportedVideoCodingFormats(),dsGetVideoCodecInfo() Y NA

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.
  • dsVideoDevice
    • This is test helper class which communicates with the L3 C/C++ test running on the DUT through menu
  • L3_TestClasses
    • 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 dsVideoDevice_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 dsVideoDevice_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 dsVideoDevice_test_suite.yml
