Level 3 Test Cases High Level Overview

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

# Test-case Description HAL APIs Source Sink Streams Number
1 Verify the Video Display framerate change with pre and post change callback. Set the auto framerate mode and check the callback is triggered before and after when the framerate of a display changes dsRegisterFrameratePreChangeCB(), dsRegisterFrameratePostChangeCB() NA Y 1,2,3,4,5,6,7,8
2 Set and verify the Zoom mode of the source device Play any video content and Set the supported Zoom mode and verify the selected Zoom mode dsSetDFC(), dsGetDFC() Y NA 9
3 Select the Device Frame Rate of Sink device Select the Device Frame Rate of Sink device and on playing video playback verify dsSetDisplayframerate() dsSetDisplayframerate() NA Y 1,2,3,4,5,6,7,8
4 Set and verify the FRF mode Select theFRFmode and verify the selected FRF mode with video playback dsSetFRFMode() NA Y 1,2,3,4,5,6,7,8

  • 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

  • testConfig.yaml

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