Level 3 Test Cases High Level Overview

# Streams Name Streams description
1 vts_SDR_stream Format: SDR,Resolution: 1920 x 1080

Below are top test use-case for the Composite Input.

# Test-case Description Focus APIs
1 Verify the CompositeIn port connection with callbacks Connect/disconnect the CompositeIn source device on each of compositeIn port and check the callbacks is triggered when the connection status changes dsCompositeInRegisterConnectCB()
2 Verify the CompositeIn active port status with callbacks Connect a CompositeIn source device, select the CompositeIn port and check the callbacks is triggered when the active status changes(i.e like isPresented, activeport) dsCompositeInRegisterStatusChangeCB()
3 Scale the video and verify Play the video stream(vts_SDR_stream) in CompositeIn source device connected to the active CompositeIn port and scale the video resolution dsCompositeInScaleVideo()
4 Verify the CompositeIn Signal change with callback Connect a CompositeIn source device, select the CompositeIn port and check the callback is triggered when the change in signal status occurs(i.e like no signal , unstable signal, stable signal) dsCompositeInRegisterSignalChangeCB()
5 Verify the CompositeIn video mode change with callback Connect a CompositeIn source device, select the CompositeIn port, and verify that the callback is triggered when there is a change in the video mode on the source device dsCompositeInRegisterVideoModeUpdateCB()

  • 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.
  • dsCompositeIn
  • 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 dsCompositeIn_Settings

  • testSetupConfig.yaml

  • This configuration file contains the list of requirements for tests to execute. Eg: Copying the streams etc.

  • Example configuration file dsCompositeIn_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 dsCompositeIn_testConfig.yml
