Level 3 Test Cases High Level Overview

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

# Test-case Description HAL APIs Source Sink
1 Verify that the get temperature function After the device is running for sometime, call getTemperature, and call it after a five minute wait. The two temperatures should not see any noticable changes in temperature dsGetCPUTemperature() Y Y

    note for ut_raft "suite Navigator uses testSuite.yaml"
  • 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.
  • dsHost
  • 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 dsHost_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 dsHost_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 dsHost_testConfig.yml
