    # @brief This is a common function for all the PRD test cases. This will be executed before
    #        any test case starts. Basically this provides below requirements.
    #        1. Validates all required host commands
    #        2. It will clone skiboot source repository
    #        3. Compile the necessary tools -xscom-utils(getscom and putscom)
    #        4. Get the list Of Chips.
    #           Ex: ['00000000', '00000001', '00000010']
    #        5. generate a random chip.
