Verify Power Limits
    [Documentation]  Set power levels and verify limits.

    Set DCMI Power Limit And Verify  ${mid_power}
    Test Power Limit  ${min_power}  ${below_min_power}
    Test Power Limit  ${min_power}  ${zero_power}

Test Power Limit
    [Documentation]  Set power and check limit.
    [Arguments]  ${good_power}  ${outside_bounds_power}

    # Description of argument(s):
    # good_power              A valid power setting, usually at a limit.
    # outside_bounds_power    A power level that is beyond the limit.

    Set DCMI Power Limit And Verify  ${good_power}

    # Try to set out of bounds.
    ${expected_error}=  Set Variable
    ...  Failed setting dcmi power limit to ${outside_bounds_power} watts.
    Run Keyword and Expect Error  ${expected_error}

Suite Setup Execution
    [Documentation]  Do test setup initialization.

    ${cmd}=  Catenate  dcmi power get_limit | grep State
    ${resp}=  Run External IPMI Standard Command  ${cmd}
    # Response is either "Power Limit Active" or "No Active Power Limit".
    ${initial_deactivation}=  Get Count  ${resp}  No
    # If deactivated: initial_deactivation = 1, 0 otherwise.
    Set Suite Variable  ${initial_deactivation}  children=true

    # Save the power limit setting.
    ${initial_power_setting}=  Get DCMI Power Limit
    Set Suite Variable  ${initial_power_setting}  children=true


Test Teardown Execution
    [Documentation]  Do the post test teardown.
