Finally i resolve the issue of override minicart block for custom module.

you can use below code :

    <blocks>
        <test>
            <class>ABC_Test_Block</class>
        </test>
        <checkout>
            <rewrite>
                <cart_minicart>ABC_Test_Block_Cart_Minicart</cart_minicart>
