1. A test system comprising:
a user interface configured to enable user interaction with the system;
a test board configured to communicatively couple with a plurality of devices under test (DUTs), wherein the DUTs are compute express link (CXL) protocol compliant; and
a tester configured to perform direct testing of the plurality of DUTs, wherein the tester comprises a direct access device (DAX) component that prevents corruption of DUTs, wherein the direct access device (DAX) component creates a unique DAX instance for each individual DUT included in the plurality of DUTs.
