5. The complexity of post-trade
   - There is a multitude of components in modern
   complex post-trade infrastructures;
   - Upstream and downstream system dependency;
   - The participant structure is very complex;
   - Trade/Position/Account life cycle;
   - The number of Asset Classes may vary;
   - The complexity of the Risk calculation process;
   - Access via a set of API endpoints.

12. Exactpro Test Framework and Test Approach for
    DLT-based system
    3 steps on the ledger side:
    1st - Initialisation of positions
    2nd - Trade creation and participant
    notification
    3rd - Positions updates
    Across each and every step the test
    framework provides different methods
    to validate the endpoints, inputs and
    outputs.
    The actual business flow steps and
    validation check items are transformed
    into ClearTH matrix after execution of
    which the deviations from the
    expected behaviour can be analysed.

13. ClearTH and Woodpecker for DLT
    is an Exactpro test harness able to simultaneously
    execute multiple end-to-end test scenarios in
    batches.
    ● Supports multiple protocols (SWIFT, FIX,
    Market Data, etc.)
    ● Automatically runs test scripts
    ● Executes concurrent automated tests
    ● Allows to create multiple-day test scenarios
    ● Has integrated scheduler and simulators
    ● Verifies each stage of the system daily life cycle
