commit 1325e60fc900dfb1cd0438d858d72ca4ecd698df
Author: Liang Zhang <zhangli...@apache.org>
AuthorDate: Wed Oct 29 00:49:52 2025 +0800

    Add test coverage for ComputeNodeInstance class (#36958)
    
    - Create ComputeNodeInstanceTest with 2 test methods
    - Test switchState() method for both CIRCUIT_BREAK and other states
    - Use simple mock() calls without complex stubbing
    - Verify state transitions with assertThat() assertions
    - Achieve 100% coverage for custom business logic
    - Follow minimal test design principles
