Should we check that e.getCause() != null ?

Actually it is null in this case because for the test, rootCause is not provided here (BaseResultIterators):

    throw new SQLExceptionInfo.Builder(OPERATION_TIMED_OUT).setMessage(
            ". Query couldn't be completed in the allotted time: "
                    + queryTimeOut + " ms").build().buildException();

However, I tested by manually adding rootCause and receiving on test side. Hence, it is working fine but since relevant source code does not add root cause, e.getCause() != null would not be true here.

@virajjasani Can we just write a unit test creating OPERATION_TIMED_OUT exception with custom message and custom fake exception. Ideally we wouldn't even need integration test but the test that you wrote is very nice.

Done. Let's keep both unit and IT.
Thanks

Sorry missed this in my previous review.
If there is root cause exception present, you should use this constructor to create SQLtimeoutException

public SQLTimeoutException(String reason,
                   String SQLState,
                   int vendorCode,
                   Throwable cause)
