摘　　要：Link 16为美国三军主用数据链装备,其消息标准与作战应用紧密结合,具有消息种类多、消息实现复杂等特点。文章在分析Link 16消息标准的基础上,提出一种Link 16数据链协议一致性测试方法。首先,阐述数据链协议一致性测试原理;其次,针对消息处理的复杂性,提出基于因果图的测试用例设计方法,确保测试用例能够有效覆盖消息处理路径;最后,详细论述本地操作员触发的测试方法和远端消息触发的测试方法,实现消息编解码、收发规则、战术功能处理等方面的测试,保证了消息实现与消息标准一致。Link 16 is main data link equipment of American army. Message standard of Link 16 includes many kinds of messages and its implementation is complex, because it relates to operation. A conformance test method of Link 16 was brought forward based on analysis of message standard. Firstly, the protocol conformance test elements of data link were described. Secondly, the test case design method based on cause-effect dia- gram was brought forward to assure that test case cover message process paths because of complexity of mes- sage processing. Lastly, the test methods stimulated by operator and remote message are described in order to test message coding, sending and receiving rules, tactical function. This method guarantees that message implementation conforms to message standard.
