Embodiment Construction

[0023] In order to more clearly reflect the specific execution process of the network protocol performance testing method based on TTCN of the present invention and the application of the control protocol message in the protocol performance test, the test control message design of three representative performance test cases is introduced here , and describe in detail the testing process of one of the performance test cases.

[0024] In the TCP connection response time performance test, there is no need to design a control protocol, because the TCP protocol is a connection-oriented protocol, which itself has an interactive function. The test end uses the SYN and SYN_ACK messages in the TCP handshake process to count the TCP connection response time between the test system and the system under test. The performance test of the DHCP protocol and the UDP protocol needs to design a control protocol, because these two protocols do not have interactive functions. However, due to the...

Abstract

The invention discloses a tree and tabular combined notation (TTCN)-based network protocol performance testing method, which comprises the following steps of: (1) writing test cases, corresponding adapters and corresponding codecs, and selectively designing test control messages in the test cases according to test objects; (2) selecting the test case according to network protocol performance parameters to be tested; (3) performing test configuration according to the test case; (4) compiling the test case by adopting a TTCN platform, and registering the adapter and the codec by using a testingsystem; (5) running the test case and acquiring test records; and (6) performing record counting analysis on the test, and giving a performance test report. The method is applied to ordinary protocolperformance tests; and in the method, a protocol performance testing process is put forward and normalized, and simultaneously a control protocol is selectively applied to the TTCN-based protocol performance test so as to reduce difficulties in the protocol performance test and improve the understandability and reusability of the test.

Description

technical field [0001] The invention relates to the field of software testing, in particular to the field of performance testing in network communication protocol testing. Background technique [0002] A network protocol is an agreement that computer systems must abide by when exchanging information. Any type of network service cannot do without the support of a specific network protocol. Since the TCP / IP protocol family has become the de facto international standard of the Internet, new network applications have emerged continuously. [0003] The functions of the network protocol can be implemented by software or hardware. Most network protocol standard documents, such as the RFC series standards that contain almost all important protocols on the Internet, are described in artificial language. Engineers have different understandings of the same set of network protocols, resulting in different protocol implementations. At the same time, considering the variety and complex...
