Protocol testing is the procedure which is followed to test the functionality of features and products which are available on a networking or security platform. Protocol testing engineers are required to validate the required functionality before the device is shipped. Protocol testing broadly includes the three testing types as follows.
1. Functionality Testing – This testing validates if the functionality of the required feature (ex: VLAN, RIP) on the devices functions as required. The engineer refers design documents to prepare test plans and test cases for functionality testing.
2. Conformance Testing – This testing validates if the protocol under test like RIP, OSPF etc, adheres to conformance standards like RFC, IEEE etc. Test plans and cases are prepared referring appropriate documents from the standards
3. Performance Testing – This testing validates if the device withstands performance testing benchmarks. Custom tools are made with automation languages like Python, TCL or commercial tools like Ixia, Spirent can also be used for the purpose.
