Overview of Protocol Test Suite

Why We Developed Protocol Test Suites Ensure quality of Microsoft protocol documentation (Open Specification) Help to Identify your implementation issues Make debugging easier Easier environment Encrypted messages logging Include negative test cases Source code of test suite could be your reference in development phase

Test Methodology in Protocol Test Suite

RDP Protocol Test Suite Architecture System Under Test (SUT) RDP Synthetic Server (Test Suite) RDP Client SUT Control Adapter Test Case TCP/UDP TCP/UDP

SUT Control Adapter Purpose Types: The interface defines methods for changing or querying SUT status dynamically at runtime. public interface IRdpSutControlAdapter : IAdapter { …….. int RDPConnectWithNegotiationAppoach(); int TriggerClientDisconnect(); int TriggerClientAutoReconnect(); int TriggerInputEvents(); } Types: PowerShell Interactive Protocol-based

SUT Control Adapter -- PowerShell Map interface methods to PowerShell Scripts Run

SUT Control Adapter -- Interactive Control the SUT manually When a method is called: A dialog pops up User controls SUT manually Clicks the “Continue” button

SUT Control Adapter -- Protocol-based A simple self-defined protocol (SUT remote control protocol) used to transfer control commands and results. User needs to implement a simple program as an Agent to control System Under Test (SUT) RDP Protocols Test Cases RDP Client Advantage: Automation on any system No work on test suite Implement in any program language SUT Remote Control Protocol SUT Control Request Message SUT control adapter Agent SUT Control Response Message
