Q&A

3. Overview of Protocol Test Suite

4. 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

5. Test Methodology in Protocol Test Suite

6. RDP Protocol Test Suite

7. RDP Protocol Test Suite
Test Target: RDP Client
Synthetic RDP Server
Align with Win10 document
Source Code (C#)

10. 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

11. 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

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

13. 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

14. 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
