RemoteFX Protocol Test Suite

• Protocol Test Suite – Why ,What, How

• RemoteFX Test Suite Introduction

• How to use RemoteFX Test Suite

Let this video tell you…

Goals:

• Ensure quality of MS protocol documentation(Open Specification)

o Accuracy and usability

• Help to Identify your implementation issues

o Make debugging easier

Message sequence

Encrypted messages logging

o Handle negative test cases

• Source code in test suite can be your reference in dev phase

New Protocols/Features Coverage

• Protocol Test Suite – Why ,What, How

• RemoteFX Test Suite Introduction

• How to use RemoteFX Test Suite

• The test target is RDP Client

• The test suite is Synthetic RDP Server

• Aligned with Windows 8.1 document

• More than 200 test cases, including positive and negative

• Test Code (C#) can be your reference, such as codecs

• Test most of features in covered protocols

• Highlighted tested features since Windows 8

AdapterTest Cases

Protocol Specification:

If RDP server sends message A to RDP client, RDP client should respond with message B.

If A is invalid, client should return error message C.

Test Case 1:

1. Establish RDP connection;

2. Server.Send(msgA);

3. Expect client respond msgB, and

• Assert (msgB.Field1 == valid1)

• Assert (msgB.Field2 == valid2)

• …

• Assert (msgB.FieldN == validN)

Test Case 2:

1. Establish RDP connection;

2. Server.Send(Invalid msgA);

3. Expect client respond msgC, and

• Assert (msgC.Satus == ERROR)

RemoteFX Interop Test Suite

Common Deployment Steps:

• Install RDP client on SUT

• Install Test Suite on Test Suite Host

• Configure Test Suite

• Protocol Test Suite – Why ,What, How

• RemoteFX Test Suite Introduction

• How to use RemoteFX Test Suite

• Purpose:• The interface defines methods for changing or

querying SUT states dynamically at runtime.

• Types: Protocol-based

Transport for RDP protocols

Agent

• Self-defined a simple protocol to transfer control commands and result.

• User needs to implement a simple program as an Agent to control SUT (System Under Test)

SUT Control Request Message

SUT Control Response Message

Operate

• Build automatic test environment on any system

• User doesn’t need to do any work on test suite

• User need to develop an Agent program on SUT The Agent program can be powerful and flexible

The workload of development is low

The protocol we defined is very simple

The Agent program is on SUT, same environment as your RDP client product

• Maps interface methods to PowerShell scripts.

• The implementation will run the corresponding script file when one of the adapter's methods is called.

Interface Script files

When a method is called:

• Control the SUT manually

• Is used when other automatic control method is not supported

A dialog is popped up

User controls SUT manually

User clicks the “Continue” button

• Protocol Test Manager (PTM) is a unified UI for protocol test suites.

• Besides running test cases, PTM also includes: Test suite introduction

Auto-Detect Supported features

Automatic configure test suite

Classify and filter test cases

View test result

Will show you more details in Demo Session

• To investigate test case failure, you always need run-time information like:• Test case log - From log file

• Network traffic - Captured by MessageAnalyzer/Netmon

• Encrypted or compressed message – From Visual Studio

• Using MessageAnalyzer to combine all these information• See all valuable information from one window.
