Introduction

Overview of ETSI Test Languages

Design Considerations of TDL

Structure of TDL

• Language Constructs of TDL

• Graphical Representation of TDL

TDL: Present and Future

Contents

Telecommunications systems become more and more complex

• Complex architecture (system of systems)

• Complex behaviour (concurrency, complex protocols)

• Complex data (complex data structure, „big data”)

... and these systems shall be tested

Testing

What to test?

• Test purposes

How to test?

• Test configuration

Which data to test with?

• Test data specification

What the test shall contain?

• Test behaviour description

Testing

• Describes Test Purposes

• „List of wishes”

TTCN-3

• Testprogram

Missing…

• Something between the two abstraction levels

• Which can be used also by non-programmers

• Graphical

TDL – Test Description Language

Test design

Test documentation

Test representation

One language throughout the whole development cycle

Specification

TDL Standard

Well-defined language constructs

• UML MOF-based description

Makes it possible to develop different domain-specific concrete syntaxes

Meta-model

Test Data

Time, Timers

Test Configuration

Test Behaviour

Test Objectives

Structure of TDL

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

Test Description Test Behaviour Elements

TDL meta-model

Abstract data

Simple and Structured Data (declarative)

• Mandatory and optional fields

Can be mapped to ‘real’ data implementation

Test data

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

• Time Labels

• Time Constraints

• Wait

Timers

• Definition

• Operations

• start, stop, timeout

Time, Timers

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

Components and Gates (Interfaces)

TESTER and SUT roles

Connections between Gates

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

Test Description

• ~ Testcase

Contains:

• Test Objective

• Test Configuration

• Test Behaviour

Test Behaviour

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

TDL describes the expected behaviour

• Any deviation – automatic fail verdict

• Can be overwritten by explicit verdict setting

• Pre-defined verdicts: pass, fail, inconclusive

• Extensible

Atomic Behaviours

• Interaction

• generalized communication

• Action, Function Call, Assignment

• Call other Test Descriptions

• Explicit verdict setting

• Assertion

• Stop

Test Behaviour

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

Combined Behaviours

• Sequential (Compound)

• Parallel

• Alternative

• Conditional (~if..then..else)

• Cycles

• For

• While

• Periodical

• Handling of non-expected behaviour

• Default

Test Behaviour

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

Definition of Test Objectives

• Textual description

• Reference to test documents

At behaviour description the satisfied test objective can be indicated

Test Objectives

Test Configuration

Test Objective

Data TimeFoundation

Test Behaviour

TDL meta-model

Similar approach to UML SD

New symbols to new constructs

Graphical symbols

• Formal description of the contained text

Graphical Syntax

Data Specification

Test Configuration

Test Behaviour

Goals:

• Interoperability between tools

• Interoperability between different concrete syntaxes

XMI (XML Metadata Interchange)

• To serialize the meta-model

• Syntactical check possible

• For semantic check constraints described in meta-model shall also be considered

Transfer Syntax

Goals:

• Formalize the description of test purposes

• Unify the content

• Possibility of automatic validation

• Preserving the compatibility with TPLan

Structured Test Objective Specification

Test Objective

Reference

TP/GEONW/FDV/BAH/BV/01

Check defined values of default Gn parameters in the basic header

PICS Selection PICS_F1

Initial Conditions

Expected Behaviour

with {

the IUT entity being in the initial state

ensure that{

when {

the IUT entity is requested to send a "GUC packet"

then {

the IUT entity sends a "GUC packet" containing

BasicHeader containing

"version field" indicating value "itsGnProtocolVersion MIB parameter" ,

"RHL field" indicating value "itsGnDefaultHopLimit MIB parameter"

Final Conditions

ETSI Standard

TDL v1 – 2013

TDL v2 – Multi-part Standard

TDL v3

• Reference editor

• UML profile

TDL v4

• TDL -> TTCN-3 Mapping

TDL: Present and Future

One language throughout the whole development cycle

Easy-to-use, Easy-to-learn

Graphical

Supports different abstraction levels

• From very high level to close to implementation

At different standardisation/industry areas

• Telecommunication, Internet, Vehicle, Medical, etc.

• Simple and structured systems
