1. STF 454 TDL – Overview Last change: 2013-05-08
© ETSI All rights reserved

2. Design aspects
Considering the recommendations of previous ETSI activity on HLTD
TDL should be easy-to-use
Mandatory and optional language elements
TDL should be open for further extensions
Test data specified in any language should be used in TDL
© ETSI All rights reserved

3. Comments/Annotations
Comments can be added to any TDL elements
Except for comments
Annotations allow to attach user/tool specific extensions, hints to TDL elements
To support code generation
To add new language elements
Packages

4. Test Data
Data types, messages, templates etc. defined in any language can be used
There is no internal data type specification in TDL
But may be added later if needed
Consequence:
Data is treated as strings in TDL
Tool-specific syntax/semantics checking

8. Test Behaviour – Combined Behaviour
Combined behaviours:
Alternative
Tester receiving
Conditional
Tester send
(“if then else”)
Parallel
Loops
Bounded (“for”)
Unbounded (“while”)

9. Test Behaviour – Exceptional/Periodic
Starts by Tester receive event
Default
Interrupt
Periodic
Starts by Tester send event
Executed in parallel with the behaviour of the containing combined behaviour
