  1. Alain-G. Vouffo Feudjio FOKUS’ View on MODEL-Based Test Description Languages (TDLs)

  2. Outline • Motivations: Why Model-Based Test Design • FOKUS’ View on TDL by Example • Discussion

  3. Why Model-Based Test Description (I) • Test design at early phase of the product lifecycle • Enhanced reuse of test design. • Facilitated communication between stakeholders. • Facilitated integration of testing in MDE process by filling the gap between requirements and testing. • Higher quality of test specifications through Application and Automated Verification of Test Design Guidelines. • Unified and test execution platform-independent test design. • Facilitated Reuse of legacy test scripts through Round-Trip Engineering in Test Automation. • E.g. Visualization of legacy test scripts for reuse.

  4. Why Model-Based Test Description (II) • Requirements traceability. • Early identification of flaws in system specification. • Integration of test-related activities in the overall MDE process. • Time savings, Costs reduction • Automated generation of executable test scripts through model-to-model (M2M) or model-to-text (M2T) transformations from system model to test model and backwards.

  5. Model-Based Test Design: Process Test Model Test Objectives Model Test Architecture Model System Description DSMLs Requirements Test Suite TTCN-3 Test Procedures Model Test Data Model Executable Testcases or Skeletons Informal System/Test Specification Test Behaviour Model Test Documentation System Model (Automated) Test Model Transformation Model-Based Test Design Optional

  6. The UTML Notation as a TDL • FOKUS follows a two-way approach to test modeling/designing • A pure UML approach (UTP) based • A UML-Like approach based on a DSML called UTML (Unified Test Modeling Language) • UTML combines concepts of TTCN-3, UML (TP) and SysML into a DSML for designing tests at high level of abstraction • Based on an EMF (eMOF) Meta-Model • Currently supports 3 representation formats • Tree & Tabular • Graphical • Allows a Formalization and exploitation of patterns in test design to guide and speed up the process

  7. Model-Based Test Design: ITS DENM Example

  8. Model-Based Test Design: Test Objective/Purpose Design

  9. Model-Based Test Design: Test Architecture Design

  10. Model-Based Test Design: Test Behaviour Design Don‘t worry: You will NOT have to enter this as source code. It‘s just a label created out of the provided model elements.

  11. Model-Based Test Design: Test Behaviour Design using Activity Diagram Don‘t worry: You will NOT have to enter this as source code. It‘s just a label created out of the provided model elements.

  12. Model-Based Test Design: Transformation

  13. A Few Remarks • Models are transformed. Therefore, only information contained therein can be transformed or exploited • Models may provide different Levels of detail. Obviously, the ability to generate automatically executable test cases will depend on the completeness of the information provided in the modelling • The test models may be used by model-based test generation to apply combinatory algorithms for generating a larger number of variants of the test case, although those would be functionally equivalent (From a conformance testing perspective) • As any matter of taste, obviously the graphical diagram elements may be more or less appreciated, depending on the organization and the individual, but they can be considered as inter-changeable. Focus should be laid on the concepts, rather than their representation

  14. TDL: Goals of standardization • Define a standardized concept space as • MOF/EMF Metamodel ? • Other ? • Define and standardize • Representation formats? • Graphical visualization concepts? • Textual syntax?
