Unified Modeling Language (UML)

• Governed by the Object Management Group (OMG).

• Visualises structure and interactions of a system.

• Used with object-oriented languages such as Java.

• Consists of various diagram types for different purposes.

The Project

6

The Project

Implement and evaluate systematic methods of deriving test suites from UML diagram types.

7

To accomplish this: • Design a system (Requirements and Specification). • Implement the system in java. • Generate different UML diagram types. • Explore methods of generating test suites. • Evaluate the approaches.

Diagram Variance

UML diagrams can display different levels of information about the system at different levels of abstraction.

The variance allows for significantly different methods of generating test suites.

From UML to Test Suites

10

From UML to Test Suites

• Existing literature details numerous methods.

• Possible to explore different approaches to the same diagram type.

• The approach should be abstract from the specific system where possible.

• Test suites should be independent to allow for comparison.

Project Progression

First Term focus:

• System Requirements, Specification

• Implementation

• Beginning of UML diagram formation

14

Next Term focus:

• Completion of system (including UML diagrams)

• Derivation of Test Suites

• Test Suite evaluation
