READING:

Browse PART 3 of the textbook. 

Browse www.rational.com/uml for the specification
of UML class diagrams.

Read the AP Studio documentation
http://www.ccs.neu.edu/research/demeter/APStudio/UserManual/

Read about StructureBuilder at www.tendril.com
You may want to download StructureBuilder into your PC for the purpose
of this homework. 


Testing a graphical user interface
==================================

The theme of this homework is to show you the issues of testing a graphical user interface.
The topic of the graphical user interface is to draw class diagrams using the 
Unified Modeling Language (UML).
Class diagrams in particular, are described at:
http://www.rational.com/uml/html/notation/notation5a.html#5.1
and UML in general is described at 
http://www.rational.com/uml/
Those pages constitute the UML class diagram specification.

You test two programs which are graphical user
interfaces for drawing UML class diagrams.

The first program, AP Studio, is a program developed by Kedar Patankar and Binoy
Samuel of the College of Computer Science. It is the same
program you already used in homework 2.
/proj/demsys/apstudio/bin/apstudio/

Documentation about AP Studio is available from the Help menu in AP Studio
(upper right corner) or from:

http://www.ccs.neu.edu/research/demeter/APStudio/UserManual/

The version on the web seems to be easier to read using your favorite browswer.

The second program, StructureBuilder, is a commercial program developed by
Tendril Software, Inc. 
www.tendril.com
I know the people who develop StructureBuilder
and there is also a Northeastern connection: Before Tendril was started,
one of the founders, Neeraj Sangal, spent a few months in the
College of Computer Science.
To run StructureBuilder, use
/proj/demsys/StructureBuilder/runSBu

Documentation about StructureBuilder is available at www.tendril.com

If you find bugs in those programs, they will be forwarded to the developers.

In this homework you test the capability of drawing UML class diagrams
from scratch. You start with an empty canvas and enter several class
diagrams having the following features:

Concrete classes
Abstract classes
Directed associations with cardinalities
Association of a class with itself (self loop)


Simplifying assumptions:

No methods

No parameterized classes (template classes).

No qualified associations.

No association classes.

What to turn in:

Test requirements
Test specifications
Outputs (Postscript files) and in the case of AP Studio, the textual version of your graphs.
Bug reports



Special requirements for AP Studio:

There is a chance that StructureBuilder does not work with your
.software file. In that case, copy

/home/lieber/.software-kedar

into your .software file.
