Network Example

We will be experimenting with acceptance testing technique using radio network routing algorithms as a sufficiently complicated example. Our testbed will be a recently reincarnated simulation which we have described briefly elsewhere. http://c2.com/~ward/mors ... Net/SimView.html. -- WardCunningham

The simulator starts with no nodes. The new city button pops up a dialog for city information. Try http:run.cgi.

fit.ActionFixture

start eg.net.Simulator

check nodes 0

press new city

enter name Portland

enter zip 1,1,1

enter population 1.5e6

enter coord 45 30.0 n 122 45.0 w

check coord N45.5 W122.75

press ok

check nodes 1

press new city

enter name Salem

enter population .6e6

enter zip 1,1,2

enter coord 44 59' 22" n 122 28' 59" w

press ok

check nodes 2

press new city

enter name Seattle

press cancel

check nodes 2

An ActionFixture delegates much of its work to other fixtures (actors). See the source for the actor(s) in use here.

http:Release/Source/eg/net/Simulator.java

This fixture employs a domain specific ValueObject called a GeoCoordinate. The framework goes to some lenght to make sure such objects can be parsed and printed within the framework. Actual parsing and printing are easily delegated to the domain object, as they are here by GeoCoordinate, which accepts a wide variety of coordinate notations.
