#set( $symbol_pound = '#' )

#set( $symbol_dollar = '$' )

#set( $symbol_escape = '\' )

For each class you are going to test, create one Test class with the same

name as the class to test, ending with Test.

For example, the unit tests of the "ExampleLibrary" class are performed

by the "ExampleLibraryTest" class.

#set( $symbol_pound = '#' )

#set( $symbol_dollar = '$' )

#set( $symbol_escape = '\' )

Put into this folder the resources needed by your test classes.

This folder is added to the Tests classpath, so you can load any resources 

through the ClassLoader.

By default, in this folder you can find an example of log4j configuration,

prepared to log messages through the console, so logging works when you

run your tests classes.

This package contains some common gui widgets such as a directory chooser,

a font chooser, a generic message dialog box etc.

</p>

<p>

All widgets are Thinlet widgets.

</p>

<p>

Note that the <code>thinletcommons</code> package does not depend on the

<code>thing</code> package, so these widgets could be used in other

applications.
