Setting up TUnit

Minimum Requirements

The minimum requirements are:

• Install the latest tinyos-2.x, or get it from the repository.
• Check out a copy of the latest tinyos-2.x-contrib repository (instructions here).
• Ant is completely optional, but may be used to generate nicer looking HTML reports.

Simplistic Directory Structure

Your projects and directories may differ. On the automated unit testing server, the tinyos-2.x and tinyos-2.x-contrib directories are located in a simplistic structure:

 opt
 |-- tinyos-2.x
 |-- tinyos-2.x-contrib

Complex Directory Structure

In my own private projects, I prefer a more complex structure:

 opt
 |-- myProject
 |   |-- tinyos-2.x    <-- A snapshot of TinyOS my project is compatible with
 |   |-- tests
 |   |   |-- ... bunch of sub-test directories...
 |   |-- tinyos-2.x-myProject    <-- Project's files that override the TinyOS baseline
 |   
 |-- tinyos-2.x-contrib

For the remainder of this setup guide, I will assume your TinyOS is setup in the simplistic structure, with directories located at /opt/tinyos-2.x and /opt/tinyos-2.x-contrib.

Environment Variables

TOSCONTRIB

TUnit needs to know where the tinyos-2.x-contrib is located so it may find the tinyos-2.x-contrib/tunit directory. Because TUnit is driven by a Java application, the TOSCONTRIB path must be absolute so Java can locate the directory.

 Linux
   export TOSCONTRIB=/opt/tinyos-2.x-contrib

 Windows/Cygwin
   export TOSCONTRIB="`cygpath -w /opt/tinyos-2.x-contrib`"

CLASSPATH

Your classpath must be updated to include tunit.jar and all of its dependencies.

 Linux
   export LOG4J=$TOSCONTRIB/tunit/support/sdk/tunit/depends/log4j.jar
   export TUNIT=$TOSCONTRIB/tunit/support/sdk/tunit/tunit.jar
   export XERCES=$TOSCONTRIB/tunit/support/sdk/tunit/depends/xerces.jar
   export JFREECHART=$TOSCONTRIB/tunit/support/sdk/tunit/depends/jfreechart-1.0.5.jar
   export JCOMMON=$TOSCONTRIB/tunit/support/sdk/tunit/depends/jcommon-1.0.9.jar
 
   export CLASSPATH="${CLASSPATH}:${LOG4J}:${TUNIT}:${XERCES}:${JFREECHART}:${JCOMMON}:."

 Windows/Cygwin
   export LOG4J="`cygpath -w $TOSCONTRIB/tunit/support/sdk/tunit/depends/log4j.jar`"
   export TUNIT="`cygpath -w $TOSCONTRIB/tunit/support/sdk/tunit/tunit.jar`"
   export XERCES="`cygpath -w $TOSCONTRIB/tunit/support/sdk/tunit/depends/xerces.jar`"
   export JFREECHART="`cygpath -w $TOSCONTRIB/tunit/support/sdk/tunit/depends/jfreechart-1.0.5.jar`"
   export JCOMMON="`cygpath -w $TOSCONTRIB/tunit/support/sdk/tunit/depends/jcommon-1.0.9.jar`"
 
   export CLASSPATH="${CLASSPATH};${LOG4J};${TUNIT};${XERCES};${JFREECHART};${JCOMMON};."
