In order to check taht the wizard is generating a valid action extension and generic action, use the wizard with this files either using the wizard GUI or the command line (giving it the TestActionExtension.xml)

e.g.
cd /tmp
rm -rf /tmp/testwizard
mkdir /tmp/testwizard
~/Atelier/Dev/CamiTK-install-dir/bin/camitk-wizard ~/Dev/CamiTK/camitk/applications/wizard/testdata/TestActionExtension.xml /tmp/testwizard
cd /tmp/testwizard/build
cmake ../testactionextension
make
cd /tmp

other XML files:
ActionExtensionTest.xml
TestActionExtension.xml         sourceDir=../testactionextension
ComponentExtensionTest.xml      sourceDir=../componentextensiontest
