When performing property-driven
ant-based builds, if the
abuild.junit.testsuite property is set to the
name of a class, then the test and
check targets will attempt to run a
JUnit-based test suite. JUnit is not bundled with abuild, so
it is the responsibility of the build tree maintainer to supply
the required JUnit JARs to abuild. The easiest way to do this
is to create a plugin that adds the JUnit JARs to
abuild.classpath.external in a
plugin.interface file. For more details on
plugins, please see Chapter 26, Enhancing Abuild with Plugins.
