View source for Automated PDE JUnit Testing With Eclipse 3.3M5


== History ==

After 3.3M4, Modeling builds [https://bugs.eclipse.org/bugs/show_bug.cgi?id=170831 no longer ran their JUnit tests], due to changes in the way Eclipse packages its startup jars. The fix is trivial, but requires a change to [http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.test/library.xml?view=log org.eclipse.test/library.xml] in addition to your local releng code.

* These changes apply to you if you use org.eclipse.test (eg., in your map file, or if you run org.eclipse.test/library.xml).


 plugin@org.eclipse.test=v20070217,:pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse,


This is fixed by moving up to the latest version (v20070217) of [http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.test/library.xml?view=log org.eclipse.test/library.xml], per [https://bugs.eclipse.org/bugs/show_bug.cgi?id=171756 bug 171756].

== Running Tests ==

To run tests, you'll need something like this:

 $JAVA_HOME/bin/java $Xflags -enableassertions -cp $cp \
   org.eclipse.equinox.launcher.Main -ws $ws -os $os -arch $arch \
   -application org.eclipse.ant.core.antRunner -data $workspaceDir \
   -file test.xml $antTestTarget \
   $Dflags -Dws=$ws -Dos=$os -Darch=$arch -D$installmode=true $J2SE15flags \
   $properties -logger org.apache.tools.ant.DefaultLogger

The variables noted in the above example can be seen in detail in the [http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.mdt/org.eclipse.ocl.releng/builder/tests/scripts/runtests?root=Modeling_Project&view=markup runtests] shell script.
