Automated PDE JUnit Testing With Eclipse 3.3M5

History

After 3.3M4, Modeling builds no longer ran their JUnit tests, due to changes in the way Eclipse packages its startup jars. The fix is trivial, and will be explained below.

[echo] Running org.eclipse.someproject.tests.AllTests
[java] Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/launcher/Main

- or -

[echo] Running org.eclipse.emf.test.build.AllSuites
[java] Unable to access jarfile {dd}/2.3.0/N200701240200/testing/N200701240200/testing/target/eclipse/startup.jar

Migration Guide

• These changes should apply to anyone using PDE for builds & included JUnit tests.

Filename	Explanation	Before	After
runtests	switch from startup.jar to org.eclipse.equinox.launcher_*.jar	cp="eclipse/startup.jar"	cp=`find eclipse/ -name "org.eclipse.equinox.launcher_*.jar" | sort | head -1`
runtests	switch Main classes	org.eclipse.core.launcher.Main	org.eclipse.equinox.launcher.Main

• These changes may be specific to only Modeling project builds, including EMFT builds.

Filename	Explanation	Before	After
relengbuildgtk.sh	don't pass -cp into runtests script to override value set there	runtests -os linux -ws gtk -arch x86 -cp eclipse/startup.jar	runtests -os linux -ws gtk -arch x86
runtests	remove -noupdate flag (not supported anymore)	org.eclipse.*.launcher.Main -noupdate	org.eclipse.*.launcher.Main

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 runtests shell script.
