Re: [tycho-user] Running eclipse plugin test that depends on an Eclipse

["Sievers, Jan" <jan.sievers@xxxxxxx>]

probably org.eclipse.jdt.junit or one of its dependencies is missing in the eclipse instance used to execute the test.

You can add runtime-only dependencies of tests using e.g. 
 
<plugin>
  <groupId>org.eclipse.tycho</groupId>
  <artifactId>tycho-surefire-plugin</artifactId>
  <configuration>
    <dependencies>
      <dependency>
        <type>p2-installable-unit</type>
        <artifactId>org.eclipse.jdt.junit</artifactId>
      </dependency>
    </dependencies>
  </configuration>
</plugin>

In general, tycho cannot know about any dependencies you require from a project being compiled during test execution.

Subject: [tycho-user] Running eclipse plugin test that depends on an Eclipse library

Hello,

In one of our testing scenarios, we need to test our plugin (for the Scala language) on a project that depends on JUnit. The test fails in Tycho because JUnit is not on the project's classpath, but succeeds in the Eclipse test runner. 

Here's my setup:

 - tycho builds successfully both my plugin and the test fragment
 - it prepares an Eclipse instance populated with the right dependencies and runs my test class
 - my test class copies an existing project recursively into the new/empty workspace
 - my test compiles the test project, and fails because JUnit is not on the classpath

The .classpath looks correct:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.scala-ide.sdt.launching.SCALA_CONTAINER"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/>
        <classpathentry kind="con" path="org.eclipse.jdt.junit.JUNIT_CONTAINER/4"/> 
<classpathentry kind="output" path="bin"/>
</classpath>

(the SCALA_CONTAINER is correctly found).

If I change the junit dependency to point directly to a jar file (instead of the classpath container JUNIT_CONTAINER), the test passes.

What am I doing wrong?

thanks,
iulian
