How to run JUnit Eclipse Plugin tests with JMock?

Question

Hello,

I have Eclipse plug-in and junit tests for it, which are using jMock library.

When I run my test 'as junit', all tests are running correctly. But when I run them 'as JUnit plugin test' I'm getting the following error:

How to fix this? Appreciate any help.

Answer 1

I've fixed it. JMock plugin, which I initially created, was the following:

plugin.xml:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin
id="jmock-2.5.1"
name="JMockClasses Plug-in"
version="1.0.0"
provider-name="">

<runtime>
  <library name="bsh-core-2.0b4.jar">
     <export name="*"/>
  </library>
  <library name="cglib-2.1_3-src.jar">
     <export name="*"/>
  </library>
  ...
  <library name="jmock-2.5.1.jar">
     <export name="*"/>
  </library>      
  <library name="jmock-junit4-2.5.1.jar">
     <export name="*"/>
  </library>
  ...
</runtime>
<requires>
   <import plugin="org.eclipse.core.runtime.compatibility"/>
</requires>


</plugin>

i. e. it was just a library on my classpath. I've changed it to the following: META-INF/MANIFEST.MF:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: JMockPlugin
Bundle-SymbolicName: org.jmock_2.5.1
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: jmock.Activator
Require-Bundle: org.eclipse.ui,
 org.eclipse.core.runtime,
 org.junit4
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Bundle-ActivationPolicy: lazy
Bundle-ClassPath: bsh-core-2.0b4.jar,
 cglib-2.1_3-src.jar,
 cglib-nodep-2.1_3.jar,
 hamcrest-core-1.1.jar,
 hamcrest-library-1.1.jar,
 jmock-2.5.1.jar,
 jmock-junit3-2.5.1.jar,
 jmock-junit4-2.5.1.jar,
 jmock-legacy-2.5.1.jar,
 jmock-script-2.5.1.jar,
 objenesis-1.0.jar

Now Eclipse OSGI classloader is able to load my JMockPlugin and I do not have any problems.
