Run Eclipse Mock Test with Workspace Projects Included

I am writing a small Eclipse plugin and some tests for it. I am running plugin tests by specifying them to run in Headless Mode

. I want to access active Java projects in the workspace in these tests, but when I run them the workspace is empty. I am using the following code to get all Java projects (which works great):

IWorkspaceRoot myWorkspaceRoot = ResourcesPlugin.getWorkspace().getRoot();
for(IProject project : myWorkspaceRoot.getProjects()) {
        if(project.isOpen() && isJavaProject(project)) {
                IJavaProject javaProject = JavaCore.create(project);
                projects.put(project.getName(), javaProject);
        }
}

However, projects are always empty. This is because it Headless Mode

launches a new instance of Eclipse with an empty workspace I guess. My question is, can I somehow specify that the tests should run on the current Eclipse instance? Or can I specify the projects I want to have in the newly created workspace?

I figured out an easy way to set up a test workspace

and wanted to share it with you (even if that means I'm answering my own question):

  • Open Eclipse

    and create a new workspace

    one somewhere on disk
  • Add some sample projects to the new workspace

  • Open the instance Eclipse

    that contains the codePlug-in Test

  • In JUnit Plug-in Test Launch Configuration

    go to the tabMain



Launch configuration for a JUnit Plug-in Test

  1. Indicate workspace

    created in 1) and entered in 2)
  2. Run a test that will start with the specified workspace

    and all of its projects
