Automating unit tests (junit) for Eclipse Plugin development

Question

I am developing Eclipse plugins, and I need to be able to automate the building and execution of the test suite for each plugin. (Using Junit)

Test are working with

Answer 1

I have just got JUnit testing working as part of the headless build for our RCP application.

I found this article - Automating Eclipse PDE Unit Tests using Ant incredibly helpful. It provides code and approach to get you started. However, a number of things that I discovered:

About the article's code

• there was only one bundle under tests (we have separated out our build process from the code, using Buckminster)
• there was only one test class.
• these were both effectively hardcoded into the build script

About Eclipse PDE

• the uitestapplication requires another testApplication. Using coretestapplication does not.
• as these applications are both in bundles that have dependencies on SWT. This is a deal killer in most circumstances, though not if your build machine is a Windows box. I would love to see these split into non-UI bundles.

I found that the code provided was a good starting point, but had a number of the above assumptions implicit in their implementation.

Having discovered these assumptions, doing the work was relatively straight forward.

Our new and shiny setup

• buckminster builds the bundles.
• target copies the bundles from the target platform, the org.eclipse.pde.runtime and org.eclipse.jdt.junit into a "tester-eclipse-install". This should take care of your Java Result 13 problem.
• find the test fragments from looking at the workspace
• find the fragment host from looking at the manifest
• find the test classes from looking at the project in the workspace.
• register a PDETestListener modified to handle multiple test classes
• invoke the tester-eclipse-install with the multiple test classes.

I also read Build and Test Automation for plug-ins and features but we are not using PDE-Build directly.
