Example Maven module running SWTBot

I wrote this short example to see how I could unit test an SWT application built with Maven, using the SWTBot framework.

The framework is distributed as a set of Eclipse plugins, so the natural choices are:

  • Using Eclipse to run the tests manually. We can't accept this, as we want to run the tests automatically for continuous integration.

  • Using PDE/Ant to run them automatically from a Eclipse instance. Our understanding is that PDE/Ant is rather unwieldy to set up and run, requiring a full-blown Eclipse installation.

  • Using Maven Tycho. This would have been fine, except for the fact that our actual SWT app depends on a lot of pure Maven modules. Automating the generation of the associated OSGi bundles would require too much work.

Our ideal option was to run SWTBot in a pure Maven project, so we repackaged SWTBot and its dependencies (as listed in the OSGi MANIFEST.MF files) as regular Maven artifacts.

This repository is divided into three folders:

  • eclipse-plugin-projects contains the Eclipse projects that we originally wrote and tested inside Eclipse. SayHello is the application itself, and SayHello.tests is a fragment project which tests the application. Our IsolatedShellTest superclass can be reused for any test suite which needs to recreate the main Shell of the application in every test.

  • maven-deps contains a repackaged version of SWTBot 2.0.4 and its dependencies (based on Eclipse Helios 3.6.2), as pure Maven artifacts. If you're not using a repository manager, you can use install.sh to install those dependencies into your local repository.

  • maven-module/sayhello is the mavenized version of the two previous Eclipse projects, using the repackaged SWTBot from above. You should change the <repository> inside pom.xml to the address of your repository manager, if you have one. If you have installed the dependencies through maven-deps/install.sh, you can also simply delete the <repositories> element.

Testing the SWT application is as simple as running the following command from the maven-module/sayhello directory:

mvn test
