Use SwingApplication With JUnit Tests

picture_as_pdf

If you want to start a JVx application during a JUnit Test, it's important that you don't call System.exit during the test - otherwise, your unit test will stop.

This example shows how you start an application:

public SwingApplication startApplication()
{
    SwingApplication app = new SwingApplication();
    app.setSystemExitOnDispose(false);
    app.startup(FirstApplication.class.getName(), 
                "/apps/firstapp/application.xml", null); 
 
    long lTime = System.currentTimeMillis();
 
    while ((app.getApplication() == null 
            || !app.getApplication().getLauncher().isVisible())
           && lTime + 60000 > System.currentTimeMillis())
    {
        try
        {
            Thread.sleep(100);
        }
        catch (InterruptedException ie)
        {
            throw new RuntimeException(ie);
        }
    }
 
    IApplication jvxapp = (IApplication)app.getApplication();
 
    if (jvxapp == null)
    {
        Assert.fail("Application was not started!");
    }
 
    return app;
}

If you have problems with config.xml, use following to set the configuration base directory:

@BeforeClass
public static void beforeClassBaseApplicationTest() throws Exception
{
    System.setProperty(IPackageSetup.CONFIG_BASEDIR, new File("").getAbsolutePath());
}
