Re: Writing a unit test that goes through result-types

[Timothy Astle <ti...@caris.com>]

I found an article on how to statically load Tiles to get past the 
container issue.  I found a web site that explained how to initialize 
the tiles container.  See below:

<snip>
    protected void setUp() throws Exception {
        if (applicationContext == null) {
            // this is the first time so initialize Spring context
            servletContext = new MockServletContext();
            servletContext.addInitParameter(
                    ContextLoader.CONFIG_LOCATION_PARAM, CONFIG_LOCATIONS);
            applicationContext = (new ContextLoader())
                    .initWebApplicationContext(servletContext);

            // Struts JSP support servlet (for Freemarker)
            new JspSupportServlet().init(new 
MockServletConfig(servletContext));

            // Below is the fix I needed.

            // Statically configuring tiles since we do not load it from the
            // web.xml for tests.
            servletContext.addInitParameter(
                    BasicTilesContainer.DEFINITIONS_CONFIG,
                    "/WEB-INF/tiles-def-test.xml");
            final StrutsTilesListener tilesListener = new 
StrutsTilesListener();
            final ServletContextEvent event = new ServletContextEvent(
                    servletContext);
            tilesListener.contextInitialized(event);
        }
.....
