From source file:org.parancoe.web.test.BaseTest.java

@Override
protected ConfigurableApplicationContext createApplicationContext(String[] locations) {
    FileSystemResourceLoader rl = new FileSystemResourceLoader();
    MockServletContext servletContext = new MockServletContext(rl);
    servletContext.setMinorVersion(4);/*from w  w  w. j a v  a2s. co m*/
    servletContext.registerContext("/test", servletContext);
    servletContext.setServletContextName("/test");
    servletContext.addInitParameter(ContextLoader.CONFIG_LOCATION_PARAM, arrayToString(locations));
    ContextLoader loader = new ContextLoader();
    WebApplicationContext context = loader.initWebApplicationContext(servletContext);
    return (ConfigurableApplicationContext) context;
