Spring-test and ServletContextListener in web.xml

Question

i try to use spring-test(3.2.10) and integration tests with TestNG by this link.

I created RootTest.java

@WebAppConfiguration
@ContextConfiguration("file:src/test/resources/root-context2.xml")
public class ReferenceServiceTest extends AbstractTestNGSpringContextTests {
...

spring context loaded success. But my global variables not instantiated because web.xml ignored. In web.xml i have my own "listener-class"(implementation of ServletContextListener) and "context-param". How i can load web.xml context(and calls all application startup listeners) with spring integration test context?

Answer 1

As stated in the reference manual, the Spring MVC Test Framework...

"loads the actual Spring configuration through the TestContext framework and always uses the DispatcherServlet to process requests thus approximating full integration tests without requiring a running Servlet container."

The key point there is "without ... a Servlet container". Thus web.xml does not come into the picture here. In other words, there is no way for configuration in web.xml to have an affect on integration tests using the Spring MVC Test Framework.

Now, having said that, it is possible to register a Servlet Filter with MockMvc like this:

mockMvcBuilder.addFilters(myServletFilter);

or

mockMvcBuilder.addFilters(myResourceFilter, "/resources/*");

And you can configure context-param entries by adding them manually to the ServletContext (which is actually Spring's MockServletContext) before you execute assertions on MockMvc like this:

wac.getServletContext().setInitParameter(name, value);

But... there is no way to configure a ServletContextListener using Spring MVC Test. If you want to have a listener applied to all of your requests that pass through Spring MVC, as an alternative you could consider implementing a custom HandlerInterceptor or WebRequestInterceptor (see Configuring interceptors in the reference manual).

Try with a MockServletContext

@Before
public void before() {
    MockServletContext mockServletContext = new MockServletContext();
    mockServletContext.setInitParameter("parameterName", "parameterValue");
    new MyListenerClass().contextInitialized(new ServletContextEvent(mockServletContext));
}
