Unit testing a Struts Action with Spring integration

[dekker]

Hi,
Are there any resources to help me unit test a Struts action that uses Spring beans? I am using the MockStrutsTestCase to test the action but when I insert the code into the action which retrieves beans from the WebApplicationContext, the Unit test fails. Any help would be much appreciated.

Thanks.

I use the following class when testing my Struts Actions using Struts Testcase

public abstract class BaseDynamicSpringStrutsTest extends MockStrutsTestCase {

  protected StaticWebApplicationContext wac = null;

  /**
   * getter for WebApplicationContext.
   */
  protected StaticWebApplicationContext getWebApplicationContext() {
    return this.wac;
  }

  /**
   * finalize the initialization of the WebApplicationContext.
   */
  public void finalizeSetUp() {
    //bind the WebApplicationContext to the servletContext
    ServletContext sc = getActionServlet().getServletContext();
    wac.setServletContext(sc);

    wac.refresh();
    sc.setAttribute(StaticWebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, this.wac);
  }

	protected void setUp() throws Exception {
    super.setUp();
    setInitParameter("validating", "false");
    wac = new StaticWebApplicationContext();
  }

	protected void tearDown() throws Exception {
	  wac = null;
    super.tearDown();
  }
}

If designed the class to use dynamically created StaticWebApplicationContext :lol:. This way I can register new beans dynamically into the WebApplicationContext. You can easily refactor the class to use a static applicationContext.xml

sample usecase:

public class PasswordActionTestSuite extends BaseDynamicSpringStrutsTest {

  protected void setUp() throws Exception {
    //call parent setUp
    super.setUp();

    //create sample data
    List users = DomainUtils.populateUsers();
    List groups = DomainUtils.populateGroups();

    //retreive Spring WebApplicationContext and register userManager within Spring WebApplicationContext
    MutablePropertyValues pvs = new MutablePropertyValues ();
    pvs.addPropertyValue("users", users);
    pvs.addPropertyValue("groups", groups);

    wac.registerSingleton("userManager", MockUserManager.class, pvs);

    //ask parent class to finalize the setup
    finalizeSetUp();
  }

  protected void tearDown() throws Exception {
    super.tearDown();
  }

  public void testEditForm() {
    //redirect to editPassword
    setRequestPathInfo("/password.do");

    //populate form
    addRequestParameter("action", "editForm");
    addRequestParameter("id", "1");
    addRequestParameter("page", "0");

    //perform the action
    actionPerform();

    //verify that the action forwards to "tiles.passwordForm"
    verifyTilesForward("editForm", "tiles.passwordForm");

    //verify exceptions
    verifyNoActionErrors();
  }
}
