Unit testing Struts2 actions with Spring

For one of the projects on which I am working, I as looking for a solution to test the Struts2 actions while using the Spring plugin for Struts2.

There is a good article here "http://depressedprogrammer.wordpress.com/2007/06/18/unit-testing-struts-2-actions-spring-junit/", but this solution has one major problem, it tests the action alone, not the action inside the whole Struts2 request process.

So I extended the proposed solution to have a full solution to test the actions inside the Struts2 request process, including the interceptors stack, and here is the result :

/** */public class AbstractActionTest extends TestCase {    /**     */    private final ActionProxyFactory actionProxyFactory;    /**     */    private MockHttpSession session;    /**     * @param configLocations     */    public AbstractActionTest(final String configLocations) {        final MockServletContext servletContext = new MockServletContext();        servletContext.addInitParameter(ContextLoader.CONFIG_LOCATION_PARAM,            configLocations);        final ContextLoader contextLoader = new ContextLoader();        contextLoader.initWebApplicationContext(servletContext);        final Map initParams = new Hashtable();        final Dispatcher dispatcher =            new Dispatcher(servletContext, initParams);        dispatcher.init();        Dispatcher.setInstance(dispatcher);        final Container container = dispatcher.getContainer();        this.actionProxyFactory =            container.getInstance(ActionProxyFactory.class);        this.session = new MockHttpSession();        /*         * When testing with mock services, reinitialize the data between each         * test.         */        // MockData.clear();        // MockData.load();    }    /**     * @param namespace     * @param name     * @param parameters     * @return a string representing the logical result of the execution.     * @throws Exception     */    @SuppressWarnings("unchecked")    protected String executeAction(final String namespace, final String name,    final Map parameters) throws Exception {        final ActionProxy actionProxy =            this.actionProxyFactory.createActionProxy(namespace, name, null,                null, true, false);        final ActionInvocation actionInvocation = actionProxy.getInvocation();        final ActionContext actionContext =            actionInvocation.getInvocationContext();        actionContext.setParameters(parameters);        ActionContext.setContext(actionContext);        final MockHttpServletRequest request = new MockHttpServletRequest();        request.setSession(this.session);        final MockHttpServletResponse response = new MockHttpServletResponse();        ServletActionContext.setRequest(request);        ServletActionContext.setResponse(response);        final String result = actionProxy.execute();        // In case the session has been inactivated, we need to reassociate it.        this.session = (MockHttpSession) request.getSession(true);        return result;    }    /**     * Find a value by evaluating the given expression against the stack in the     * default search order.     *      * @param expr     * @return the result of evaluating the expression     */    protected Object findValueStackValue(final String expr) {        final ActionContext actionContext = ActionContext.getContext();        final ValueStack valueStack = actionContext.getValueStack();        return valueStack.findValue(expr);    }    /**     * Returns the object bound with the specified name in this session, or null     * if no object is bound under the name.     *      * @param name     * @return the object with the specified name     */    protected Object getSessionValue(final String name) {        return this.session.getAttribute(name);    }    /**     * @param name     * @param value     */    protected void setSessionValue(final String name, final Object value) {        this.session.setAttribute(name, value);    }}

Cimballi a dit…: Hey Arindam, here is an example of how to test a Struts2 action using the above mentioned class :

/**
*/
public class XxxActionTest extends AbstractActionTest {

/**
*/
private static final String ACTION_NAME = "Xxx";

/**
*/
public XxxActionTest() {
super(CONFIG_LOCATIONS);
}

/**
* @throws Exception
*/
@Test
public void testExecute() throws Exception {
final Map<String, Object> parameters = new Hashtable<String, Object>();
parameters.put("xxx", "xxx");

final String result =
super.executeAction(ACTION_NAMESPACE, ACTION_NAME, parameters);
assertEquals(Action.SUCCESS, result);
assertNotNull(super
.getSessionValue(XXX));
}
}
