java - 有没有办法模拟 Portal？

Question

我正在尝试设置单元测试。我正在使用 Struts2 和 Liferay 6.1。

我收到以下错误

java.lang.NullPointerException
at com.liferay.portal.util.PortalUtil.getCompany(PortalUtil.java:305)
at com.mycomp.portlet.action.BasePortletAction.setupSiteAgent(BasePortletAction.java:1169)

这是因为 PortalUtil.getPortal() 返回 null。有什么办法可以创建一个模拟门户吗？没有 MockPortal 类。我找到了名为 MockPortalContext 的东西，但我不确定如何使用它。

这是我到目前为止的代码

BaseTestCase.java

public abstract class BaseTestCase extends TestCase {
private Dispatcher dispatcher;
protected ActionProxy proxy;
private static MockServletContext servletContext;
private MockHttpServletRequest request;
private MockHttpServletResponse response;

public BaseTestCase(String name) {
    super(name);
}

@SuppressWarnings("unchecked")
protected <T>T createAction(Class<T> theClass, String namespace, String actionName, String methodName, HashMap<String, Object> actionContextMap, HashMap<String, Object> parameterMap) throws Exception {

    proxy = dispatcher.getContainer().getInstance(ActionProxyFactory.class).createActionProxy(namespace, actionName, methodName, new HashMap<String, Object>(), true, true);

    for (String key : actionContextMap.keySet()) {
        proxy.getInvocation().getInvocationContext().put(key, actionContextMap.get(key));
    }
    proxy.getInvocation().getInvocationContext().setParameters(parameterMap);
    proxy.setExecuteResult(true);

    ServletActionContext.setContext(proxy.getInvocation().getInvocationContext());
    request = new MockHttpServletRequest();
    response = new MockHttpServletResponse();
    ServletActionContext.setRequest(request);
    ServletActionContext.setResponse(response);
    ServletActionContext.setServletContext(servletContext);

    return (T) proxy.getAction();
}

protected void setUp() throws Exception {
    final String[] config = new String[]{"struts.xml", "mockApplicationContext.xml"};
    servletContext = new MockServletContext();
    final XmlWebApplicationContext appContext = new XmlWebApplicationContext();
    appContext.setServletContext(servletContext);
    appContext.setConfigLocations(config);
    appContext.refresh();
    servletContext.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, appContext);

    HashMap<String, String> params = new HashMap<String, String>();
    params.put("actionPackages", "com.mycomp.portlet.action");
    dispatcher = new Dispatcher(servletContext, params);
    dispatcher.init();
    Dispatcher.setInstance(dispatcher);
}
}

ActionTest.java

public class ActionTest extends BaseTestCase {
private Map<String, Object> contextMap;
private Map<String, Object> parameterMap;
private MockPortletRequest portletRequest;
private final String REQUEST_LOCALE = "request_locale"; 

public ActionTest(String name) {
    super(name);
}

public void testShowDetail() throws Exception {
    init();
    parameterMap = new HashMap<String, Object>();
    parameterMap.put(REQUEST_LOCALE, "en_GB");
    @SuppressWarnings("unused")
    PortletAction lspa = createAction(PortletAction.class, 
                                            "/view",
                                            "myAction",
                                            "myAction",
                                            (HashMap<String, Object>)contextMap,
                                            (HashMap<String, Object>)parameterMap);

    String result = proxy.execute();
    System.out.println(result);
}

private void init() {
    portletRequest = new MockPortletRequest();
    contextMap = new HashMap<String, Object>();
    contextMap.put(PortletActionConstants.REQUEST, portletRequest);
}

}

Spring documentation说使用无参数构造函数创建一个 MockPortletRequst() 会使用默认的 MockPortletContext 和 MockPortalContext 创建它，所以我不知道为什么它是 null .

使用Powermock或jMockit模拟静态方法调用PortalUtil.getPortal()
