Wicket 测试 - AnnotApplicationContextMock - 没有应用程序附加到当前线程主线程

Question

我已经为一个小型 Web 应用程序编写了几个测试，但是当我尝试运行使用 WicketTester 的页面特定测试时，出现错误。

Google 将我发送到 Apache Wicket 的邮件列表，其中用户遇到了相同的异常。他/她说问题是 AnnotApplicationContextMock 在 Wicket 应用程序之前初始化。我也粘贴了我的 WicketApplication 类。

你们中有人以前处理过这个错误吗？我已经粘贴了下面的异常和类。

我的页面特定测试类：

package com.upbeat.shoutbox.web;

import com.upbeat.shoutbox.services.ShoutService;
import com.upbeat.shoutbox.web.pages.ViewShoutsPage;

public class TestViewShoutsPage extends AbstractIntegrationTest {
    @SpringBeanByType
    private ShoutService svc;

    @SpringBeanByType
    private ShoutItemDao dao;

    protected WicketTester tester;

    @Before
    public void setUp() {
        final AnnotApplicationContextMock appctx = new AnnotApplicationContextMock();

        appctx.putBean("ShoutItemDao", dao);
        appctx.putBean("ShoutService", svc);

        tester = new WicketTester(new WicketApplication() {
            @Override
            protected IComponentInstantiationListener getSpringComponentInjector(WebApplication app) {
                return new SpringComponentInjector(app, appctx, false);
            }
        });
    }

    @Test
    public void testRenderPage() {
        tester.startPage(ViewShoutsPage.class);
        tester.assertRenderedPage(ViewShoutsPage.class);
        FormTester ft = tester.newFormTester("addShoutForm");
        ft.setValue("nickname", "test-nickname");
        ft.setValue("content", "a whole lot of content");
        ft.submit();
        tester.assertRenderedPage(ViewShoutsPage.class);
        tester.assertContains("test-nickname");
        tester.assertContains("a whole lot of content");    
    }
}

AbstractIntegrationTest：

package com.upbeat.shoutbox.integrations;

import org.springframework.context.ApplicationContext;
import org.unitils.UnitilsJUnit4;
import org.unitils.spring.annotation.SpringApplicationContext;

@SpringApplicationContext({"/com/upbeat/shoutbox/spring/applicationContext.xml", "applicationContext-test.xml"})
public abstract class AbstractIntegrationTest extends UnitilsJUnit4 {
    private ApplicationContext applicationContext;
}

WicketApplication：

package com.upbeat.shoutbox;

import org.apache.wicket.application.IComponentInstantiationListener;
import org.apache.wicket.protocol.http.WebApplication;
import org.apache.wicket.request.target.coding.IndexedParamUrlCodingStrategy;
import org.apache.wicket.spring.injection.annot.SpringComponentInjector;

import com.upbeat.shoutbox.web.pages.ParamPage;
import com.upbeat.shoutbox.web.pages.VeryNiceExceptionPage;

/**
 * Application object for your web application. If you want to run this application without deploying, run the Start class.
 * 
 * @see com.upbeat.shoutbox.Start#main(String[])
 */
public class WicketApplication extends WebApplication
{    
    /**
     * Constructor
     */
    public WicketApplication()
    {
    }

    /**
     * @see org.apache.wicket.Application#getHomePage()
     */
    public Class getHomePage()
    {
        return HomePage.class;
    }

    @Override
    protected void init() {
        super.init();

        // Enable wicket ajax debug
        getDebugSettings().setAjaxDebugModeEnabled(true);

        addComponentInstantiationListener(getSpringComponentInjector(this));
        // Mount pages
        mountBookmarkablePage("/home", HomePage.class);
        mountBookmarkablePage("/exceptionPage", VeryNiceExceptionPage.class);
        mount(new IndexedParamUrlCodingStrategy("/view_params", ParamPage.class));
    }

    protected IComponentInstantiationListener getSpringComponentInjector(WebApplication app) {
        return new SpringComponentInjector(app);
    }

}

Answer 1

我能够修复它，似乎 Wicket 邮件列表中的用户是对的，我只是直到现在才得到它。

通过将 AnnotApplicationContextMock 的初始化移至 WicketApplication getSpringComponentInjector 方法内部，我能够运行测试。

    @Before
    public void setUp() {
        tester = new WicketTester(new WicketApplication() {
            @Override
            protected IComponentInstantiationListener getSpringComponentInjector(WebApplication app) {
                AnnotApplicationContextMock appctx = new AnnotApplicationContextMock();
                appctx.putBean("shoutItemDao", dao);
                appctx.putBean("shoutService", svc);
                return new SpringComponentInjector(app, appctx, true);
            }
        });

Answer 2

将页面中的（Application application）放入线程池，在池中添加以下条件：
if (!Application.exists()) {
ThreadContext.setApplication(应用程序);
}
