我正在尝试测试当我执行我的 HomePresenter 类的方法“onCreate(IHomeView iHomeView)”时调用“setTabs()”。 “SetTabs()”是IHomeView中的一个接口(interface)方法。为了测试它，我使用了 mockito，但是当我调用 homeView.setTabs() 时出现了 illegalArgumentException

我把我的代码放在这里，很简单:

我的简单测试:

import junit.framework.Assert;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;

import static org.fest.assertions.api.Assertions.assertThat;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
import static org.robolectric.util.FragmentTestUtil.startFragment;

@RunWith(RobolectricTestRunner.class) 
public class HomeFragmentTest {

    @Test
    public void testOnCreateHomePresenter() {
       IHomeView homeViewMock = mock(IHomeView.class);

       HomePresenter homePresenter = new HomePresenter();
       homePresenter.onCreate(homeViewMock);

       verify(homeViewMock, times(1)).setTabs();
     }
}

IHomeView.class

public interface IHomeView {

   public void setTabs();

}

HomePresenter.java

public class HomePresenter implements IHomePresenter {

private IHomeView mHomeView;

public void onCreate(IHomeView homeView) {
    mHomeView = homeView;

    mHomeView.setTabs();
}
}

HomeFragment --> 实现 IHomeView

public class HomeFragment extends RoboFragment implements IHomeView {

@Inject
HomePresenter mHomePresenter;
@InjectView(R.id.tv1)
TextView textView;
@InjectView(R.id.progessbar)
SmoothProgressBar progressBar;
@InjectView(R.id.pager)
private ViewPager mViewPager;
@InjectView(R.id.tabs)
private PagerSlidingTabStrip tabs;

private TabAdapter mAdapter;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_home, container,
            false);

    if (rootView == null)
        throw new IllegalStateException("Can't inflate the view");

    return rootView;
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Logger.logWarning("=>onViewCreated()");

    progressBar.setProgressiveStartActivated(true);

    mHomePresenter.onCreate(this);
}


@Override
public void setTabs() {
    mAdapter = new TabAdapter(getChildFragmentManager(), getResources());
    mViewPager.setAdapter(mAdapter);

    int marginBetweenPages = getMarginBetweenPages();
    mViewPager.setPageMargin(marginBetweenPages);
    tabs.setViewPager(mViewPager);
}
}

build.gradle 中的依赖

// ================== TESTING LIBRARIES ======================
androidTestCompile 'junit:junit:4.10'

androidTestCompile 'org.mockito:mockito-core:1.9.5'
androidTestCompile 'com.google.dexmaker:dexmaker:1.0'
androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.0'

此外，我曾尝试对 setTabs() 中的所有方法进行注释，但它不起作用。我正在使用 Mockito 1.9.5 和 Robolectric 2.3。我使用 Android Studio 0.8.1，运行测试的命令是:

./gradlew test

我认为，测试非常简单，但我没有让它工作。 有人可以说我做错了什么吗？

我还包括 gradle 输出:

    java.lang.IllegalArgumentException
    at com.google.dexmaker.mockito.InvocationHandlerAdapter.invoke(InvocationHandlerAdapter.java:49)
    at com.sun.proxy.$Proxy31.setTabs(Unknown Source)
    at com.peerade.ave.presenters.HomePresenter.onCreate(HomePresenter.java:24)
    at com.peerade.ave.tests.HomeFragmentTest.testOnCreateHomePresenter(HomeFragmentTest.java:56)

Gradle Test Executor 1 完成执行测试。

非常感谢!

已修复!

如果您从 androidTestCompile 中删除 dexmaker 和 dexmaker-mockito，它会像魅力一样工作。我在这里找到了解决方案:https://code.google.com/p/dexmaker/issues/detail?id=4

最佳答案

就我而言，将 Mockito 和 Dexmaker 升级到最新版本解决了这个问题: androidTestCompile 'org.mockito:mockito-core:1.10.5' androidTestCompile 'com.crittercism.dexmaker:dexmaker:1.4' androidTestCompile 'com.crittercism.dexmaker:dexmaker-mockito:1.4' androidTestCompile 'com.crittercism.dexmaker:dexmaker-dx:1.4'

关于android - Mockito 的 IllegalArgumentException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24915212/
