如何在Android测试中使用Mockito和dexmaker？

Question

我试图让Mockito(1.9.5 rc1)在我的Android测试中工作(使用Robotium).为了让它在DVM上运行,我将dexmaker.jar和dexmaker-mockito.jar(v 0.9)放在test-project的类路径中.

在Eclipse中作为Android JUnit测试进行测试后运行:

package com.stampay.pos.test;

import roboguice.RoboGuice;
import android.app.Application;

import com.jayway.android.robotium.solo.Solo;
import com.stampay.pos.activities.HomeActivity;
import com.stampay.pos.model.Consumer;
import com.stampay.pos.util.ScannerAndroid;

import static org.mockito.Mockito.*;

public class HomeActivityTest extends ActivityTest<HomeActivity> {
    private Solo solo;
    Application app;

    public HomeActivityTest() {
        super(HomeActivity.class);

    }

    @Override
    public void setUp() throws Exception {
        solo = new Solo(getInstrumentation(), getActivity());
    }

    @Override
    public void tearDown() throws Exception {
        solo.finishOpenedActivities();
        RoboGuice.util.reset();
    }

    public void testScan() throws Exception {

        ScannerAndroid scanner = (ScannerAndroid) getActivity().getScannerHelper();

        Consumer mockConsumer = mock(Consumer.class);

        //scanner.generateResult("consumer1");
    }
}

我得到以下堆栈跟踪:

有什么建议？http://code.google.com/p/dexmaker/和http://code.google.com/p/mockito/wiki/ReleaseNotes不提供任何有用的信息.

类似的问题似乎在这里报道:http://www.paulbutcher.com/2012/05/mockito-on-android-step-by-step/#comment-65955

更新:使用来自https://github.com/paulbutcher/mockito-on-android/tree/master/WarehouseManagerTest/libs的.jar文件都可以顺利运行,尽管他使用基于1.9.1的Mockito过时快照

我在尝试使用mockito 1.9.5-rc1时遇到了同样的问题。

dexmaker 页面指出您需要 1.9.5+为此，显然 RC1 并没有削减它。Mockito 1.9.5 似乎几天前刚刚发布，所以它应该很快就会出现在 Maven Central 中。

同时，您可以从 Mockito 的网站下载 1.9.5 zip。如果您使用 Maven，则可以使用mvn install:install-file. 我还通过查看最新的 Mockito 源代码（未发布的 1.9.8）、构建并安装到我的本地 Maven 存储库来实现此功能。
