我正在使用easymock + powermock编写测试，因此使用powermock的原因是模拟静态方法。

我的测试课看起来像：

import static org.powermock.api.easymock.PowerMock.mockStatic;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.mockito.Mockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PrepareForTest(StaticTest.class)
public class DummyTest {
    @Test
    public void testDummy() {
        mockStatic(StaticTest.class);
        Mockito.when(StaticTest.testMethod()).thenReturn("hello world");
        ........
}

这是我的测试依赖项和版本：

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.10</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-module-junit4</artifactId>
        <version>1.4.12</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-api-easymock</artifactId>
        <version>1.4.12</version>
        <scope>test</scope>
    </dependency>

运行测试，我得到了初始化错误，如下所示：

java.lang.NoClassDefFoundError: net/sf/cglib/proxy/Enhancer

我有一个简单的 android 常量类，如下所示：

public class Consts extends BaseConstants {

    public static final String SCHEME = "http";

    // Tag used to cancel the request
    public static final String TAG_JSON = "json_obj_req";
}

其中没有其他内容，因此应该很容易模拟。我在我的测试用例中调用它：

Mockito.spy(Consts.class); ...这是失败的。以下是测试用例文件：

public class ApplicationTest extends ActivityInstrumentationTestCase2<MainActivity> {

  MainActivity mActivity;

  public ApplicationTest() {
      super(MainActivity.class);
  }

  @Override
  protected void setUp() throws Exception {
      super.setUp();

      setActivityInitialTouchMode(false);

      mActivity = getActivity();
  }

  public void testUrlValid() {
      Mockito.spy(Consts.class);
  }

}

这是测试用例的 logcat 输出：
