Question

我有以下课程：

public class SomeClass {

    private int digit;

    public SomeClass(int i){
        digit = i;
    }       
    public int someMethod(int i){
        /*
         * Some work
         */
    }    
    /**
     * Other method
     */
}

当我想用Mockito创建这个类的间谍时，我得到java.lang.NoClassDefFoundError

但是当我将方法改为

时

public int someMethod(){
    // some work
}

所有工作都没有错误。我做错了什么？
我的测试班：

@PrepareForTest ({SomeClass.class})
public class SomeClassTest extends AndroidTestCase {

    private SomeClass someClass = null;

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        // This is necessary on devices in order to avoid bugs with instantiation order
        System.setProperty("dexmaker.dexcache", getContext().getCacheDir().getPath());

        SomeClass localSomeClass = new SomeClass(10);
        someClass = Mockito.spy(localSomeClass);
        Mockito.doReturn(5).when(someClass).someMethod();
    }

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

    public void testCorrectExemption(){
        /**
         * Test code
         */
    }
}

编辑堆栈跟踪，异常

Answer 1

我通过将mockito-core.jar替换为mockito-all.jar

来解决了这个问题

Answer 2

我不认为它与模拟有任何关系。 NoClassDefFoundError错误即将发生，因为您的SomeClass.class在执行期间不在类路径中。把它放在类路径上，错误就会消失。

当我为带参数的方法创建mock时，NoClassDefFoundError
