我有一个类，它有一个私有方法，并在其主体中调用另一个私有方法。所以我想调用第一个私有方法并模拟第二个。这是一个例子：
public class ClassWithPrivateMethod {
private int count;
public ClassWithPrivateMethod() {
}
private void countDown() {
while (isDecrementable())
count--;
}
private boolean isDecrementable() {
throw new IllegalArgumentException();
// if (count > 0) return true;
// return false;
}
}
和测试类：
@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithPrivateMethodTest.class)
public class ClassWithPrivateMethodTest {
private int count;
private ClassWithPrivateMethod classWithPrivateMethod;
@Before
public void setUp() throws Exception {
count = 3;
classWithPrivateMethod = PowerMockito.spy(new ClassWithPrivateMethod());
}
@Test
public void countDown() throws Exception {
Whitebox.setInternalState(classWithPrivateMethod, "count", count);
PowerMockito.doReturn(true, true, false).when(classWithPrivateMethod, "isDecrementable");
Whitebox.invokeMethod(classWithPrivateMethod, "countDown");
int count = Whitebox.getInternalState(classWithPrivateMethod, "count");
assertEquals(1, count);
PowerMockito.verifyPrivate(classWithPrivateMethod, times(3)).invoke("isDecrementable");
}
}
我通过调用第一个私有方法Whitebox.invokeMethod(classWithPrivateMethod, "countDown");并像这样嘲笑第二个，PowerMockito.doReturn(true, true, false).when(classWithPrivateMethod, "isDecrementable");。如你所见isDecrementable方法应该返回true, true, false调用时的值，但 PowerMockito 正在调用真正的方法。
我正在使用这些依赖项：
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<dependency>
<groupId>org.powermock</groupId>

<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>1.10.19</version>
</dependency>
我的测试有什么问题吗？
