當我訪問公共方法時，模擬對象工作正常。但是當我訪問私有方法時它不起作用。我的模擬課：@componentpublic class Test{public List<String> list(){ // some function}}我的主要課程：@componentpublic class Test2{private string method(String method){//here where i have to use mock object//some function}}我的測試用例：public class JunitTestCases{@MockTest test;@Autowired@InjectMocksTest2 test2public void Oncall{Test2 test=new Test2();Method method=Test2.class.getDeclaredMethod("method",String.class);method.setAccessible(true);method.invoke(test, "data");}}我收到以下錯誤。java.lang.reflect.InvocationTargetExceptionat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at com.TestCases.method(TestClass.java:198)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50)at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12)at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47)at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17)有什么建議嗎？我怎樣才能讓它工作？

在調用方法中，您使用string.class[paramter]而不是 Class[][parameterArray]。
無需為 Test2.class 創(chuàng)建另一個對象，您已使用 @injectMocks 只需使用調用方法中的變量即可。
public class JunitTestCases{
@Mock
Test test;
@InjectMocks
Test2 test2;
@Test
public void Oncall{
MockitoAnnotations.initMocks(this);
Class<?>[] params = new Class<?>[]{String.class};
Method method=Test2.class.getDeclaredMethod("method",params);
method.setAccessible(true);
method.invoke(test2, "data");
}
}

寫作測試演示課程
public class PowerMockDemo {
public Point callPrivateMethod() {
return privateMethod(new Point(1, 1));
}
private Point privateMethod(Point point) {
return new Point(point.getX() + 1, point.getY() + 1);
}
}
演示類的測試類
@RunWith(PowerMockRunner.class)
@PrepareForTest(PowerMockDemo.class)
public class PowerMockDemoTest {
private PowerMockDemo powerMockDemoSpy;
@Before
public void setUp() {
powerMockDemoSpy = PowerMockito.spy(new PowerMockDemo());
}
@Test
public void testMockPrivateMethod() throws Exception {
Point mockPoint = mock(Point.class);
PowerMockito.doReturn(mockPoint)
.when(powerMockDemoSpy, "privateMethod", anyObject());
Point actualMockPoint = powerMockDemoSpy.callPrivateMethod();
assertThat(actualMockPoint, is(mockPoint));
}
}
