How to mock constructor with PowerMockito
提问by Addev
I'm trying to mock a class constructor with PowerMockito for first time, but it doesn't work. My current code is:
我第一次尝试用 PowerMockito 模拟类构造函数，但它不起作用。我目前的代码是：
public class Bar {
public String getText() {
return "Fail";
}
}
public class Foo {
public String getValue(){
Bar bar= new Bar();
return bar.getText();
}
}
@RunWith(PowerMockRunner.class)
@PrepareForTest(Bar.class)
public class FooTest {
private Foo foo;
@Mock
private Bar mockBar;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
PowerMockito.whenNew(Bar.class).withNoArguments().thenReturn(mockBar);
foo= new Foo();
}
@Test
public void testGetValue() throws Exception {
when(mockBar.getText()).thenReturn("Success");
assertEquals("Success",foo.getValue());
}
}
The test fails because the returned value is "Fail". Where is my problem?
测试失败，因为返回值为“Fail”。我的问题在哪里？

Okey, found the answer, you need to call to
好的，找到答案了，你需要打电话给
@PrepareForTest(Foo.class)
instead of
代替
@PrepareForTest(Bar.class)
