[英]How to mock constructor with PowerMockito
I'm trying to mock a class constructor with PowerMockito for first time, but it doesn't work. 我是第一次尝试使用PowerMockito模拟类构造函数,但它不起作用。 My current code is:
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". 测试失败,因为返回值为“Fail”。 Where is my problem?
我的问题在哪里?
Okey, found the answer, you need to call to 哦,找到答案,你需要打电话给
@PrepareForTest(Foo.class)
instead of 代替
@PrepareForTest(Bar.class)
