Java 如何使用PowerMockito模拟构造函数
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:Java 如何使用PowerMockito模拟构造函数,java,android,mockito,powermockito,Java,Android,Mockito,Powermockito,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(
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());
}
}
测试失败,因为返回值为“Fail”。我的问题在哪里?好的,找到答案了,你需要打电话给
@PrepareForTest(Foo.class)
而不是
@PrepareForTest(Bar.class)
别忘了这个!
