ExceptionInInitializerError với PowerMock và Robolectric

Question

Tôi muốn sử dụng Robolectric với PowerMock, nhưng tôi đang gặp một số sự cố khi chạy chúng. Tôi nghĩ rằng đó là một vấn đề phụ thuộc - ngay bây giờ các lọ của tôi chỉ được quản lý trong Eclipse.

Tôi nhận được một ExceptionInInitializerError theo hai cách. Đầu tiên là thế này:

@RunWith(RobolectricTestRunner.class) 
@PrepareForTest(Logger.class) 
public class Logger_Test { 
    @Mock Config config; 

    @Before 
    public void setUp() { 
     MockitoAnnotations.initMocks(this); 
    }

Nó hoạt động tốt với PowerMockRunner, nhưng ném ngoại lệ cùng với nó như một Rule.

@PrepareForTest(Logger.class) 
    public class Logger_Test { 
    @Rule public PowerMockRule rule = new PowerMockRule(); 
    @Mock Config config; 

    @Before 
    public void setUp() { 
     MockitoAnnotations.initMocks(this); 
    }

Answer 1

Thay vì sử dụng @RunWith(RobolectricTestRunner.class)@RunWith(PowerMockRunner.class)
