Java @MockClass不工作

我是jmockit新手，正在尝试执行以下在线示例

@MockClass不工作。我的书店的getBookTitle（）方法正在调用orginal类的函数，而不是mock类

书店类：

public class BookStore {

  public String getBookTitle(String isbn){
    return BookStoreService.getBookTitle(isbn);
  }
} 

public class BookStoreService {

  public static String getBookTitle(String isbn){
    return "Random";
  }
}

public class BookStoreTest {

  private static Map<String, String> bookMap = new HashMap<String, String>(2);

  @BeforeClass
  public static void setup() {
    System.out.println("in setup()");
    bookMap.put("0553293354", "Foundation");
    bookMap.put("0836220625", "The Far Side Gallery");
  }

  @MockClass(realClass = BookStoreService.class)
  public static class MockBookstoreService {
    @Mock
    public static String getBookTitle(String isbn) {
        System.out.println("in getBookTitle()");
        if (bookMap.containsKey(isbn)) {
            return bookMap.get(isbn);
        } else {
            return null;
        }
    }
  }

  @Test
  public void testGetBookTitle() throws Exception {
    System.out.println("in testGetBookTitle()");
    final String isbn = "0553293354";
    final String expectedTitle = "Foundation";
    BookStore store = new BookStore();
    String title = store.getBookTitle(isbn);
    System.out.println(title); // This prints "Random" instead of "Foundation"
    Assert.assertEquals(title, expectedTitle);
  }


}

        } else {
            return null;
        }
    }
  }

  @Test
  public void testGetBookTitle() throws Exception {
    System.out.println("in testGetBookTitle()");
    final String isbn = "0553293354";
    final String expectedTitle = "Foundation";
    BookStore store = new BookStore();
    String title = store.getBookTitle(isbn);
    System.out.println(title); // This prints "Random" instead of "Foundation"
    Assert.assertEquals(title, expectedTitle);
  }


}

PS：我正在使用TestNG

使用，您可以这样做：

@BeforeClass
public static void setup() {
    System.out.println("in setup()");
    bookMap.put("0553293354", "Foundation");
    bookMap.put("0836220625", "The Far Side Gallery");

    new MockUp<BookStoreService>() {            
        @Mock
        public String getBookTitle(String isbn) {
            System.out.println("in getBookTitle()");
            if (bookMap.containsKey(isbn)) {
                return bookMap.get(isbn);
            } else {
                return null;
            }
        }
    };
}

@MockClass注释已被删除，您使用哪个版本的jmockit？0.999.2。我知道这是不赞成的。寻找其他替代方案。我建议您开始使用依赖注入。它的好处之一是测试简单得多。在这种特殊情况下，您将把BookStoreService注入BookStore
