java - JUnit 测试方法未执行

Question

我有一个 DateAdapter 类，其中通过 2 种方法 mrashall 和 unmarshall 将日期类型编码为字符串类型并将字符串数据类型解码为日期类型。所以我的测试方法没有运行。

public class DateAdapter extends XmlAdapter<String, LocalDate> {

private static final String FORMAT = "yyyy-MM-dd";

/**
 * Java Type => XML
 * 
 * @param date unmappable Java object (date)
 * @return desired XML representation
 * @throws Exception
 */
public String marshal(LocalDate date) throws Exception {
    if (date == null) {
        return null;
    }

    return date.toString(FORMAT);
}

/**
 * String Type => Java Type
 * 
 * @param dateString String needs to parse into java type
 * @return desired Java Type representation
 * @throws Exception
 */

@Override
public LocalDate unmarshal(String dateString) throws Exception {

    if (StringUtils.isNotBlank(dateString)) {

        DateTimeFormatter formatter = DateTimeFormat.forPattern(FORMAT);  
        DateTime dateTime = formatter.parseDateTime(dateString);  

        return dateTime.toLocalDate();            
    }
        return null;
    }

}

我正在使用 Junit、testNG、maven 2.2 和 eclipse Juno。右键单击测试用例不会执行测试方法。

public class DateAdapterTest {
        /* Date adapter is a class to marshall date type into String and unmarshall  
         viseversa.
        */

        DateAdapter dateAdapter;

    private static final String DATE_FORMAT = "2014-01-01";
    private static final LocalDate DATE = new LocalDate(2014, 01, 01);

    @BeforeClass
    public void setUp(){
        dateAdapter = new DateAdapter();
    }

    /*
     * @param Date Date type  
     * @return String String data type date
     * @throw Exception 
   */
    @Test
    public void testMarshal() throws Exception{

        String dateString = dateAdapter.marshal(DATE) ;
        assertEquals(DATE_FORMAT, dateString);      
    }

    /*
     * @param String String data type  
     * @return date LocalDate type date
     * @throw Exception 
    */
    @Test
    public void testUnmarshal() throws Exception{

        LocalDate date = dateAdapter.unmarshal(DATE_FORMAT);
        assertEquals(DATE , date);
}
}

JUnit 测试结果:

首先，您必须决定使用哪个框架:JUnit 或 TestNG。一旦你决定检查你使用的是哪个 @Test 注释。我猜您使用 TestNG 中的 @Test 标记了测试，并尝试使用 JUnit 运行测试。
