如何解决Java assertEquals 导致 JUnit 测试失败
我正在 Netbeans 中处理一个 java jdbcTemplate 项目，但我无法弄清楚我的 equals 和 hashcode 方法覆盖了我的 Dao 的 assertEquals 测试有什么问题。我被告知我需要对对象进行“深度比较”，但从我所见，我的代码已经在这样做了。以下是我涉及这个问题的不同课程
这是我的 Organization.class：
public class Organization {
private int orgId;
private String orgName;
private String orgDescription;
private String orgEmail;
private String orgPhone;
private Location orgLocation;
public int getOrgId() {
return orgId;
}
public void setOrgId(int orgId) {
this.orgId = orgId;
}
public String getOrgName() {
return orgName;
}
public void setOrgName(String orgName) {
this.orgName = orgName;
}
public String getOrgDescription() {
return orgDescription;
}
public void setOrgDescription(String orgDescription) {
this.orgDescription = orgDescription;
}
public String getOrgEmail() {
return orgEmail;
}
public void setOrgEmail(String orgEmail) {
this.orgEmail = orgEmail;
}
public String getOrgPhone() {
return orgPhone;
}
public void setOrgPhone(String orgPhone) {
this.orgPhone = orgPhone;
}
public Location getOrgLocation() {
return orgLocation;
}
public void setOrgLocation(Location orgLocation) {
this.orgLocation = orgLocation;
}
@Override
public int hashCode() {
int hash = 7;
hash = 67 * hash + this.orgId;
hash = 67 * hash + Objects.hashCode(this.orgName);
hash = 67 * hash + Objects.hashCode(this.orgDescription);
hash = 67 * hash + Objects.hashCode(this.orgEmail);
hash = 67 * hash + Objects.hashCode(this.orgPhone);
hash = 67 * hash + Objects.hashCode(this.orgLocation);
return hash;
}
@Override
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final Organization other = (Organization) obj;
if (this.orgId != other.orgId) {
return false;
}
if (!Objects.equals(this.orgName,other.orgName)) {
return false;
}
if (!Objects.equals(this.orgDescription,other.orgDescription)) {
return false;
}
if (!Objects.equals(this.orgEmail,other.orgEmail)) {
return false;
}
if (!Objects.equals(this.orgPhone,other.orgPhone)) {
return false;
}
if (!Objects.equals(this.orgLocation,other.orgLocation)) {
return false;
}
return true;
}
}
这是我的组织道实现：
public class OrgDaoDBImpl implements OrgDao{
private JdbcTemplate jdbcTemplate;
public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
this.jdbcTemplate = jdbcTemplate;
}
//ORGANIZATIONS - PREPARED STATEMENTS
private static final String SQL_INSERT_ORGANIZATION
= "insert into `organization` (org_name,org_description,org_email,"
+ "org_phone,location_id) "
+ "values (?,?,?)";
private static final String SQL_DELETE_ORGANIZATION
= "delete from `organization` where org_id = ?";
private static final String SQL_UPDATE_ORGANIZATION
= "update `organization` set org_name = ?,org_description = ?,org_email = ?,"
+ "org_phone = ?,location_id = ? "
+ "where org_id = ?";
private static final String SQL_SELECT_ORGANIZATION
= "select * from `organization` where org_id = ?";
private static final String SQL_SELECT_ALL_ORGANIZATIONS
= "select * from `organization`";
private static final String SQL_SELECT_LOCATION_BY_ORG_ID
= "select l.location_id,l.loc_name,l.loc_street_address,"
+ "l.loc_city,l.loc_state,l.loc_zip_code,l.loc_lat,l.loc_long "
+ "from location l "
+ "join organization o on l.location_id = o.location_id "
+ "where o.org_id = ?";
@Override
@Transactional(propagation = Propagation.REQUIRED,readOnly = false)
public void addOrganization(Organization organization) {
jdbcTemplate.update(SQL_INSERT_ORGANIZATION,organization.getOrgName(),organization.getOrgDescription(),organization.getOrgPhone(),organization.getOrgEmail(),organization.getOrgLocation().getLocationId());
organization.setOrgId(
jdbcTemplate.queryForObject("select LAST_INSERT_ID()",Integer.class));
}
@Override
public void deleteOrganization(int organizationId) {
jdbcTemplate.update(SQL_DELETE_ORGANIZATION,organizationId);
}
@Override
public void updateOrganization(Organization organization) {
jdbcTemplate.update(SQL_UPDATE_ORGANIZATION,organization.getOrgLocation().getLocationId());
}
@Override
public Organization getOrganizationById(int id) {
try {
Organization org = jdbcTemplate.queryForObject(SQL_SELECT_ORGANIZATION,new OrgMapper(),id);
org.setOrgLocation(findLocationForOrganization(org));
return org;
} catch (EmptyResultDataAccessException ex) {
return null;
}
}
@Override
public List<Organization> getAllOrganizations() {
return jdbcTemplate.query(SQL_SELECT_ALL_ORGANIZATIONS,new OrgMapper());
}
@Override
public List<Organization> getAllOrgsBySupeId(int supeId) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods,choose Tools | Templates.
}
/////////////////////
//*HELPER METHODS*//

//FIND Location associated with an organization
private Location findLocationForOrganization(Organization org) {
return jdbcTemplate.queryForObject(SQL_SELECT_LOCATION_BY_ORG_ID,new LocationMapper(),org.getOrgId());
}
//ASSOCIATE the location with the org entry
private List<Organization>associateLocationWithOrg(List<Organization> orgList) {

// add the Location to current Org
currentOrg.setOrgLocation(findLocationForOrganization(currentOrg)); }
return orgList;
}
/////////////

private static final class OrgMapper implements RowMapper<Organization> {
@Override
public Organization mapRow(ResultSet rs,int i) throws SQLException {
Organization org = new Organization();
org.setOrgId(rs.getInt("org_id"));
org.setOrgName(rs.getString("org_name"));
org.setOrgDescription(rs.getString("org_description"));
org.setOrgPhone(rs.getString("org_phone"));
org.setOrgEmail(rs.getString("org_email"));
return org;
}
}
private static class LocationMapper implements RowMapper<Location>{
@Override
public Location mapRow(ResultSet rs,int i) throws SQLException {
Location loc = new Location();
loc.setLocationId(rs.getInt("location_id"));
loc.setLocName(rs.getString("loc_name"));
loc.setLocStreetAddress(rs.getString("loc_street_address"));
loc.setLocCity(rs.getString("loc_city"));
loc.setLocState(rs.getString("loc_state"));
loc.setLocZipCode(rs.getString("loc_zip_code"));
loc.setLocLat(rs.getString("loc_lat"));
loc.setLocLong(rs.getString("loc_long"));
return loc;
}
}
}
My Organization.class 使用 Location 对象来输入额外的位置信息。所以在下面，我首先必须在尝试添加组织之前添加一个位置。目前，添加位置测试成功。
public class SuperSighting_DaoTests {
LocationDao ldao;
OrgDao odao;
PowerDao pdao;
SightingDao sidao;
SupeDao sudao;
public SuperSighting_DaoTests() {
}
@BeforeClass
public static void setUpClass() {
}
@AfterClass
public static void tearDownClass() {
}
@Before
public void setUp() {
ApplicationContext ctx
= new ClassPathXmlApplicationContext("test-applicationContext.xml");
ldao = ctx.getBean("LocationDao",LocationDao.class);
odao = ctx.getBean("OrgDao",OrgDao.class);
pdao = ctx.getBean("PowerDao",PowerDao.class);
sidao = ctx.getBean("SightingDao",SightingDao.class);
sudao = ctx.getBean("SupeDao",SupeDao.class);
// delete all supes
List<Supe> supes = sudao.getAllSupes(); for (Supe currentSupe : supes) {
sudao.deleteSupe(currentSupe.getSupeId());
}
// delete all powers
List<Power> powers = pdao.getAllPowers(); for (Power currentPower : powers) {
pdao.deletePower(currentPower.getPowerId());
}
//delete all organizations
List<Organization> orgs = odao.getAllOrganizations(); for (Organization currentOrg : orgs) {
odao.deleteOrganization(currentOrg.getOrgId());
}
// delete all locations
List<Location> locations = ldao.getAllLocations(); for (Location currentLocation : locations) {
ldao.deleteLocation(currentLocation.getLocationId());
}
// delete all sightings
List<Sighting> sightings = sidao.getAllSightings(); for (Sighting currentSighting : sightings) {
sidao.deleteSighting(currentSighting.getSightingId());
}
}
@Test
public void testAddGetOrganization() {
Location loc = new Location();
loc.setLocName("Legion of Doom");
loc.setLocStreetAddress("127 Taco St.");
loc.setLocCity("Smalltown");
loc.setLocState("MA");
loc.setLocZipCode("19698");
loc.setLocLat("39.16567925978815");
loc.setLocLong("-75.59452746539126");
ldao.addLocation(loc);
Organization org = new Organization();
org.setOrgName("Legion of Doom");
org.setOrgDescription("evil organization");
org.setOrgPhone("333-444-5678");
org.setOrgEmail("lod@evil.org");
org.setOrgLocation(loc);
odao.addOrganization(org);
Organization fromDao = odao.getOrganizationById(org.getOrgId());
fromDao.toString();
assertEquals(fromDao,org);
}
当测试完成时，我可以看到比较的项目完全相同，但测试失败并给我这个错误：
测试运行：8，失败：1，错误：0，跳过：0，经过的时间：2.931 秒
以下图片显示了被比较的两个对象（'org' 和 'fromDao'）的字段值：two object being compared
我真的不确定从哪里开始，因为我的最终目标依赖于测试的通过。我已经多次浏览代码，除了重写整个程序之外，我不知道该怎么做。任何建议表示赞赏，因为我仍然是新手！谢谢！
解决方法
已删除：完全错误 - 应该更仔细地检查屏幕截图
,我想删除这个问题，但我不能。 -感谢您的快速回复！
我以某种方式解决了这个问题......实际上，我的手机和电子邮件正在检索 - 您可以在屏幕截图中看到这一点......经过数小时的凝视后很容易错过。
我检查了所有代码并切换了顺序以匹配数据库，现在我的测试都是绿色的。
再次感谢！
