Junit testing and debugging
问题
以下是翻译好的部分：
我正在尝试运行一些 JUnit 测试，但在几个测试中遇到了以下错误。这些是我遇到的错误信息。
[junit] 无法获取属性值
[junit] java.lang.IllegalStateException: 无法获取属性值
[junit] at org.hibernate.validator.ClassValidator.getMemberValue(ClassValidator.java:539)
[junit] at org.hibernate.validator.ClassValidator.getInvalidValues(ClassValidator.java:384)
[junit] at org.hibernate.validator.ClassValidator.getInvalidValues(ClassValidator.java:352)
[junit] at org.hibernate.validator.event.ValidateEventListener.validate(ValidateEventListener.java:139)
[junit] at org.hibernate.validator.event.ValidateEventListener.onPreInsert(ValidateEventListener.java:172)
...
[junit] Caused by: java.lang.NullPointerException
[junit] at org.unavco.pbo.mdm.model.Station.validateProjectDate(Station.java:740)
在错误信息中提到的代码行：
@AssertTrue
private boolean validateProjectDate() {
if (projectDate.before(this.stationProject.getStartDate())) {
return false;
}
if (projectDate.after(this.stationProject.getEndDate())) {
return false;
}
return true;
}
受影响的测试方法：
public void testStationWithFourcharInherit() throws Exception {
String fourCharId = "IOA2";
Date projectDate = new Date();
endTransaction();
Locale locale = createAndSaveLocale(fourCharId);
Site site = createAndSaveSite(locale);
Station station = createAndSaveStation(site, fourCharId);
startNewTransaction();
verifyStationMatches(station, fourCharId);
}
测试中涉及的函数：
protected Station createAndSaveStation(Site site, String fourCharId) {
Station station = new Station();
station.setLongName("MyStationsLongName");
if (fourCharId != null) {
station.setFourCharId(fourCharId);
}
StationType stnType = (StationType) stationDao.getObject(StationType.class, 1L);
station.setStationType(stnType);
StationBuildStatus bldStat = (StationBuildStatus) stationDao.getObject(StationBuildStatus.class, 1L);
station.setStationBuildStatus(bldStat);
Project stnProject = (Project) stationDao.getObject(Project.class, 1L);
station.setStationProject(stnProject);
station.setCommsType(CommsType.CDMA);
station.setLatitude(31.009);
station.setLongitude(128.9930);
station.setElevation(890.3);
station.setStationStatus(StationOperationalStatus.Operable);
station.setLongName("long name");
station.setInstallDate(new Date());
station.setProjectDate(new Date());
site.addStation(station);
stationDao.saveStation(station);
stationDao.validateStartDate(station);
return station;
}
有人知道如何修复这个错误吗？
请注意，由于您要求只返回翻译好的部分，我只提供了代码和文本的翻译，没有添加其他内容。如果您需要进一步的帮助或解释，请随时提问。

Code the last line it is refering to.

}

return true;
}
The test that is affected.
public void testStationWithFourcharInherit() throws Exception {
String fourCharId = "IOA2";
Date projectDate = new Date();
endTransaction();
Locale locale = createAndSaveLocale(fourCharId);
Site site = createAndSaveSite(locale);
Station station = createAndSaveStation(site, fourCharId);
startNewTransaction();
verifyStationMatches(station, fourCharId);
}
The refered function in test.
protected Station createAndSaveStation(Site site, String fourCharId) {
Station station = new Station();
station.setLongName("MyStationsLongName");
if (fourCharId != null) {
station.setFourCharId(fourCharId);
}
StationType stnType = (StationType) stationDao.getObject(StationType.class, 1L);
station.setStationType(stnType);
StationBuildStatus bldStat = (StationBuildStatus) stationDao.getObject(StationBuildStatus.class, 1L);
station.setStationBuildStatus(bldStat);
Project stnProject = (Project) stationDao.getObject(Project.class, 1L);
station.setStationProject(stnProject);
station.setCommsType(CommsType.CDMA);
station.setLatitude(31.009);
station.setLongitude(128.9930);
station.setElevation(890.3);
station.setStationStatus(StationOperationalStatus.Operable);
station.setLongName("long name");
station.setInstallDate(new Date());
station.setProjectDate(new Date());
site.addStation(station);
stationDao.saveStation(station);
stationDao.validateStartDate(station);
return station;
}
Does anyone know how to fix this error?
