我写了一批实体。 我现在试图检验他们。 我与一个非常相似的实体存在问题,但当我清理大楼时,这个问题突然消失。 然后,我开始撰写“SetaMap”的类似试验,然后是......。 我有99.9999%确信,我只坚持100 SetMaps。 然而,我的检验表明,在以下法典中有101个问题。

1. I feel like these tests suck. Can someone give me some pointers on unit testing Entity classes? what exactly should I be testing for? merely existing after I persist them?

2. 因此,为什么有101个标准标准回到了我下面的测试方法中。 ......为什么......

3. I get this error everytime I compile:

   89 persistence-test WARN [main] openjpa.Runtime - The persistence unit "persistence-test" was found multiple times in the following resources "[file:/home/matt/Code/vox/vox-lib/vox-lib-common/vox-entity/target/classes/META-INF/persistence.xml, file:/home/matt/Code/vox/vox-lib/vox-lib-common/vox-entity/src/main/resources/META-INF/persistence.xml]", but persistence unit names should be unique. The first persistence unit matching the provided name in "file:/home/matt/Code/vox/vox-lib/vox-lib-common/vox-entity/target/classes/META-INF/persistence.xml" is being used. 202 persistence-test INFO [main] openjpa.Runtime - Starting OpenJPA 2.1.1 448 persistence-test INFO [main] openjpa.jdbc.JDBC - Using dictionary class "org.apache.openjpa.jdbc.sql.DerbyDictionary".

there is definitely only one persistence.xml in my src/main/resources/META-INF folder. I am using maven. Is it possible maven is copying something somewhere?

public class SetMapTest {

        q = em.createQuery(qString);
        qr = q.getResultList();
        assertEquals(count, qr.size());  // this is the method that fails
        // it claims there are 101 SetMaps in the P.C.


        for (int i = 0; i < 1; i++) {
            String qt = "SELECT x FROM SetMap x WHERE x.title =  title:" + i + " ";
            q = em.createQuery(qt);
            qr = q.getResultList();
            assertEquals(1, qr.size());
            // i played around with this a little bit. It seems there are two SetMaps
            // whose titles are "title:0" I can t figure out how that is....
        }
    }
}

我的一些实用方法:

public static PhraseMap getNumberedPhraseMap(int pos){
        PhraseMap phraseMap = new PhraseMap();
        phraseMap.setTitle("title:" + pos);
        return phraseMap;
 }

public static ArrayList<PhraseMap> getNumberedPhraseMapList(int count){
        ArrayList<PhraseMap> phraseMaps = new ArrayList<PhraseMap>();
        for(int i = 0; i < count; i++){
            PhraseMap phraseMap = getNumberedPhraseMap(i);
            phraseMaps.add(phraseMap);
        }
        return phraseMaps;
}
