我正在使用maven-java-spring和testNG，在测试流视图之前，一切似乎都很好。我正在尝试解决此异常，我正在寻找，并且我发现了一些不同的版本但我不相信这个答案，让我展示一个例外：

如果有人需要更多信息，我将被征集以显示它（信息）：）
我有更多信息
在测试类中失败的方法是： @Test
public void comprovarCercaBuuida(){
/*Objecte que contindrà l'info de la cerca*/
DeuteBackBean deuteBB;
List<IDeute> respostaDeutesExe = new ArrayList<IDeute>();
List<IDeute> respostaDeutesVol = new ArrayList<IDeute>();
List<IDeute> respostaDeutesTots = new ArrayList<IDeute>();
/*tot els paràmetres del servei s'han de passar com a mockito!!!*/
Mockito.when(serveiGpt.obtenirDeutes(Mockito.eq(CLAU_SUBJECTE_BUIT),Mockito.eq(E_TIPUS_DEUTE_HIS),Mockito.eq(PERIODE_DEUTE_EXE))).thenReturn(respostaDeutesExe);
**startFlow(context)**-->why???
assertCurrentStateEquals(ID_VISTA_FORMULARI_CERCA);
Mockito.when(serveiGpt.obtenirDeutes(Mockito.eq(CLAU_SUBJECTE_BUIT),Mockito.eq(E_TIPUS_DEUTE_HIS),Mockito.eq(PERIODE_DEUTE_VOL))).thenReturn(respostaDeutesVol);
Mockito.when(serveiGpt.obtenirDeutes(Mockito.eq(CLAU_SUBJECTE_BUIT),Mockito.eq(E_TIPUS_DEUTE_HIS),Mockito.eq(PERIODE_DEUTE_TOTS))).thenReturn(respostaDeutesTots);
}

我认为“上下文”是空的？但我不明白..
/ **每个执行的上下文* /
