java - 无法模拟方法响应

Question

我想模拟此 SQL 查询的结果:

   public List<RiskFilters> findRiskFiltersByTerminalIdAndType(int terminal_id, String filter_class) {
        String hql = "....";  
        TypedQuery<RiskFilters> query = entityManager.createQuery(hql, RiskFilters.class)....;
        List<RiskFilters> riskFilters = query.getResultList();
        return riskFilters;
    }

我尝试了这个模型配置:

List<RiskFilters> riskFiltersList = new ArrayList<RiskFilters>();
        riskFiltersList.add(new RiskFilters()); 

        when(riskFilterService.findRiskFiltersByTerminalIdAndType(anyInt(), anyString())).thenReturn(riskFiltersList);

但我在这里得到 NPE:

List<RiskFilters> filter_list = riskFilterService.findRiskFiltersByTerminalIdAndType(11, "BinCountryCheckFilter");

看起来模拟的参数不正确。您知道如何正确实现吗？

Answer 1

我认为需要given(...).willReturn(...)。
