java - org.powermock.reflect.exceptions.FieldNotFoundException

问题描述

美好的一天，我有 2 种方法的课程：首先是公共的 GetLeadRequestsList - 我想测试它，其次是私有的 LeadRequestListResponse - 由第一种方法使用。我嘲笑了第二种方法并调用了第一种方法。我的测试代码在这里。当我运行 testGetLeadRequestsList 时，我
发现了 org.powermock.reflect.exceptions.FieldNotFoundException：在 org.mockito.Mockito 的类层次结构中找不到类型为“org.mockito.internal.progress.MockingProgress”的静态字段。

            assertEquals(expect, result,"GetLeadRequestsList isn't correct.");
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}

也许，任何人都知道如何检查错误。提前致谢

解决方案

我想您使用的 mockito-core 和 powermock-api-mockito 版本不正确。因为如果使用这些库的不兼容版本，可能会出现 FieldNotFoundException。请使用支持版本图表 - https://github.com/powermock/powermock/wiki/Mockito#supported-versions

所以你需要检查你的版本并更正它。

你也应该做接下来的事情：

  1. 在 LeadRequestsControllerImplTest 之前添加 @RunWith(PowerMockRunner.class) 和 @PrepareForTest(LeadRequestsControllerImpl.class)
  2. 从 TestNG @BeforeMethod 更改为 JUnit 注释（例如 @BeforeClass），因为你不能混合它。
