java - mock-maker-inline 使测试失败，并在非最终非静态类上“传递给 Mockito.mockingDetails() 的 NotAMockException 参数应该是一个模拟”

问题描述

我有一个 JUnit 测试，其中有 5 个模拟，其中一个模拟类是最终的，我启用了 mock-maker-inline 来克服这个问题，现在测试通过了，但在测试执行结束时，我也得到 NotAMockException：

org.mockito.exceptions.misusing.NotAMockException: Argument passed to Mockito.mockingDetails() should be a mock, but is an instance of class ...Locals!

模拟非常简单：

    @Mock
    private Locals locals; //class

    @Mock
    private Globals globals; // class

    @Mock
    private Cache cache; // interface

    @Mock
    private Reminds reminds; // final class

    @Mock
    private Employeereminds employeereminds; // class

...然后是几个 when().thenReturn() 设置以使其协同工作

在测试期间，模拟看起来像这样：

locals = {Locals@3233} 
globals = {Globals@3234} 
cache = {Cache$MockitoMock$665734991@3237} "cache"
reminds = {Reminds@3235} 
employeereminds = {Employeereminds@3236}

我正在使用 Mockito 2.25.0 也尝试过 2.28.2 但没有区别。

我可以重构我的测试来测试最终课程的内容，但我更喜欢我的测试被隔离。我也可以使用 powermock，但也看到过 powermock 报告的类似问题。

有没有人偶然发现这样的问题并找到了一个不错的解决方法？

编辑：我做了更多调查，我删除Locals了 Mock 并在模拟时遇到了同样的错误Globals。然后我删除Globals了模拟并得到（！？）以下异常（@ v2.28.2）：

org.mockito.exceptions.misusing.NotAMockException: Argument passed to Mockito.mockingDetails() should be a mock, but is an instance of class Cache$MockitoMock$149288076!

解决方案

好的，我发现了问题：我正在调用

Mockito.framework().clearInlineMocks();

在@After注释调用的代码中，但正确的方法是在@AfterClass注释调用的代码中执行此操作，否则在清除模拟后运行 Mockito 自己的验证。
