java - org.mockito.exceptions.base.MockitoException : Please ensure that the type 'UserRestService' has a no-arg constructor

Question

我想为 Rest API 创建 JUnit5 测试。

@Test
public void resetRequest_NAME_AND_EMAIL_MISMATCH() throws Exception {
    when(userRestService.resetRequest(anyString(), anyString())).thenReturn(Boolean.valueOf("test"));

    MvcResult result = mockMvc.perform(post("/users/reset_request")
            .contentType(MediaType.APPLICATION_JSON)
            .content(ResetUserDTO))
            .andExpect(status().isBadRequest())
            .andReturn();

    assertEquals(result.getResponse().getContentAsString(), "NAME_AND_EMAIL_MISMATCH");
}

但是当我运行测试时出现异常

org.mockito.exceptions.base.MockitoException: Unable to initialize @Spy annotated field 'userRestService'.
Please ensure that the type 'UserRestService' has a no-arg constructor.

休息服务代码:GitHub

我尝试添加 @NoArgsConstructor 但我收到警告，变量(UsersService userService、PasswordAdminResetHandler resetHandler 等)未初始化。

你知道我该如何解决这个问题吗？

Answer 1

另一种选择是显式创建 Spy userRestService

@Spy
private UserRestService userRestService = new UserRestService(...);

并使用创建的 Spys 或 Mocks(根据需要)作为参数
