Mockito don not work MockitoSessionLogger DefFoundError

Question

我在Spring项目中的测试运行良好，直到我做了一些事情，在我的WebMvcTest中，MockMvc开始只是为null。在需要模拟存储库的服务测试中，抛出了以下异常：

Answer 1

我建议添加mockito-core依赖项(https://mvnrepository.com/artifact/org.mockito/mockito-core)。

<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>3.7.0</version>
<scope>test</scope>
</dependency>

另一个答案中提到的mockito-all依赖关系上次更新是在2015年。

Answer 2

我遇到了这个问题，我的问题通过在依赖项中添加mockito-core和mockito-junit-jupiter来解决：

</dependency>
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-core</artifactId>
<version>5.1.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-junit-jupiter</artifactId>
<version>4.0.0</version>
<scope>test</scope>
</dependency>

Answer 3

如果这个mockito全部包含在测试资源中，则需要检查您的依赖关系。
