java.lang.IllegalStateException：运行 Junit 测试用例时无法加载 ApplicationContext

【中文标题】java.lang.IllegalStateException：运行 Junit 测试用例时无法加载 ApplicationContext【英文标题】：java.lang.IllegalStateException: Failed to load ApplicationContext while running Junit testcases 【发布时间】：2021-10-06 04:33:22 【问题描述】：已经开发了以下配置的springboot项目：
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.0.RELEASE</version>
<relativePath />
</parent>
对嵌入式 redis 使用以下配置：
<dependency>
<groupId>com.github.kstyrc</groupId>
<artifactId>embedded-redis</artifactId>
<version>0.6</version>
</dependency>
在 controllertest.class 中添加以下注释并使用 mockito 模拟数据库连接。
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = SmsPluginApplication.class)
@WebAppConfiguration
@TestPropertySource(locations = "classpath:application-test2.properties")
如果我们单独运行每个controllertest.class，那么所有的测试用例都通过了。
同时运行所有测试用例时，一个 controllertest.class 低于错误，并且测试用例在其余控制器测试类中通过。

【问题讨论】：
尝试在每个测试类上使用@DirtiesContext 注解，这样它会告诉测试框架关闭并重新创建上下文以供以后测试。 感谢@Bruno Alves，在每个测试类上添加 DirtiesContext 注释后问题已解决。 很好，我添加了答案 【参考方案1】：在每个测试类上使用@DirtiesContext 注解，因此它告诉测试框架关闭并重新创建上下文以供以后的测试使用。
