使用 SpringExtension.beforeAll 时 @BeforeAll 的 AbstractMethodError

Question

当尝试运行我的 Spring 使用 Junit 启动应用程序集成测试时，我收到以下与不允许使用 @BeforeAll 标签和 @AfterAll 标签有关的错误。

我一直在学习本教程，但需要向我的 POM 添加一些内容，因为 Intellij 没有正确获取 Jupiter 运行ner： https://info.michael-simons.eu/2018/06/18/maven-use-junit-5-with-spring-boot-for-unit-and-integration-tests/

Answer 1

您正在使用 JUnit 5 M4（即里程碑版本 4），Spring Boot 版本不支持它。

您应该改用 JUnit Platform 1.1.1 和 JUnit Jupiter 5.1.1 或更高版本以及 Spring Boot 2.0.3。

确保您还使用 2.19.1 版本的 Maven Surefire 插件，如 JUnit 5.1.1 User Guide.
