使用 SpringExtension.beforeAll 时 @BeforeAll 的 AbstractMethodError

Question

当尝试使用 Junit 运行我的 Spring Boot 应用程序集成测试时，我收到以下错误，与 @BeforeAll 标记和 @AfterAll 标记不允许使用有关。

我正在学习本教程，但由于 Intellij 没有正确选择 Jupiter runner，因此需要向我的 POM 添加一些内容： https://info.michael-simons.eu/2018/06/18/maven-use-junit-5-with-spring-boot-for-unit-and-integration-tests/

@SpringBootTest
public class GameIntegrationTests {

    @Test
    public void test() {

    }

您正在使用该版本的 Spring Boot 不支持的 JUnit 5 M4（即里程碑版本 4）。

您应该将 JUnit Platform 1.1.1 和 JUnit Jupiter 5.1.1 或更高版本与 Spring Boot 2.0.3 一起使用。

确保您还使用JUnit 5.1.1 User Guide 中记录的 Maven Surefire 插件的版本 2.19.1。
