ID 为“junit-jupiter”的 TestEngine 未能发现测试 - 原因：org.junit.platform.commons.JUnitException：ClassSelector 解析失败

Question

我在运行集成测试时遇到问题。

作为测试的一部分，我习惯于exec-maven-plugin从源代码管理中提取其他项目，然后在本地运行它们，以便我的测试可以使用它来执行。

我的 JUnit Maven 依赖项是：

<plugins>
    <plugin>
        <artifactId>maven-failsafe-plugin</artifactId>
        <version>3.0.0-M5</version>
        <configuration>
            <useModulePath>false</useModulePath>
            <useSystemClassLoader>false</useSystemClassLoader>
            <skipTests>false</skipTests>
            <includes>
                <include>**/*IntegrationTest.java</include>
            </includes>
        </configuration>
        <executions>
            <execution>
                <goals>
                    <goal>integration-test</goal>
                    <goal>verify</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>
...
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <version>2.4.2</version>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.junit.vintage</groupId>
            <artifactId>junit-vintage-engine</artifactId>
        </exclusion>
    </exclusions>
</dependency>

我创建了一个名为的配置文件，integration-test以便我可以选择何时启用集成测试，并且还添加了一个参数来maven-surefire-plugin调用，skipUTs以便我可以跳过单元测试。

运行输出： mvn clean verify -Pintegration-test -DskipUTs=true

测试类大致是：

@SpringBootTest(classes = Application.class,
        webEnvironment = WebEnvironment.RANDOM_PORT)
@Import({SSLRestTemplateConfig.class})
@ExtendWith(SpringExtension.class)
@ActiveProfiles(profiles = {"integration"})
public class IntegrationTest {

    @LocalServerPort
    private int port;

    private final RestTemplate restTemplate;

    @Spy
    private final Service Service;

    private final IQueue<String> queue;

    @Captor
    ArgumentCaptor<String> captor;

    @Autowired
    public IntegrationTest(RestTemplate restTemplate,
                                Service service,
                                HazelcastInstance hazelcastInstance) {
        this.restTemplate = restTemplate;
        this.service = accountingQueueService;
        this.queue = hazelcastInstance.getQueue("queue");
    }

    @BeforeEach
    public void setup() {
        queue.clear();
    }

    @Test
    public void IntegrationTest() throws InterruptedException {
        ...
    }

}

任何帮助将不胜感激。

我也有这个问题。我通过从 IntelliJ / 项目结构 / 库中删除所有 JUnit 库来解决这个问题，然后编译项目，但失败了，让 IntelliJ 通过导入最新版本的 JUnit 来解决这个问题。

我现在使用的是 JUnit 5.9.1

我相信罪魁祸首是 junit-platform-commons，现在版本为 1.9.1

我从这个 JUnit 5 问题中得到了这个想法：https://github.com/junit-team/junit5/issues/2881
