Question

我对项目的测试很少，当我执行整个测试类时，我得到No tests were found，但是当我独立测试每个方法时，它们仍然可以工作，并且我发现JUnit5配置不正确。以下是我的罐子和pom.xml

import org.springframework.web.client.HttpClientErrorException;

import static org.junit.jupiter.api.Assertions.assertThrows;

@SpringBootTest
public class ApplicationTests {

    private RestTemplate restTemplate = new RestTemplate();

    private static String BASE_PATH = "http://localhost:8080/exams/";

    @Test
    public void testNotFoundStartExamException() {
        final String url = BASE_PATH + "start/" + null + "/";

        assertThrows(HttpClientErrorException.class, () -> restTemplate.getForEntity(url, String.class));
    }

    @Test
    public void testNotFoundFinishExamException() {
        final String url = BASE_PATH + "finish-page/" + null + "/";

        assertThrows(HttpClientErrorException.NotFound.class, () -> restTemplate.getForEntity(url, String.class));
    }
}

当我使用命令mvn test时，会得到以下结果

[INFO]

根据我需要的文档jupiter-engine, platform-launcher, vintage-engine，我不确定该使用什么，为什么不起作用以及如何使其起作用。我在做什么错了？

问题是由于重复/多个junit依赖关系被添加到pom.xml中引起的。如前所述，您已经拥有spring-boot-starter-test依赖项，其中包括junit Jupiter（5.5.2弹簧启动器的2.2.6.RELEASE）依赖性。您已经手动添加了更高版本的junit（5.6.2）。

如果您查看Junit 5 User Guide，它会指定junit-jupiter-engine in test runtime scope，但是由于您未指定任何作用域，因此会编译作用域，您可以通过检查有效Pom对其进行验证。

简单的修复方法是删除手动添加的junit依赖关系，然后运行mvn clean test。您的测试应该被选中

正确配置JUNIT5以进行测试
