找不到测试-在裸骨Spring Boot Maven项目上运行jUnit 5测试用例时，测试套件为空

问题描述

所以我们收到了消息

Process finished with exit code 0
Empty test suite.

当尝试在我们的多模块项目上运行Junit5测试用例时，为了测试问题的根源，我决定从头开始尝试一个新项目(我使用的是IntelliJ IDEA 2018.2.4).

When trying to run Junit5 testscases on our multi module project, so for testing the sources of the issue, I decided to try a new project from scratch (I am using IntelliJ IDEA 2018.2.4).

以下简单的项目POM文件出现了相同的问题:

I am getting the same issue with the following simple project POM file:

</project>

我尝试使用/不使用junit-vintage-engine同样的结果.

I tried with/without the junit-vintage-engine same results.

以下是测试类:

package com.org.bu.dep.app.demo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class DemoApplicationTests {

    @Test
    public void contextLoads() {
        Assertions.assertTrue(true);
    }

}

在运行"窗口中，显示为No tests were found.

On the Run window, it says No tests were found.

我尝试了许多变体，例如带/不带@SpringBootTest注释，也尝试了@ExtendWith(SpringExtension.class)，但无济于事.

I tried many variations such as with/without @SpringBootTest annotation, I tried @ExtendWith(SpringExtension.class) as well to no avail.

我已经在Google上搜索了，大多数结果/SackOverflow答案似乎来自2016/2017年，重点是较老版本的IntelliJ，该版本与Junit 5存在问题，似乎没有关系.

I already googled and most results/SackOverflow answers seem to be from 2016/2017 focused on older versions of IntelliJ which had issues with Junit 5, which do not seem to be related.

请问有什么建议吗?如果我们花太多时间将其恢复为4，我非常不希望这样做:)

Please, any advice?If we spend too much time on it will be forced to revert to 4, and I very much do not wish to do that :)

推荐答案

因此，在Spring Boot 2上使用Junit 5的有效方法是以下3种方法:

So, what works for Junit 5 with Spring Boot 2 is the following 3 TOGETHER:

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.3.1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.3.1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-params</artifactId>
    <version>5.3.1</version>
    <scope>test</scope>
</dependency>

通过空项目进行测试和验证.

Tested and verified with empty project.

请注意，@ Michael Legart的答案建议添加

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.22.1</version>
</plugin>

Maven测试(和Jenkins)需要检测和执行测试！

Is needed for maven test (and Jenkins) to detect and execute the tests!
