Junit 5 找不到测试（Spring Boot）

Question

我通过 Spring Initilizr 创建了一个 Spring Boot 2.2.6 应用程序，其中包括 JUnit 5.6。我正在使用生成的 pom.xml 以及一些额外的依赖项和 Intellij IDEA 2020.1 作为我的 IDE。

我创建了一个非常简单的测试，只是为了看看测试是否有效：

package com.hua.geoutils;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class GeoUtilsTest
{

    @Test
    public void testSplitBoundingBox()
    {
        Assertions.assertEquals(1,1);
    }
}

我执行mvn test spring-boot:run 并在测试生命周期中得到以下信息：

[INFO] --- maven-surefire-plugin:2.22.2:test (default-test) @ atlantis-rest ---
[INFO] 
[INFO] -------------------------------------------------------
[INFO]  T E S T S
[INFO] -------------------------------------------------------
[INFO] 
[INFO] Results:
[INFO] 
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

似乎 maven 甚至没有检测到测试存在，我不明白为什么。关于这里出了什么问题的任何想法？

编辑：

这是我的 pom.xml 文件：

Answer 1

以https://info.michael-simons.eu/2018/06/18/maven-use-junit-5-with-spring-boot-for-unit-and-integration-tests/ 为起点，我建议将 jupiter-engine 添加为显式依赖项：

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <scope>test</scope>
</dependency>

或者，您可以包含junit-jupiter，它是一个聚合组件，而不是junit-jupiter-api。 junit-jupiter 包含 API、引擎和参数化测试组件。

顺便说一句，如果您想使用 Spring Boot 更改 JUnit 的版本，您必须将其添加到您的属性中：

<junit-jupiter.version>5.6.0</junit-jupiter.version>

Answer 2

您同时使用 JUnit4 (Assert) 和 JUnit 5 (@Test)。最初 Maven 会尝试决定需要哪个提供程序来运行测试，并以某种方式选择了 JUnit4。

编辑测试以使用 JUnit5（又名 Juipiter）断言 API。将org.junit.Assert.assertEquals(...) 更改为org.junit.jupiter.api.Assertions.assertEquals(....)

不要忘记在所有测试文件中将出现的 org.junit.Assert.* 更改为 org.junit.jupiter.api.Assertions.*。
