java - Surefire 没有接受 Junit 5 测试

Question

我用 JUnit 5 写了一个简单的测试方法:

public class SimlpeTest {
    @Test
    @DisplayName("Some description")
    void methodName() {
        // Testing logic for subject under test
    }
}

但是当我运行 mvn test 时，我得到了:

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running SimlpeTest
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.001 sec

Results :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

不知何故，surefire 无法识别该测试类。我的 pom.xml 看起来像:

<properties>
    <java.version>1.8</java.version>
    <junit.version>5.0.0-SNAPSHOT</junit.version>
</properties>

<dependencies>
    <dependency>

                <source>${java.version}</source>
                <target>${java.version}</target>
            </configuration>
        </plugin>
    </plugins>
</build>

知道如何进行这项工作吗？

maven-surefire-plugin，从今天开始，not have full support of JUnit 5 .在 SUREFIRE-1206 中添加此支持存在一个 Unresolved 问题。 .

因此，您需要使用 custom provider . JUnit 团队已经开发了一个；来自 user guide ，您需要为新 API 添加 junit-platform-surefire-provider 提供程序和 TestEngine 实现:

<build>
  <plugins>        
    <plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <!-- latest version (2.20.1) does not work well with JUnit5 -->
      <version>2.19.1</version>
      <dependencies>
        <dependency>
          <groupId>org.junit.platform</groupId>
          <artifactId>junit-platform-surefire-provider</artifactId>
          <version>1.0.3</version>
        </dependency>
        <dependency>
          <groupId>org.junit.jupiter</groupId>
          <artifactId>junit-jupiter-engine</artifactId>
          <version>5.0.3</version>
        </dependency>
      </dependencies>
    </plugin>
  </plugins>
</build>

另外，请务必声明 junit-jupiter-api 依赖项，其范围为 test:

<dependencies>
  <dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.0.3</version>
    <scope>test</scope>
  </dependency>
</dependencies>
