我有一个使用两种测试方法的JUnit 5测试.一个标记为“ slow”,另一个标记为“ fast”.我还用排除标签配置了SureFire插件,使它应该忽略带有“ slow”标签的测试.

我希望通过此设置仅执行带有“ fast”标签的测试,但就我而言,两者都是.看来@Tag注释根本没有任何作用.

这是测试类：

package junit5;

import org.junit.jupiter.api.Tag;
import org.junit.jupiter.api.Test;

class TaggingTest {

    @Tag("fast")
    @Test
    void fast() {
        System.out.println("*** fast ***");
    }

    @Tag("slow")
    @Test
    void slow() {
        System.out.println("*** slow ***");
    }

}

这是我的pom.xml：

当我运行mvn test时,我得到以下输出：

如您所见,两个测试用例都已运行.

据我了解的文档,我已经正确设置了所有内容.我想念什么？

解决方法:

此问题是由在JDK 9上运行的maven-surefire-plugin中的错误引起的：https://issues.apache.org/jira/browse/SUREFIRE-1445
