为什么 Maven 找不到任何测试？

Question

我有以下测试class

package com.mk.calculator.add;

import org.junit.jupiter.api.Assertions;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;

import java.util.ArrayList;
import java.util.List;

public class AddFunctionTest {
    @ParameterizedTest
    @CsvSource({ "-1, 1, 0", "0,0,0", "-100,200,100","100,400,500" })
    public void shouldAddTwoNumbers(final int first,final int second, final long result){
        AddFunction af = new AddFunction();
        List<Number> input = new ArrayList<>();
        input.add(first);
        input.add(second);
        Number output = af.calculate(input);
        Assertions.assertEquals(result,output);
    }
    @Test
    public void shouldAddMultipleNumbers(){
        AddFunction af = new AddFunction();
        List<Number> input = new ArrayList<>();
        input.add(1);
        input.add(2);
        input.add(3);
        input.add(4);
        input.add(5);
        input.add(6);
        input.add(7);
        input.add(8);
        input.add(9);
        input.add(10);
        Number output = af.calculate(input);
        Assertions.assertEquals(55l,output);
    }
    @Test
    public void shouldReturnSameNumber(){
        AddFunction af = new AddFunction();
        List<Number> input = new ArrayList<>();
        input.add(1);
        Number output = af.calculate(input);
        Assertions.assertEquals(1l,output);
    }
    @Test
    public void shouldReturnZero(){
        AddFunction af = new AddFunction();
        List<Number> input = new ArrayList<>();
        Number output = af.calculate(input);
        Assertions.assertEquals(0l,output);
    }
    @Test
    public void shouldworkOnNegatives(){
        AddFunction af = new AddFunction();
        List<Number> input = new ArrayList<>();
        input.add(-1);
        input.add(-9);
        Number output = af.calculate(input);
        Assertions.assertEquals(-10l,output);
    }
}

并遵循 Maven 配置：

            <scope>test</scope>
        </dependency>
    </dependencies>


</project>

maven 找到测试 class，但未在其中找到任何测试。但是，我可以从 IDE.

执行测试

请帮助我确定我在这里遗漏了什么。

您需要配置 Maven Surefire 插件才能使用 junit-platform-surefire-provider，例如：

<build>
    <plugins>
        ...
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <configuration>
                <includes>
                    <include>**/Test*.java</include>
                    <include>**/*Test.java</include>
                    <include>**/*Tests.java</include>
                    <include>**/*TestCase.java</include>
                </includes>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>org.junit.platform</groupId>
                    <artifactId>junit-platform-surefire-provider</artifactId>
                    <version>${junit.platform.version}</version>
                </dependency>
            </dependencies>
        </plugin>
    </plugins>
</build>
