如何从命令行启动JUnit 5(平台)(没有Maven/Gradle)？

Question

我想从命令行运行一个包含JUnit 5测试的类.不幸的是,我有一些外部依赖项阻止我使用Maven,Gradle或其他构建系统.

在JUnit 4中,我可以完成这个

java .:"lib/*" org.junit.runner.JUnitCore TestClass

JUnit 5有相同的功能吗？我只想知道测试是否成功与IntelliJ中的运行时间相似.

TestClass.java

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import java.util.ArrayList;
import java.util.Collections;

import static org.junit.jupiter.api.Assertions.*;

public class TestClass {

    private static ArrayList<Student> students;
    private static ArrayList<Student> inAgeOrderStudents;
    private static ArrayList<Student> inNameOrderStudents;

    @BeforeAll
    static void setUp(){
        initializeStudents();
        initSortedAgeStudents();
        initSortedNameStudents();
    }

    @BeforeEach
    void reloadStudents() {
        Collections.shuffle(students);
    }

   static void initializeStudents(){
        students = new ArrayList<Student>();

        students.add(new Student(18, "Tim"));
        students.add(new Student(18, "Tim"));
        students.add(new Student(16, "Jean"));
        students.add(new Student(14, "Lin"));
        students.add(new Student(19, "Sam"));
    }

    static void initSortedAgeStudents(){
        inAgeOrderStudents = new ArrayList<Student>();
        inAgeOrderStudents.add(new Student(14, "Lin"));
        inAgeOrderStudents.add(new Student(16, "Jean"));
        inAgeOrderStudents.add(new Student(18, "Tim"));
        inAgeOrderStudents.add(new Student(18, "Tim"));
        inAgeOrderStudents.add(new Student(19, "Sam"));
    }

    static void initSortedNameStudents(){
        inNameOrderStudents = new ArrayList<Student>();
        inNameOrderStudents.add(new Student(16, "Jean"));
        inNameOrderStudents.add(new Student(14, "Lin"));
        inNameOrderStudents.add(new Student(19, "Sam"));
        inNameOrderStudents.add(new Student(18, "Tim"));
        inNameOrderStudents.add(new Student(18, "Tim"));
    }



    @Test
    void testMergeSort() {
        assertNotEquals(students, inAgeOrderStudents);
        StudentSortSearch.mergesort(students,StudentSortSearch.SortSearchCriteria.AGE);
        assertEquals(14,students.get(0).getAge());
        assertEquals(19,students.get(4).getAge());
        assertEquals(students, inAgeOrderStudents);

        assertEquals(true,students.equals(inAgeOrderStudents));
    }

    @Test
    void testQuickSort() {
        StudentSortSearch.quickSort(students,StudentSortSearch.SortSearchCriteria.NAME);
        assertEquals("Jean",students.get(0).getName());
        assertEquals("Tim",students.get(4).getName());

        assertEquals(students, inNameOrderStudents);
    }

    @Test
    void testBinarySearch() {
        StudentSortSearch searcher = new StudentSortSearch();
        ArrayList<Student> searchResults = searcher.binarySearch(students, 18);
        assertEquals(2, searchResults.size());
        assertEquals(18,searchResults.get(1).getAge());
        assertEquals(18,searchResults.get(0).getAge());

        searchResults = searcher.binarySearch(students, "Lin");
        assertEquals(1, searchResults.size());
        assertEquals(14,searchResults.get(0).getAge());
    }
}

当然,使用ConsoleLauncher.

这ConsoleLauncher是一个命令行Java应用程序,允许您从控制台启动JUnit平台.例如,它可用于运行JUnit Vintage和JUnit Jupiter测试并将测试执行结果打印到控制台.

*junit-platform-console-standalone-<version>.jar*包含所有依赖项的可执行文件发布在junit-platform-console-standalone目录下的中央Maven存储库中.您可以运行独立的ConsoleLauncher,如下所示.

java -jar junit-platform-console-standalone-<version>.jar <Options>

有关选项的详细信息,请参阅https://junit.org/junit5/docs/current/user-guide/#running-tests-console-launcher.

根据您的示例量身定制并使用JUnit Platform版本1.3.1,命令可能如下所示:

$ mkdir out
$ javac -d out Student.java StudentSortSearch.java
$ javac -d out -cp out:junit-platform-console-standalone-1.3.1.jar TestClass.java
$ java -jar junit-platform-console-standalone-1.3.1.jar --class-path out --scan-class-path

?? JUnit Jupiter ?
?  ?? TestClass ?
?     ?? test() ?
?? JUnit Vintage ?
