JUnit5中缺少org.junit.jupiter.params [英] Missing org.junit.jupiter.params from JUnit5

问题描述

我正在尝试将参数化测试添加到我的Java程序中.我找到了包含JUnit 5的示例.

I am trying to add parameterized tests into my Java program. I found the examples for JUnit 5, which I do have included.

https://blog.codefx.org/libraries/junit-5 -parameterized-tests/

问题是我无法添加@ParameterizedTest，因为缺少名称空间.知道原因或方式.

The issue is I cannot add @ParameterizedTest because the namespace is missing. Idk why or how.

文档页明确指出它在org.junit.jupiter.params中，但我没有.

The documentation page clearly states it is in org.junit.jupiter.params, but I do not have that.

让您对我的代码有所了解:

To give you an idea of my code:

import org.junit.jupiter.api.Test;

import java.util.Arrays;
import java.util.Collection;

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

class SubsetPrinterTest
{
    // https://blog.codefx.org/libraries/junit-5-parameterized-tests/

    static Collection<Object[]> makeSetData()
    {
        return Arrays.asList(new Object[][]
        {
                {1, new char[]{'1'}},
                {2, new char[]{'1', '2'}},
                {3, new char[]{'1', '2', '3'}},
                {4, new char[]{'1', '2', '3', '4'}},
                {5, new char[]{'1', '2', '3', '4', '5'}}
        });
    }

    // This should be a parameterized test using the makeSetData.
    @Test
    void makeSet()
    {
        // Arrange
        SubsetPrinter subsetPrinter = new SubsetPrinter();

        // Act
        char[] set = SubsetPrinter.MakeSet(5);

        // Assert
        assertArrayEquals(set, new char[]{'1', '2', '3', '4', '5'});
        assertEquals(set.length, 5);
    }
}

推荐答案

您的项目类路径必须包含junit-jupiter-params-xxx.jar版本，例如junit-jupiter-params-5.0.0.jar. org/maven2/org/junit/jupiter/junit-jupiter-params/5.0.0/"rel =" noreferrer> http://central.maven.org/maven2/org/junit/jupiter/junit-jupiter-params /5.0.0/

You project class-path has to include a version of junit-jupiter-params-xxx.jar, like junit-jupiter-params-5.0.0.jar from http://central.maven.org/maven2/org/junit/jupiter/junit-jupiter-params/5.0.0/

您链接到的codefx.org中的博客文章说(已编辑为当前的5.0.0版本):

The blog post from codefx.org you link to says (edited to the current 5.0.0 release):

开始进行参数化测试非常简单，但是在开始乐趣之前，您必须向项目添加以下依赖项:

Getting started with parameterized tests is pretty easy but before the fun can begin you have to add the following dependency to your project:

Group ID: org.junit.jupiter
Artifact ID: junit-jupiter-params
Version: 5.0.0

可以手动下载并添加它，或者如果您使用的是带有依赖项管理的构建工具(Gradle，Maven等)，则相应地配置构建脚本(build.gradle，pom.xml等).

Either download and add it manually, or if you're using a build tool with dependency management (Gradle, Maven, ...) configure the build script (build.gradle, pom.xml, ...) accordingly.

从版本 5.4.0-M1 开始，JUnit Jupiter提供了一个聚合器工件，它将所有可用的Jupiter定义工件捆绑在一起，以便于使用.参见 https://sormuras.github.io/blog/2018年12月26日-junit-jupiter-aggregator.html 了解详情.

Starting with version 5.4.0-M1 JUnit Jupiter provides an aggregator artifact that bundles all available Jupiter-defining artifacts for easy consumption. See https://sormuras.github.io/blog/2018-12-26-junit-jupiter-aggregator.html for details.
