eclipse - 如何将 JUnit 5 与现有 Eclipse 项目集成？

Question

现有的 Eclipse 项目使用 Maven，但不了解 JUnit。我应该/可以将 JUnit 集成到现有项目中，还是应该创建一个专用于 JUnit 的新项目，或者是否有更好的选择？

Answer 1

您可以通过在 pom.xml 中包含以下依赖项来将 JUnit5 添加到该项目:

<properties>
    <junit.jupiter.version>5.0.1</junit.jupiter.version>
    <junit.platform.version>1.0.1</junit.platform.version> 
</properties>

<!--
    JUnit5 dependencies:
     * junit-jupiter-api: for writing JUnit5 tests
     * junit-jupiter-engine: for running JUnit5 tests
     * junit-platform-xxx: the foundation for JUnit5
     * (Optionally) you might want to include junit-vintage-engine for running JUnit4 tests       
-->
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>${junit.jupiter.version}</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>${junit.jupiter.version}</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-launcher</artifactId>
    <version>${junit.platform.version}</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-runner</artifactId>
    <version>${junit.platform.version}</version>
    <scope>test</scope>
</dependency>

要使 Maven Surefire 能够运行 JUnit5 测试，只需在 pom.xml 中包含以下插件定义:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${maven.surefire.plugin.version}</version>
    <configuration>
        <excludes>
            <exclude>**/MongoPopulatorTool.java</exclude>
        </excludes>
    </configuration>
    <dependencies>
        <!-- integrates JUnit5 with surefire -->
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>${junit.platform.version}</version>
        </dependency>
        <!-- ensures that a JUnit5-aware test engine is available on the classpath when running Surefire -->
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>${junit.jupiter.version}</version>
        </dependency>
    </dependencies>
</plugin> 

最后，要使 Eclipse 的测试运行程序能够运行 JUnit5 测试，您必须运行 Eclipse Oxygen.1a (4.7.1a) 版本(或更高版本)，请查看 Eclipse docs .
