測試套件從 JUnit4 遷移到 JUnit5

Question

我已經將我項目中的所有 JUnit 測試從版本 4 遷移到版本 5。該項目由幾個 Maven 模塊和項目組成，如下面的架構

• 父母pom
  • 后端項目
  • 核心項目
    • 一些模塊
    • 測試套件模塊
      • 測試套件.java
  • ... 一些其他項目

在 TestSuite.java 中，我在 Junit4 下有以下代碼

import org.junit.extensions.cpsuite.ClasspathSuite;
import org.junit.extensions.cpsuite.ClasspathSuite.ClassnameFilters;
import org.junit.runner.RunWith;

@RunWith(ClasspathSuite.class)
@ClassnameFilters({"common.package.of.all.projects.*"})
public class TestSuite {
   
}

現在我嘗試在 JUnit5 下創建等效配置

import org.junit.platform.suite.api.SelectPackages;
import org.junit.platform.suite.api.Suite;

@Suite
@SelectPackages("common.package.of.all.projects.*")
public class TestSuite {
    
}

這是測試套件模塊pom.xml的摘錄

// this lib help to execute the test suite under eclipse
<dependency>
  <groupId>io.takari.junit</groupId>
  <artifactId>takari-cpsuite</artifactId>
  <scope>test</scope>
</dependency>
// these are the test dependencies I added
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-suite-api</artifactId>
    <version>1.8.2</version>
    <scope>test</scope>
 </dependency>
 <dependency>
      <groupId>org.junit.platform</groupId>
      <artifactId>junit-platform-suite-engine</artifactId>
      <version>1.8.2</version>
      <scope>test</scope>
 </dependency>
 // all module are in the dependencies like the following
 <dependency>
      <groupId>${project.groupId}</groupId>
      <artifactId>module.name</artifactId>
      <version>${project.version}</version>
      <type>test-jar</type>
      <scope>test</scope>
  </dependency>
  ...

我使用 IntelliJ IDE 和 JDK 17.0.5，
但是當我嘗試運行測試套件時，沒有啟動任何測試。 盡管我在dependenciesToScan中添加了模塊，但似乎沒有找到
這是我收到的警告

正如Spring Boot 2.2 關於此警告的另一篇錯誤“具有 ID 'junit-vintage' 的 TestEngine 未能發現測試”中所建議的，我在 spring-boot-starter-test 的父 pom 中添加了對 junit.vintage 的排除

<dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-test</artifactId>
          <version>${spring.boot.version}</version>
          <scope>test</scope>
          <exclusions>
            <exclusion>
              <groupId>org.junit.vintage</groupId>
              <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
          </exclusions>
        </dependency>

所以我可能在我的配置中遺漏了一些東西，或者這不是實現我想要的東西的正確方法。
有任何想法嗎？ 謝謝 ！

您必須將junit-platform-suite-engine和junit-jupiter-engine作為依賴項。

它們都需要使用 JUnit Jupiter 運行套件。

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.junit</groupId>
        <artifactId>junit-bom</artifactId>
        <version>5.9.1</version>
        <scope>import</scope>
        <type>pom</type>
      </dependency>
  </dependencyManagement>

  <dependencies>
    <dependency>
      <groupId>org.junit.platform</groupId>
      <artifactId>junit-platform-suite-engine</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-engine</artifactId>
      <scope>test</scope>
    </dependency>
  </dependencies>
