JUnit4和JUnit5测试未在IntelliJ中运行 [英] JUnit4 and JUnit5 tests not running in IntelliJ

问题描述

我试图在IntelliJ IDEA 2017.1.5的同一项目中使用JUnit4和JUnit5测试.到目前为止，所有测试都基于JUnit4.我在我的pom.xml中添加了jupiter，platform和vintage依赖项(包括surefire插件的junit-platform-surefire-provider和junit-vintage-engine). 现在，我的针对JUnit4的示例测试和针对JUnit 5的示例测试都没有执行.

I am trying to use JUnit4 and JUnit5 tests in the same project in IntelliJ IDEA 2017.1.5. Until now, all tests were based on JUnit4. I added the jupiter, platform and vintage dependencies to my pom.xml (including the junit-platform-surefire-provider and junit-vintage-engine for the surefire plugin). Now, neither my example test for JUnit4 nor the one for JUnit 5 are executed.

相反，出现以下错误:

Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;
    at org.junit.platform.launcher.core.ServiceLoaderTestEngineRegistry.loadTestEngines(ServiceLoaderTestEngineRegistry.java:30)

    at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70)

Process finished with exit code 1
Empty test suite.

我试图遵循 JUnit 5用户指南中的建议，尽可能接近，但我可能错过了一些东西. 如何使两个测试正常运行?(当然还有我所有的现有测试)

I tried to follow the advice from the JUnit 5 User Guide as closely as possible but I probably missed something. How can I get both tests to run properly? (and all my existing tests, of course)

package com.glaed.util;

import org.junit.Test;

public class JUnit4Test {

  @Test
  public void helloJUnit4Test() {
    System.out.println("Hello JUnit4!");
  }

}

JUnit 5测试类

package com.glaed.util;

import org.junit.jupiter.api.Test;

class JUnit5Test {

  @Test
  void helloJU5test() {
    System.out.println("Hello JUnit5!");
  }
}

推荐答案

使用以下版本的junit-jupiter-api:

<dependency>
  <groupId>org.junit.jupiter</groupId>
  <artifactId>junit-jupiter-api</artifactId> 
  <version>5.0.0-M4</version>
  <scope>test</scope>
</dependency>

并在版本5.0.0-M4上用于所有junit-jupiter依赖项.

And also use on version 5.0.0-M4 for all junit-jupiter dependencies.
