我正在尝试在IntelliJ IDEA 2017.1.5中的同一项目中使用JUnit4和JUnit5测试。到目前为止,所有测试都基于JUnit4。我向我的pom.xml添加了
jupiter
,platform
和vintage
依赖项(包括junit-platform-surefire-provider
和junit-vintage-engine
用于surefire插件)。现在,我的JUnit4示例测试和JUnit5测试都没有执行。
相反,我得到以下错误:
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.
我尽可能地遵循了JUnit 5 用户指南中的建议,但我可能漏掉了什么。 我该如何使这两个测试都正常运行? (当然还要包括我所有已有的测试)
JUnit 4 测试类
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!");
}
}
