JUnit 5测试用例未执行
我在NetBeans 8.2中的一个新的干净Maven项目中创建了这个测试：
import static org.junit.jupiter.api.Assertions.fail; import org.junit.jupiter.api.Test; public class JUnit501Test { @Test void firstTest() { fail("epicly"); } } 如果我运行测试，则会显示日志
------------------------------------------------------- TESTS ------------------------------------------------------- Running JUnit501Test Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0 sec Results : Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
我的pom.xml包含这个依赖项：
org.junit.jupiter junit-jupiter-api 5.0.1 test
什么可能导致JUnit 5忽略测试方法？
更新：我添加了surefire插件，这是完整的pom.xml：
4.0.0 com.timeshuttle Junit5Test 1.0-SNAPSHOT jar org.junit.jupiter junit-jupiter-api 5.0.1 test org.junit.jupiter junit-jupiter-engine 5.0.1 test UTF-8 1.8 1.8 org.apache.maven.plugins maven-surefire-plugin 2.20.1 org.junit.platform junit-platform-surefire-provider 1.0.1 org.junit.jupiter junit-jupiter-engine 5.0.1
输出更改为：

surefire-reports文件夹包含两个“.dump”文件。 第一个内容：
# Created on 2017-10-16T16:17:32.959 java.lang.NoSuchMethodError: org.apache.maven.surefire.report.RunListener.testSetStarting(Lorg/apache/maven/surefire/report/ReportEntry;)V at org.junit.platform.surefire.provider.JUnitPlatformProvider.invokeSingleClass(JUnitPlatformProvider.java:137) at org.junit.platform.surefire.provider.JUnitPlatformProvider.invokeAllTests(JUnitPlatformProvider.java:126) at org.junit.platform.surefire.provider.JUnitPlatformProvider.invoke(JUnitPlatformProvider.java:105) at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:373) at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:334) at org.apache.maven.surefire.booter.ForkedBooter.execute(ForkedBooter.java:119) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:407)
确保您的maven-surefire-plugin配置正确：
org.apache.maven.plugins maven-surefire-plugin 2.19.1 org.junit.platform junit-platform-surefire-provider 1.0.1 org.junit.jupiter junit-jupiter-engine 5.0.1 ${argLine}
并且您不需要引擎作为依赖项，因此您可以从
org.junit.jupiter junit-jupiter-engine 5.0.1 test
注意 ：关于使用maven运行测试的Junit5的官方文档指定使用surefire 2.19.1，因为插件的2.20发行版本中存在内存泄漏。
