JUnit 5测试用例未执行 [英] JUnit 5 test case not executed
本文介绍了JUnit 5测试用例未执行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在NetBeans 8.2的一个新的干净Maven项目中创建了此测试:
I created this test in a new clean Maven project in NetBeans 8.2:
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，日志将显示
If I run the tests, the log shows
-------------------------------------------------------
T E S T S
-------------------------------------------------------
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包含此依赖项:
My pom.xml contains this dependency:
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-api</artifactId>
<version>5.0.1</version>
<scope>test</scope>
</dependency>
什么会导致JUnit 5忽略测试方法?
What could cause JUnit 5 to ignore the test method?
更新:我添加了surefire插件，这是完整的pom.xml:
Update: I added the surefire plugin, here is the full pom.xml:

推荐答案
确保您的maven-surefire-plugin正确配置为:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version> <!-- Specific due to memory leak in 2.20 -->
<dependencies>
<!--Custom provider and engine for Junit 5 to surefire-->
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-surefire-provider</artifactId>
<version>1.0.1</version>
</dependency>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.0.1</version>
</dependency>
</dependencies>
<configuration>
<argLine>${argLine}</argLine>
</configuration>
</plugin>
，并且不需要引擎作为依赖项，因此可以从<dependencies>标记中删除它:-
and you don't need the engine as dependencies, so you can remove this from your <dependencies> tag :-
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-engine</artifactId>
<version>5.0.1</version>
<scope>test</scope>
</dependency>
注意 :Junit5的官方文档，关于使用maven进行测试指定使用surefire 2.19.1.
Note: The official documentation of the Junit5 about running tests with maven specifies using surefire 2.19.1 due to a memory leak in the 2.20 release version of the plugin.
