Junit STS-未找到测试跑步者'Junit 5的测试 [英] Junit STS - No test found with test runner 'Junit 5
问题描述
我已经从 https://howtodoinjava复制了Spring Batch程序. com/spring-batch/java-config-multiple-steps/'.
我已经从创建了以下JUnit测试用例https://docs.spring.io/spring-batch/docs/current/reference/html/testing.html :
package com.example.demo;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.test.JobLauncherTestUtils;
import org.springframework.batch.test.context.SpringBatchTest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.junit.Assert;
import org.junit.jupiter.api.*;
import org.junit.runner.RunWith;
@SpringBatchTest
@RunWith(SpringRunner.class)
@ContextConfiguration(classes=DemoSpringBatch1Application.class)
class DemoSpringBatch1ApplicationTests {
@Autowired
private JobLauncherTestUtils jobLauncherTestUtils;
@Test
public void testJob() throws Exception {
JobExecution jobExecution = jobLauncherTestUtils.launchJob();
Assert.assertEquals("COMPLETED", jobExecution.getExitStatus().getExitCode());
}
}
我的Maven pom文件是:
My Maven pom file is:

I tried changing dependencies mentioned by Gerold and hbattac as Eclipse No tests found using JUnit 5 caused by NoClassDefFoundError for LauncherFactory. I tried modifying the junit libraries.
我仍然收到以下错误:
java.lang.NoSuchMethodError: org.junit.platform.launcher.Launcher.execute(Lorg/junit/platform/launcher/TestPlan;[Lorg/junit/platform/launcher/TestExecutionListener;)V

Java构建路径如下所示:

推荐答案
代替@RunWith(SpringRunner.class)，它是JUnit 4，使用@ExtendWith(SpringExtension.class)，这是木星的方法.
Instead of @RunWith(SpringRunner.class), which is JUnit 4, use @ExtendWith(SpringExtension.class) which is Jupiter´s way to do it.
出于一致性原因，您还应该使用org.junit.jupiter.api.Assertions中的断言方法.然后，您可以完全摆脱对JUnit 4的依赖.我通常在pom.xml中使用以下子句来排除JUnit4
You should also use assertion methods from ˋorg.junit.jupiter.api.Assertionsˋ for consistency reasons. Then you can get rid of your dependency on JUnit 4 altogether. I usually have the following clause in pom.xml to exclude JUnit4
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
<exclusion>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
</exclusion>
</exclusions>
</dependency>
您还需要最新版本的surefire插件才能与JUnit 5配合使用:
You also need a recent version of the surefire plugin to work with JUnit 5:
<build>
<pluginManagement>
<plugins>
<!-- JUnit 5 requires Surefire version 2.22.1 or higher -->
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.2</version>
</plugin>
</plugins>
</pluginManagement>
</build>
