JMeter 5与JUnit 5一起工作吗

Question

我在尝试使用jmeter-maven插件版本3运行JUnit 5测试套件时遇到了问题。测试套件的设置和拆卸阶段根本不会被调用。但是，会调用用@Test注释的方法。

我的设置是：

1. 第一个项目(包含JUnit测试用例(

伪测试套件(BasiTest.java(：

import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.TestInstance;
import org.junit.jupiter.api.TestInstance.Lifecycle;
@TestInstance(Lifecycle.PER_CLASS)
public class BasicTest {
public BasicTest() {
}
@Test
public void passingTest() {
System.out.println("I'm a simple test that passes!");
}
@BeforeAll
public void setUp() {
System.out.println("setUp");
}
@AfterAll
public void tearDown() {
System.out.println("tearDown");
}
}

pom.xml文件包含：

<dependencies>
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter</artifactId>
<version>5.6.2</version>
<scope>test</scope>
</dependency>
</dependencies>

2. 第二个项目(应该通过jmeter-maven插件运行第一个项目生成的jar(

pom.xml文件：

<build>
<plugins>
<plugin>
<groupId>com.lazerycode.jmeter</groupId>
<artifactId>jmeter-maven-plugin</artifactId>
<version>3.0.0</version>

</configuration>
</plugin>

JMeter测试场景(JMX文件(是：

我必须提到的是，包含JUnit测试用例(第一个项目(的jar文件是由JUnit插件加载的，用@test注释的方法正在运行(我可以在控制台中看到输出(，但设置和拆卸阶段被完全忽略了。

你知道为什么吗？

非常感谢！

Answer 1

1. JMeter自动调用setUp和tearDown函数
2. 您需要从单独的JUnit请求采样器显式调用用@BeforeClass和@AfterClass注释的函数，@BeforeAll和@AfterAll也是如此
3. 我不认为JUnit 5是官方支持的，请考虑降级到JUnit 4，否则您将独自处理您的问题

Answer 2

我认为它不起作用。。截至今天。。。当我给出JUnit 5套件类时，它给出了这个错误
