Ali*_*ias 32 java api automated-tests jmeter
我想使用Apache JMeter提供的API从Java程序创建和运行测试脚本.我已经了解了ThreadGroup和Samplers的基础知识.我可以使用JMeter API在我的Java类中创建它们.
ThreadGroup threadGroup = new ThreadGroup();
LoopController lc = new LoopController();
lc.setLoops(5);
lc.setContinueForever(true);
threadGroup.setSamplerController(lc);
threadGroup.setNumThreads(5);
threadGroup.setRampUp(1);
HTTPSampler sampler = new HTTPSampler();
sampler.setDomain("localhost");
sampler.setPort(8080);
sampler.setPath("/jpetstore/shop/viewCategory.shtml");
sampler.setMethod("GET");
Arguments arg = new Arguments();
arg.addArgument("categoryId", "FISH");
sampler.setArguments(arg);
但是,我不知道如何创建一个组合线程组和采样器的测试脚本,然后从同一个程序执行它.有任何想法吗？

如果我理解正确,您希望以编程方式从Java程序中运行整个测试计划.就个人而言,我发现创建测试计划.JMX文件并在JMeter非GUI模式下运行更容易:)
这是一个简单的Java示例,它基于原始问题中使用的控制器和采样器.
import org.apache.jmeter.control.LoopController;
import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.protocol.http.sampler.HTTPSampler;
import org.apache.jmeter.testelement.TestElement;
import org.apache.jmeter.testelement.TestPlan;
import org.apache.jmeter.threads.SetupThreadGroup;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;
public class JMeterTestFromCode {
public static void main(String[] args){
// Engine
StandardJMeterEngine jm = new StandardJMeterEngine();
// jmeter.properties
JMeterUtils.loadJMeterProperties("c:/tmp/jmeter.properties");
HashTree hashTree = new HashTree();
// HTTP Sampler
HTTPSampler httpSampler = new HTTPSampler();
httpSampler.setDomain("www.google.com");
httpSampler.setPort(80);
httpSampler.setPath("/");
httpSampler.setMethod("GET");
// Loop Controller
TestElement loopCtrl = new LoopController();
((LoopController)loopCtrl).setLoops(1);
((LoopController)loopCtrl).addTestElement(httpSampler);
((LoopController)loopCtrl).setFirst(true);
// Thread Group
SetupThreadGroup threadGroup = new SetupThreadGroup();
threadGroup.setNumThreads(1);
threadGroup.setRampUp(1);
threadGroup.setSamplerController((LoopController)loopCtrl);
// Test plan
TestPlan testPlan = new TestPlan("MY TEST PLAN");
hashTree.add("testPlan", testPlan);
hashTree.add("loopCtrl", loopCtrl);
hashTree.add("threadGroup", threadGroup);
hashTree.add("httpSampler", httpSampler);
jm.configure(hashTree);
jm.run();
}
}
依赖
这些是基于JMeter 2.9和使用的HTTPSampler所需的最小JAR.其他采样器很可能具有不同的库JAR依赖性.

我使用具有Maven依赖关系的JMeter Java Api创建了一个简单的概念证明项目：https : //github.com/piotrbo/jmeterpoc
您可以生成JMeter项目jmx文件并从命令行执行它，也可以直接从Java代码执行它。
这有点棘手，因为jmx文件要求每个TestElement都存在'guiclass'属性。要执行jmx，只需添加即可guiclass（即使值不正确）。要在JMeter GUI中打开，需要为每个输入正确的值guiclass。
基于条件的流量控制器是更多烦人的问题。与GUI相比，JMeter API所提供的功能不多。您仍然需要像往常一样传递condition例如。字符串应包含javascript。因此，您有一个带有javascript错误的基于Java的Java项目，例如语法错误，您将不知道它，直到执行性能测试为止：-(IfControllerString
保留代码和对IDE的支持的更好的替代方法可能是JMeter GUI，是要学习一点Scala并使用http://gatling.io/
截至 2020 年 8 月，您可以尝试使用此库：
使用 Maven，添加到 pom.xml：
<dependency>
<groupId>us.abstracta.jmeter</groupId>
<projectId>jmeter-java-dsl</projectId>
<version>0.1</version>
</dependency>
示例代码：
import static org.assertj.core.api.Assertions.assertThat;
import static us.abstracta.jmeter.javadsl.JmeterDsl.*;
import java.time.Duration;
import org.eclipse.jetty.http.MimeTypes.Type;
import org.junit.jupiter.api.Test;
import us.abstracta.jmeter.javadsl.TestPlanStats;
public class PerformanceTest {
@Test
public void testPerformance() throws IOException {
TestPlanStats stats = testPlan(
threadGroup(2, 10,
httpSampler("http://my.service")
.post("{\"name\": \"test\"}", Type.APPLICATION_JSON)
),
//this is just to log details of each request stats
jtlWriter("test.jtl")
).run();
assertThat(stats.overall().elapsedTimePercentile99()).isLessThan(Duration.ofSeconds(5));
}
}
