如何在空手道加特林中每秒加载更多请求

我正在尝试重用空手道脚本并使用加特林执行负载测试。定义的场景是每秒加载 50 个用户，持续 10 秒。 （对 500 个用户进行负载测试）但是，gatting 报告中每秒的请求数不超过 20 个请求。如果我做错了什么，请告诉我。 执行空手道脚本的ExampleTest.java代码

//package examples;

import com.intuit.karate.Results;
import com.intuit.karate.Runner;
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.Test;
import java.io.File;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
import net.masterthought.cucumber.Configuration;
import net.masterthought.cucumber.ReportBuilder;
import org.apache.commons.io.FileUtils;

class ExamplesTest {
    
    @Test
    void testParallel() {
        //System.setProperty("karate.env", "demo"); // ensure reset if other tests (e.g. mock) had set env in CI
        Results results = Runner.path("classpath:examples").tags("~@ignore").parallel(10);
        generateReport(results.getReportDir());
        assertEquals(0, results.getFailCount(), results.getErrorMessages());        
    }
    
    public static void generateReport(String karateOutputPath) {        
        Collection<File> jsonFiles = FileUtils.listFiles(new File(karateOutputPath), new String[] {"json"}, true);
        List<String> jsonPaths = new ArrayList<String>(jsonFiles.size());
        jsonFiles.forEach(file -> jsonPaths.add(file.getAbsolutePath()));
        Configuration config = new Configuration(new File("target"), "demo");
        ReportBuilder reportBuilder = new ReportBuilder(jsonPaths, config);
        reportBuilder.generateReports();        
    }
    
}

用于定义负载测试场景的 Scala 代码。

package perf

import com.intuit.karate.gatling.PreDef._
import io.gatling.core.Predef._
import scala.concurrent.duration._

class KarateSimulate extends Simulation {
    

    val protocol = karateProtocol(
    "/v2/" -> Nil,
    "/v2/" -> pauseFor("get" -> 0, "post" -> 25)
    )
    val userfeeder = csv("data/Token.csv").circular

    val getScores = scenario("Get Scores for Students").feed(userfeeder).exec(karateFeature("classpath:examples/scores/student.feature"))

    setUp(
        getScores.inject(constantUsersPerSec(50) during (10 seconds)).protocols(protocol)
    )   
}

我们更新了文档（在develop分支），并提供有关如何在需要时增加线程池大小的提示：https://github.com/intuit/karate/tree/develop/karate-gadling#increasing-thread-pool-size https://github.com/intuit/karate/tree/develop/karate-gatling#increasing-thread-pool-size

添加一个名为gatling-akka.conf到类路径的根（通常src/test/resources）。这是一个例子：

akka {
  actor {
    default-dispatcher {
      type = Dispatcher
      executor = "thread-pool-executor"
      thread-pool-executor {
        fixed-pool-size = 100
      }
      throughput = 1
    }
  }
}

由于我们最近做了一些修复，如果上述方法不适用于 0.9.6.RC4，请尝试从源代码构建，这很简单，以下是说明：https://github.com/intuit/karate/wiki/Developer-Guide https://github.com/intuit/karate/wiki/Developer-Guide
