Trying to spin up 2 test nodes for Integration Testing

Elastic Stack Elasticsearch
1

Hi,

I have written a ES plugin (using version ES 7.5.2) which I have been able to test successfully using a single node integration test environment. However, I have faced issues when running the same code on multiple nodes in the actual ES environment. I would like to recreate the issue locally for debugging my code, but I can't find a way to create a 2 node integration test environment.
Here is my build.gradle file

    import org.elasticsearch.gradle.testclusters.TestClustersRegistry
    import org.elasticsearch.gradle.testclusters.TestClustersPlugin

    buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "org.elasticsearch.gradle:build-tools:7.5.2"
    }
    }

    apply plugin: 'java'
    apply plugin: 'idea'
    apply plugin: 'elasticsearch.esplugin'

    version = rootProject.file('VERSION.txt').text.trim()

    esplugin {
    description 'Elasticsearch scoring plugin'
    classname 'com.test.TestPlugin'
    name project.name
    version project.version
    licenseFile rootProject.file('LICENSE.txt')
    noticeFile rootProject.file('NOTICE.txt')
    }

    configure(rootProject) {
    TestClustersRegistry registry = rootProject.extensions.create("testClustersRegistry", TestClustersRegistry)
    TestClustersPlugin.configureClaimClustersHook(project.gradle, registry)
    TestClustersPlugin.configureStartClustersHook(project.gradle, registry)
    TestClustersPlugin.configureStopClustersHook(project.gradle, registry)
    }

    testClusters.integTest {
    testDistribution = 'DEFAULT'
    }

The 'elasticsearch.esplugin' plugin spins a node with the name 'integTest-0' under 'test clusters' in the build folder. Is there a way to create another node in the 'integTest' cluster.

Thank you very much in advance.
