Cannot run Intellij Idea's parameterized test from jmeter

I need to find a way to launch parameterized test from Intellij Idea in JMeter. Here (How to launch Intellij Idea's Java tests from JMeter?) I got good help with launching the tests, but I still cannot run the test. It seems, the test's not visible for jmeter. I added junit 5 and all its dependencies jars and all dependencies I have in my project to JMETER_HOME/lib, also I add a jar containing test classes to JMETER_HOME/lib.

Here's the code I use in JSR223 Sampler:

import org.junit.platform.launcher.Launcher
import org.junit.platform.launcher.core.LauncherDiscoveryRequestBuilder
import org.junit.platform.launcher.core.LauncherFactory
import org.junit.platform.launcher.listeners.SummaryGeneratingListener
import org.junit.platform.launcher.listeners.TestExecutionSummary

import static org.junit.platform.engine.discovery.DiscoverySelectors.selectClass;
import static org.junit.platform.engine.discovery.DiscoverySelectors.selectMethod;

import static org.junit.platform.launcher.core.LauncherDiscoveryRequestBuilder.*;

def listener = new SummaryGeneratingListener()

def request = LauncherDiscoveryRequestBuilder.request()
        .selectors(
            selectClass(com.example.MyTest.class),
            selectMethod(com.example.MyTest.class, "myTest", String.class)).build()

def launcher = LauncherFactory.create()
launcher.discover(request)
launcher.registerTestExecutionListeners(listener)
launcher.execute(request)

def summary = listener.getSummary()

log.info('Total tests executed: ' + summary.getTestsFoundCount())
log.info('Total tests succeeded: ' + summary.getTestsSucceededCount())
log.info('Total tests failed: ' + summary.getTestsFailedCount())

Logs I get:

Solution

Given you're "getting good help" you're supposed to react accordingly
Given you "still cannot run the test" you're supposed to provide the information which can help the community to identify the reason of the problem

Looking at my crystal ball I can see that you either have not added junit-jupiter-params library to your JMeter Classpath or haven't restarted JMeter after that or both.

Given you have a function like this in your com.example.MyTest.java file which looks like:

@ParameterizedTest
@ValueSource(strings = {"parameter1", "parameter2"})
public void testWithParameter(String parameter) {
    //whatever test code you want here
}

You can call it from JMeter and print the parameters to the jmeter.log file as follows:

import org.junit.platform.engine.TestExecutionResult
import org.junit.platform.launcher.TestIdentifier
import org.junit.platform.launcher.core.LauncherDiscoveryRequestBuilder
import org.junit.platform.launcher.core.LauncherFactory
import org.junit.platform.launcher.listeners.SummaryGeneratingListener

import static org.junit.platform.engine.discovery.DiscoverySelectors.selectMethod

def listener = new SummaryGeneratingListener() {
    @Override
    public void executionFinished(TestIdentifier testIdentifier, TestExecutionResult testExecutionResult) {
        def testName = testIdentifier.getDisplayName()
        def result = testExecutionResult.getStatus().toString()

        log.info('Test Case: ' + testName)
        log.info('Result: ' + result)
        log.info('------------------------------------------------------------')
    }
}

def request = LauncherDiscoveryRequestBuilder.request()
        .selectors(selectMethod(com.example.MyTest.class, 'testWithParameter', String.class))
        .build()
def launcher = LauncherFactory.create()
launcher.discover(request)
launcher.registerTestExecutionListeners(listener)
launcher.execute(request)
