无法从jmeter运行Intellij Idea的参数化测试

Question

我需要找到一种方法在 JMeter 中从 Intellij Idea 启动参数化测试。在这里（如何从 JMeter 启动 Intellij Idea 的 Java 测试？）我在启动测试方面得到了很好的帮助，但我仍然无法运行测试。看来，测试对于 jmeter 来说是不可见的。我将 junit 5 及其所有依赖项 jar 以及我的项目中的所有依赖项添加到 JMETER_HOME/lib 中，还将一个包含测试类的 jar 添加到 JMETER_HOME/lib 中。

这是我在 JSR223 Sampler 中使用的代码：

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())

我得到的日志：

Answer 1

1. 鉴于您“得到了良好的帮助”，您应该做出相应反应
2. 鉴于您“仍然无法运行测试”，您应该提供信息，这可以帮助社区确定问题的原因

看着我的水晶球，我可以看到您要么没有将 junit-jupiter-params 库添加到您的 JMeter Classpath，要么在那之后没有重新启动 JMeter，或者两者都没有。

假设您的 com.example.MyTest.java 文件中有一个类似的函数，如下所示：

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

您可以从 JMeter 调用它并将参数打印到 jmeter.log 文件，如下所示：

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)
