如何从我的testng报告中获得控制台输出？

import org.testng.IReporter;
import org.testng.ISuite;
import org.testng.xml.XmlSuite;

import java.util.List;
import java.util.Map;

public class ConsoleReporter implements IReporter {
    @Override
    public void generateReport(List<XmlSuite> xmlSuites, List<ISuite> suites, String outputDirectory) {
        // 遍历所有的测试套件
        for (ISuite suite : suites) {
            Map<String, ISuiteResult> results = suite.getResults();
            // 遍历每个测试套件的结果
            for (ISuiteResult result : results.values()) {
                ITestContext context = result.getTestContext();
                // 获取控制台输出的日志
                List<String> logOutput = context.getFailedTests().getAllResults().stream()
                        .flatMap(testResult -> testResult.getTestContext().getFailedTests().getAllResults().stream())
                        .map(ITestResult::getThrowable).map(Throwable::getMessage).collect(Collectors.toList());
                // 打印控制台输出
                for (String log : logOutput) {
                    System.out.println(log);
                }
            }
        }
    }
}

<suite name="Sample Suite">
    <listeners>
        <listener class-name="com.example.ConsoleReporter"/>
    </listeners>
    ...
</suite>
