would activeReporters = Collections.singletonList(REPORTER); can reporter be unique to each class rather than one report for all..

[nagkumar]

public final class JUnitPerfInterceptorSuite extends JUnitPerfInterceptor
{
    private static final HtmlReportGenerator REPORTER = newHtmlReporter("suite_reporter.html");
    private static final DescriptiveStatisticsCalculator statisticsCalculator = new DescriptiveStatisticsCalculator();

    @Override
    public void postProcessTestInstance(Object testInstance, ExtensionContext context) throws Exception
    {
	activeReporters = Collections.singletonList(REPORTER);
	activeStatisticsCalculator = statisticsCalculator;

	defaultRequirementsAnnotation = new JUnitPerfTestRequireme

Also, as active report is always the same as it is now..

why is it needed to call this once per each test

activeReporters = Collections.singletonList(REPORTER);

Would you also consider not to have separate report that is parallel to unit test report, is it possible to include perf metrics within existing junit report

I definitely like this

[nagkumar]

would consider not to change existing JUnit report with another file names etc..

can you consider to hook perf info within the existing junit report
