Create separate report directory on each run using Selenium-Cucumber Maven

I am using extent reporting to generate report files in selenium-cucumber . On each run, a report is generated by overwriting the previously generated report. How can we create separate report folders by appending timestamps on each run.

The POM file that i am using is given :

It would be really helpful if you guys give an answer. Thanks in advance

Following code will generate a String object of current timestamp (you can change the format to whatever you like :

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

Now, wherever you are generating the extent report, you can pass this string inside your report name. Something like this:

extent = new ExtentReports (userDir +"\\test-output\\" + timeStamp + ".html", true);

Bonus point:

You can also add the feature name to your report for better accessibility. You can do that in your @Before hook like this:

@Before()
    public void beforeScenario(Scenario scenario)
    {
        String fileName = scenario.getName() + "-" + timeStamp;
        extent = new ExtentReports (userDir + \\test-output\\" + fileName+ ".html", true);
    }
