When you enable parallel then there will be some time between the beforeInvocation and afterInvocation in the logs as you have noticed and that difference in time varies from test to test hence the staggered output.

If what you want is the start and end messages next to each other then you are basically throwing out the time factor and as such can simply add your beforeInvocation message to the afterInvocation method as follows:

public class TestExecutionListener implements IInvokedMethodListener {

    @Override
    public void beforeInvocation(IInvokedMethod iInvokedMethod, ITestResult iTestResult) {
    }

    @Override
    public void afterInvocation(IInvokedMethod iInvokedMethod, ITestResult iTestResult) {
        System.out.println("Testing : " + iInvokedMethod.getTestMethod().getMethodName());
        System.out.println("Successfully Tested : " + iInvokedMethod.getTestMethod().getMethodName());
    }
}

IMO this is the only way to do it as per your spec. However, if there is other information that must be gathered during the tests then perhaps you could buffer some logs in the TestExecutionListener for example:

public class TestExecutionListener implements IInvokedMethodListener {
    private Map<Integer, Deque<String>> logsMap = new HashMap<Integer, Deque<String>>();

    public void log(IInvokedMethod iInvokedMethod, String log) {
        if(!logsMap.containsKey(iInvokedMethod.getId())) {
            logsMap.put(iInvokedMethod.getId(), new ArrayDeque<String>());
        }

        logsMap.get(iInvokedMethod.getId()).add(log);
    }

    @Override
    public void beforeInvocation(IInvokedMethod iInvokedMethod, ITestResult iTestResult) {
        log(iInvokedMethod, "Testing : " + iInvokedMethod.getTestMethod().getMethodName());
    }

    @Override
    public void afterInvocation(IInvokedMethod iInvokedMethod, ITestResult iTestResult) {
        log(iInvokedMethod, "Successfully Tested : " + iInvokedMethod.getTestMethod().getMethodName());

        Deque<String> logs = logsMap.get(iInvokedMethod.getId());
        while(!logs.isEmpty()) {
            System.out.println(logs.poll());
        }
    }
}

How Do You Calculate Your Test Automation ROI With Selenium?

Cross browser testing has been a type of testing which requires a tremendous amount of effort and time. The process of testing your web-app over different browsers, operating systems, devices, screen resolutions to evaluate the rendering of your web content for a variety of your audience is an activity. Especially, if approached manually. Automated cross browser testing with Selenium can help you save the time of routine test activities, helping you cut short on regression testing. However, people seldom like changes. If manual testing is popular in your organization, the management will obviously raise questions when you ask them to implement test automation.

Top Programming Languages Helpful For Testers

There are many debates going on whether testers should know programming languages or not. Everyone has his own way of backing the statement. But when I went on a deep research into it, I figured out that no matter what, along with soft skills, testers must know some programming languages as well. Especially those that are popular in running automation tests.

Nightwatch.js Tutorial For Test Automation &#8211; Complete Guide With Examples

Being an open-source framework allowed Selenium to be compatible with multiple test automation frameworks for different programming languages and if we talk about Automation testing with Selenium and JavaScript, there is a particular framework that never fails to take the spotlight and that is the Nightwatch.js. This is why I decided to come up with Nightwatch.js tutorial for beginners.

TestNG tutorial

TestNG is a Java-based open-source framework for test automation that includes various test types, such as unit testing, functional testing, E2E testing, etc. TestNG is in many ways similar to JUnit and NUnit. But in contrast to its competitors, its extensive features make it a lot more reliable framework. One of the major reasons for its popularity is its ability to structure tests and improve the scripts' readability and maintainability. Another reason can be the important characteristics like the convenience of using multiple annotations, reliance, and priority that make this framework popular among developers and testers for test design. You can refer to the TestNG tutorial to learn why you should choose the TestNG framework.
