Create new report for each execution and add test steps with screenshots

[seeramzan]

Summary

I am controlling TestNG through listener where i am invocking testng methods with invocation count and providing different data sets from excel.

I have implemented extent reports listener its showing the results are per my needs. but i am not able to do the following

1) Test case description on report 2) create new report on each exectuion 3) execution steps with screenshots.

Sample

// Sample code goes here
package CommonLib.Listeners;

import TestScenarios.TestScenarios;

    }

    private void buildTestNodes(IResultMap tests, Status status) {

        if (tests.size() > 0) {
            for (ITestResult result : tests.getAllResults()) {
                int count = result.getMethod().getTotalInvocationCount();

                if (count > 1) {

                    test = extent.createTest(result.getMethod().getMethodName() + "_Iteration_" + TestScenarios.itr++);

                } else {

                    test = extent.createTest(result.getMethod().getMethodName());
                }

                    test.assignCategory(group);

                if (result.getThrowable() != null) {
                    test.log(status, result.getThrowable());
                } else {

                    test.log(status, "Test " + status.toString().toLowerCase() + "ed");

                }

                test.getModel().setStartTime(getTime(result.getStartMillis()));
                test.getModel().setEndTime(getTime(result.getEndMillis()));
            }
        }

Hi seeramzan, When you create an instance of extent report in your init() method. You if add a timestamp it might resolve your issue.

ExtentHtmlReporter htmlReporter = new ExtentHtmlReporter(dir + ReportPath + "/" + ProjectName + 
getTime(result.getStartMillis()) + FILE_NAME);

This will create a new report every time when you call init() method.
I hope this might help.
