How to customize Selenium TestNG default report or create new HTML report? - selenium

Question

I tried ReportNG, but it is not updating the report now & I found that ReportNG is no more used from this answer.
I want to create a test report/customize TestNG report to gave to development team. I used Hybrid Framework for creating the project and followed this tutorial.

Answer 1

Yes, you can customize the TestNG reports using Listeners and Reporters. Here is the link of documentation. It is not clear from a question what type of customization you want to do.
But I want to suggest better alternatives for reporting here. There are two most used libraries which generally used with Selenium.
Allure Test Report
Extent Report.
I have not used Allure test reports but it seems to be good and widely used in the community. I have had used Extent Reports in two projects and really happy with it. Anshoo Arora has done the remarkable job. Documentation is very good with lot of example & code snippet. I would highly recommend it.

Answer 2

To customize selenium TestNG report, you can use testng listeners.
ITestListener: Log Result/Screenshot on test pass/fail/skip.
IReporter: To generate html report from xml suite results and log.
But as an alternative you can use qaf-reporting.
It provides Detailed Live Reporting (Don`t need to wait for complete execution).

Answer 3

I know this is old thread, but these reports can be edited and custom reports can be made like below. I have also explained here how TestHTMLReporter can be edited . And if you would like to know , how index.html report is customized have a look here , where I have explained it in detail
With your customReport You'd have to implement IReporter , extend TestListenerAdapter and override generateReport method if you want to implement a custom TestHTMLReporter . For other reporters you may have to do things a bit differently but the concept will remain the same. You'd achieve custom 'TestHTMLReporter' like below .
Create a CustomReport.java file in your project and copy-paste the whole content of TestHTMLReporter.java , change the name of file in getOutputFile method and it would look like below
public class CustomReport extends TestListenerAdapter implements IReporter {
#Override
public void generateReport(List<XmlSuite> xmlSuites, List<ISuite> suites,
String outputDirectory) {
}
...
//paste the content of TestHTMLReporter.java here
...
...
Make sure all your imports are in place from TestHTMLReporter.java
Now, in this file change as per your requirement . For ex: if you'd like to add the end time of each of the test then at the correct place in generateTable method add the below snippet
// Test class
String testClass = tr.getTestClass().getName();
long testMillis = tr.getEndMillis();
String testMillisString = Long.toString(testMillis);
if (testClass != null) {
pw.append("<br>").append("Test class Name: ").append(testClass);
// this line to add end time in ms
pw.append("<br>").append("End Time(ms): ").append(testMillisString);
// Test name
String testName = tr.getTestName();
if (testName != null) {
pw.append(" (").append(testName).append(")");
}
Then you'll get like below
Now, You'll get two reports one with default and the other with your file name.
The only thing now remains is switching off the default reporting listeners, so you get only one report. For that you can follow this or you may search for solutions. Hope this helps
