Utilizing ScreenshotCapture in IReporter for TestNG with Selenium

When working with TestNG and Selenium for automated testing, capturing screenshots can be a valuable tool for debugging and verifying the test results. In this article, we will explore how to utilize the ScreenShotCapture class within IReporter for TestNG, focusing on scenarios where an object repository is based on the Page Object Model (POM) or Page Object Factory (POF). By following the steps outlined below, you will be able to successfully capture and store screenshots within the testing framework.

Overview of ScreenshotCapture in IReporter

In TestNG, the IReporter interface allows you to customize the reporting process. When combined with the ScreenShotCapture class, it enables the automatic capture of screenshots during the execution of your tests. This is particularly useful when your object repository uses either the POM or POF model.

Steps to Utilize ScreenshotCapture

Step 1: Creating a Class for Screenshot Capture

The first step involves creating a dedicated class specifically for taking screenshots. This class should be designed to capture the screenshots and save them in a specified location. The following code snippet outlines an example of how to set up such a class:

import ;
import ;
import ;
import ;
import ;
public class ScreenshotHandler implements IReporter{
    @Override
    public void generateReport(ListString methods, ITestResult result, boolean status) {
        WebDriver driver  (WebDriver) ().getTestClass().getRealClass().getDeclaredField("driver").get(());
        File scrFile  ((TakesScreenshot) driver).getScreenshotAs();
        try {
            File destFile  new File(path/to/destination   /   );
            (scrFile, destFile);
        } catch (IOException e) {
            ();
        }
    }
}

In this class, the generateReport method is overridden to capture the screenshot when a test is executed. The screenshot is then saved with the name "" in the specified path.

Step 2: Configuring IReporter in TestNG

To use this custom IReporter class, you need to configure it in your TestNG XML configuration file. Here is an example configuration:

test nameMyTest
  parameter namebrowser valuechrome/
  listeners
    listener class-name
  /listeners
  classes
    class namePackageName.TestClass1 /
  /classes
/test

Make sure to replace with the fully qualified class name of your ScreenshotHandler class.

Step 3: Running Your TestNG Suite

Once the IReporter is configured, you can run your TestNG suite as usual. The generateReport method of your ScreenshotHandler class will be called automatically for each test method, saving the screenshots in the specified location.

Conclusion

Utilizing the ScreenShotCapture functionality within IReporter for TestNG and Selenium can greatly enhance your testing process by providing a visual reference of each test step. By following the steps outlined in this article, you can effectively manage and capture screenshots in a structured manner, making debugging and verification easier.
