3.4 Extent Reports

Extent Reports is a multi-format reporting library for Java Developers which creates an interactive HTML report, an email report, and also provides real-time log information. The ExtentAPI also integrates with the ExtentX server to provide in-depth views of your tests.

Extent addresses the reporting issues in TestNG. Below is the code which can be used to run tests

package code;

import java.io.File;
import java.util.HashMap;
import java.util.Locale;
import java.util.Map;

import com.relevantcodes.extentreports.DisplayOrder;
import com.relevantcodes.extentreports.ExtentReports;
import com.relevantcodes.extentreports.NetworkMode;

import CONSTANTS;

public class ExtentManager {
    public static ExtentReports extent;
    protected static final String filePath=System.getProperty("user.dir")+File.separator
    +"ExtentReports"+File.separator+"AutomationTestReport.html";
    private static boolean replaceExisting=true;
    protected static final DisplayOrder displayOrder= DisplayOrder.NEWEST_FIRST;

    public static ExtentReports getInstance(String EnvironmentToRunOn) {
        if (extent == null) {
            extent = new ExtentReports(filePath, replaceExisting,displayOrder, NetworkMode.OFFLINE); 
            extent.loadConfig(new File(ExtentXMLConfigPath));
            Map<String, String> sysInfo = new HashMap<String, String>();
            sysInfo.put("Selenium Version", "2.53.1");
            sysInfo.put("Environment", EnvironmentToRunOn);
            extent.addSystemInfo(sysInfo);            
        }
        return extent;
    }
}

class ExtentReports {

    public ExtentReports extent;
    public ExtentTest test;
    public String getCurrentlyLoggedInUser=System.getProperty("user.name");

    @Test       
   public void InitializeExtentReport(){
        //Instantiating the ExtentReports
        extent=ExtentManager.getInstance(Environment);
        extent.assignProject("Test Extent");
        // start x requires MongoDB hence commented to generate reports on the other machines
        Logger mongoLogger = Logger.getLogger( "org.mongodb.driver" );
        mongoLogger.setLevel(Level.SEVERE);
        extent.x("localhost");*/
        test=extent.startTest("Test1", ""Application started." );
        test.assignAuthor(getCurrentlyLoggedInUser);
        test.assignCategory("RegressionTestCases");
        }
    }

We need to keep in mind that the extent reports must be under @Test annotation of TestNG otherwise it will not generate the reports.

After running the tests we will be able to view report in the specified folder as "AutomationTestReport.html"
